A Michigan-identified public storefront with stock-aware variation pricing, reproducible quantity and cart-spend discounts, and a large current-and-historical multi-laboratory certificate registry.
ezPeps exposes a stock-aware public variation catalog and a structured multi-laboratory certificate registry. PeptideBenchmark keeps temporary sales, standing same-product tiers, first-order savings, payment incentives, rewards, shipping, and optional package protection in separate pricing lanes.
Testing transparency: Public multi-laboratory COA archive with exact provider verification. Exact provider-controlled routes support reports from Freedom Diagnostics, ILS Laboratories, Horizon Analytical, TrustPointe, and Kovera Labs. Deterministic Janoshik task/key routes remain source-linked when the provider challenges ordinary unattended verification, while a current row without a public source URL is recorded as an evidence gap rather than inferred. Panel coverage is shown per certificate rather than inherited across the archive.

Open profileA Sunrise, Florida storefront with a broad public catalog, stock-aware regular pricing, independently modeled sale and bundle lanes, and a deep public certificate library retaining current and historical documents.
Go Alpha Labs exposes 175 publicly listed catalog records, 70 currently in-stock comparable retail-vial offers, formal shipping and returns terms, and 253 distinct public certificate origins. PeptideBenchmark preserves regular prices as the base, models temporary per-product sales separately, and does not assume they stack with the bundle.
Testing transparency: Provider verification for 162 of 253 certificate origins. Every document linked from the public /coas/ library is byte-validated, fingerprinted, read for laboratory and panel context, and related to its published product context. Exact provider checks confirm 132 Freedom Diagnostics and 30 BioRegen reports. The remaining 91 origins stay preserved and source-linked without being mislabeled as failed, invalid, or independently verified.

Open profileAn Arizona-positioned public WooCommerce storefront with exact variation pricing, visible subscription and shipping terms, and a catalog-wide certificate library whose reports resolve independently at Freedom Diagnostics.
Unyx exposes 31 public product parents, 47 currently in-stock comparable vial offers, and one current Freedom Diagnostics certificate for each of 27 retail peptide product families. PeptideBenchmark uses one-time list prices by default, keeps subscription and first-order savings opt-in, and separates laboratory-reported identity, purity, and net content from vendor-stated safety badges.
Testing transparency: Catalog-wide Freedom Diagnostics reports with live provider verification. All 27 public library rows resolve under the UNYX Peptides client at Freedom Diagnostics; 26 originate at the laboratory and the vendor-hosted Kisspeptin copy matches the provider report. The linked reports support identity, HPLC/LC-MS purity, and net content. They do not support the storefront’s repeated sterility or endotoxin badges, and one product-family certificate is not treated as independent testing of every listed strength.

Open profileA Cary, North Carolina storefront with a public stock-aware catalog, an anonymous-cart discount that can be reproduced without an account, and a large multi-batch certificate library spanning current and retained historical records.
Oros Research exposes 58 catalog products and a large public multi-batch certificate library backed by Supabase-hosted PDFs. As of August 4, 2026, 202 certificate origins / 203 documents currently resolve with zero HTTP 404 destinations on a fresh probe. PeptideBenchmark models only in-stock, safely comparable vial rows and keeps vendor-stated fields, document-extracted values, and provider verification separate.
Testing transparency: Current source-linked PDFs plus provider-linked batch reports. Refreshed August 4, 2026: certificate files moved from Shopify CDN images to stable coas-public PDF ids (short-lived signed storage redirects). Live discovery now lists 202 certificate origins (105 Ethos Analytics, 92 Freedom Diagnostics, 5 Vanguard Labs) with 0 excluded 404 destinations. The retained evidence layer includes 89 exact provider-linked historical batch reports; the replacement PDFs remain source-linked until targeted archive hashing and document-specific provider recovery complete. PB does not transfer a provider-verification badge from an older document by lot alone, and prior Shopify CDN objects remain preserved as historical evidence.

Open profileA Denver-shipped public WooCommerce catalog with standing single-vial prices and a public certificate archive whose Kovera report codes resolve at the laboratory’s public verify lookup.
Vector Amino Labs exposes a public research-peptide catalog and a certificate-of-analysis page that pairs each current lot image with a laboratory report code. PeptideBenchmark ranks the regular per-vial list price and treats sitewide sale pricing as a separate observed lane.
Testing transparency: Public COA archive with Kovera Labs provider verification. The public archive publishes certificate images with Kovera Labs report codes that resolve at the laboratory’s public verify lookup, plus one ILS Laboratories card. Most current single-vial products have a matched certificate; kits, bac water, and non-peptide injectables are outside the peptide board. A matched certificate documents the tested sample and does not endorse every vial or unlisted safety panel.

Open profileA Houston-stated U.S. research storefront with openly listed cart prices and a public /coa archive of Freedom Diagnostics, ILS Laboratories, and Kovera Labs certificates that resolve at the issuing laboratories, with Freedom and ILS reports naming the Void Research client.
Void Research sells research-only singles, blends, and nasal sprays with cart prices on the public shop, including house codes GLP-2 TZ for tirzepatide and GLP-3 RT for retatrutide, plus GLOW, KLOW, and BPC/TB blends. The public /coa page publishes Freedom Diagnostics, ILS Laboratories, and Kovera Labs certificates per batch, keeping superseded reports alongside their replacements; PeptideBenchmark confirms printed Freedom Search Codes and the ILS portal verify route (token or printed Access Code) when the client field names Void Research, and Kovera KVR report codes at the laboratory’s public verify endpoint. Nasal sprays and reconstitution/support SKUs stay outside the retail single-vial board.
Testing transparency: Public COA archive with Freedom Diagnostics, ILS, and Kovera provider verification. The public /coa archive hosts Freedom Diagnostics, ILS Laboratories, and Kovera Labs Certificate-of-Analysis documents whose Search Codes, portal verify routes, or KVR report codes resolve at the issuing laboratory; Freedom and ILS reports name Void Research in the client field. Published certificates typically support identity, HPLC purity, and net content for the named sample; ILS and Kovera reports add endotoxin and, on covered batches, sterility, heavy-metals, and fentanyl-screen fields. A matched certificate documents the tested sample and does not endorse every vial or unlisted lot.

Open profileAn independent research-peptide marketplace with openly listed multi-source kit prices and public /verify batch pages whose Freedom Diagnostics, Janoshik, and Bioviridian certificates resolve at the issuing laboratories.
Peptuvia is a multi-source research marketplace rather than a single manufacturer storefront: product pages list independent sources with per-potency kit prices, and fulfillment is vendor-stated to ship from regional warehouses or direct from the named source. House codes RT and TR map to retatrutide and tirzepatide on the pricing board. Public /verify/{code} pages publish Freedom Diagnostics Search Codes (Pept…), Janoshik Analytical reports normalized to exact tests/{task}_{key}, and Bioviridian Web Verification Codes (COA######) that PeptideBenchmark confirms at the laboratory. Some vendor-hosted /coa mirrors redact Freedom Search Codes or link dead Accumark PDFs, so those lots stay outside provider-verified evidence. Oral, vitamin, and non-peptide support SKUs stay outside the injectable kit board.
Testing transparency: Public /verify batch pages with Freedom, Janoshik, and Bioviridian provider verification. Batch pages under /verify publish Freedom Diagnostics Certificate-of-Analysis documents whose Search Codes resolve at the laboratory under Peptuvia-prefixed client names (for example Peptuvia - Sentinel), Janoshik Analytical reports live-verified at exact tests/{task}_{key} paths, and Bioviridian certificates whose COA###### codes resolve at bioviridians.com. Published certificates typically support identity and HPLC purity for the named marketplace batch and source; they do not endorse every warehouse listing or later lot on the same product page.

Open profileA U.S.-operated research storefront with openly listed single-vial and multipack prices and per-product Freedom Diagnostics certificates that resolve at the laboratory’s public lookup under the Endura client name.
Endura Peptides sells research-only singles and blends with prices on the product pages, including house codes GLP-2T for tirzepatide and GLP-3R for retatrutide, plus KLOW, BPC/TB, and Ipamorelin/CJC blends. Each catalog peptide links downloadable Freedom Diagnostics certificates; PeptideBenchmark confirms printed Search Codes against Freedom’s public index when the client field names Endura. Quantity multipacks and bacteriostatic water stay outside the retail single-vial board.
Testing transparency: Public product-page Freedom Diagnostics COAs with provider verification. Product pages host Freedom Diagnostics Certificate-of-Analysis PDFs whose Search Codes resolve at the laboratory’s public verification surface under the Endura client name.

Open profileA U.S.-based research storefront (also styled EnhancedChem; legal entity Advanced Chems LLC) with openly listed single-vial prices, a public /coa/ Freedom Diagnostics archive under client Enhanced Chem, and additional product-page Janoshik certificate image scans.
Enhanced Chems sells research-only injectable vials with standing list prices on the product pages, including house codes GLP2 for tirzepatide and GLP-3 RT for retatrutide, plus GLOW, KLOW, and BPC/TB blends. The public /coa/ page publishes Freedom Diagnostics PDFs whose Search Codes resolve at the laboratory under client Enhanced Chem. Many product galleries also show Janoshik Analytical certificate scans; those published scans blank Task Number, Unique Key, and Client, so they remain vendor-hosted documents rather than independently re-checkable portal reports.

The public /coa/ archive hosts Freedom Diagnostics Certificate-of-Analysis PDFs whose Search Codes resolve at the laboratory’s public verification surface under the Enhanced Chem client name. Reports typically support identity, HPLC purity, and net content for the named sample. Additional product-page Janoshik image scans document purity when readable but blank Task Number, Unique Key, and Client on the published asset, so they are not treated as independently re-checkable at the laboratory portal. A matched certificate documents the tested sample and does not endorse every vial or unlisted safety panel.

Amino Science exposes a stock-aware public catalog of single-vial research peptides and a public COA library that links each current certificate straight to its Freedom Diagnostics report. PeptideBenchmark uses the regular per-vial list price as the base and keeps the sitewide percentage sale and select buy-one-get-one offers as separate optional lanes.
Testing transparency: Public COA library with live Freedom Diagnostics provider verification. Each library certificate links to a report hosted at Freedom Diagnostics that resolves under the Amino Science client name at the laboratory’s public accession lookup, supporting identity, HPLC/LC-MS purity, and net content. Most products publish a certificate per listed strength; a strength-specific report is not treated as testing every other strength, and the storefront’s marketing purity language is not inherited onto sterility or endotoxin panels the reports do not run.

Rescue Research USA exposes its current catalog and a searchable public COA table without requiring an account. PeptideBenchmark preserves each certificate, batch, product relationship, fingerprint, laboratory attribution, and exact provider route where the report independently resolves.
Testing transparency: Public provider-linked batch reports from Freedom and ILS. The July 28 review found 33 distinct certificates: 27 canonical Freedom Diagnostics reports and six ILS Laboratories PDFs. Three ILS reports expose exact public verification tokens; three older ILS PDFs identify the laboratory but expose only a generic lab URL and therefore do not receive a provider-verification badge.

Open profileA Denver, Colorado storefront that publishes its full priced catalog openly and attaches laboratory certificates directly to the products they describe, with most of those reports carrying an independently checkable credential.
Mile High Peptide lists 49 products and 57 comparable research-vial rows across 36 distinct peptides, all readable without an account. Certificates are published as page images inside each product gallery rather than in a separate library, so PeptideBenchmark reads every published image and keeps laboratory-confirmed values separate from what the certificate picture alone shows.
Testing transparency: Product-attached certificates with provider verification at ILS and Kovera. The August 7, 2026 review found 14 distinct certificates across 12 product pages. Ten resolve independently at the issuing laboratory — five ILS Laboratories reports whose portal tokens return the certificate under the Mile High Peptide client name, and five Kovera Labs reports whose printed codes resolve to lab-hosted documents. The remaining four are BTLabs certificates: the laboratory is named and the printed identity, purity, potency and appearance results are recorded, but BTLabs operates no public report lookup, so those reports are not given a verification badge. Panel coverage is identity, purity and net content throughout, with endotoxin reported on two ILS reports; sterility is not reported on any certificate in this set.

Open profileA Nebraska-identified storefront that gates HTML product browsing behind an account while serving its full priced catalog and an unusually deep certificate library to anyone, with current, historical, and discontinued batch routes all visible.
Peptira requires an account to browse products in a web page, but not to read them: its public catalog endpoint returns the full priced range to an anonymous request, and its COA library is deeper than the gated storefront suggests. PeptideBenchmark normalizes that catalog to $/mg from the vendor’s own dosage attribute, verifies documents against the issuing laboratory where an exact report route resolves, and preserves separate current, historical, and discontinued batch context.
Testing transparency: Exact Freedom Diagnostics provider verification across a deep public batch archive. The public library spans 303 distinct certificate routes. Exact provider checks confirm 217 Freedom Diagnostics reports at the issuing laboratory under the Peptira client name. Thirty-three exact Janoshik task/key routes remain source-linked pending a provider recheck, and 53 further origins — 32 older Peptira-hosted report pages and 21 documents still awaiting extraction — carry no laboratory attribution yet. Certificates are not given fabricated exact-product matches.

Open profileA public storefront identifying a Wyoming postal address and separately stating in-house fulfillment from Virginia, with exact stock-aware pricing, unusually deep same-product volume tiers, and a certificate library that retains failed and depleted batch history.
Giga Compounds exposes its current catalog, inventory, cart discount composition, fulfillment schedule, and a searchable public COA library without an account. The vendor says orders ship by FedEx 2-Day from its temperature-controlled Virginia facility, with weekday fulfillment until 2 PM EST. PeptideBenchmark preserves each source PDF, exact product relationship, batch status, panels, fingerprint, and independently checkable laboratory route where one resolves.
Testing transparency: Public multi-lab COA library with Janoshik and Kovera provider verification. As of Aug 12, 2026 the public library has 38 downloadable certificate PDFs spanning Janoshik Analytical, Kovera Labs, and Chromate (up from 34 on July 28). It still includes active, depleted, pending, and seven rejected reports rather than silently hiding failed batches. Eleven of those reports check out on the lab’s own verify page (10 Janoshik + 1 Kovera). One library row still points only at Janoshik’s generic verify page, which cannot identify a specific report.

Open profilePeptide Tech ended its public peptide storefront on August 26, 2026. PeptideBenchmark retains the last public catalog prices and the previously reviewed certificate library as dated historical evidence, not current retail offers.
On August 26, 2026, Peptide Tech announced it was ending its peptide storefront and shifting to lyophilization, filling, and later API synthesis, with a remaining white-label fulfillment program. PeptideBenchmark keeps the last public prices observed August 25 and the previously reviewed public COA library. Those prices are excluded from current Pricing and Stack Builder. The former shopper referral path no longer reaches a Peptide Tech retail checkout.
Testing transparency: Retained public multi-lab COA library with report-level provider verification. The last public COA library contained 162 distinct lot documents from Freedom Diagnostics, Vanguard Laboratory, Janoshik Analytical, Chromate, and SafeCert. PB validates the document bytes and exact product relationship for every retained record. In the July 27 review, 104 distinct Freedom and six Chromate reports resolved at the issuing laboratory; the eight older Janoshik documents no longer resolved at Janoshik’s current verifier and remain named-lab evidence without a provider badge. That library is no longer on the live site; the archive is retained as historical evidence.

Most retained reports resolve byte-for-byte at Freedom Diagnostics; eight additional vendor-hosted certificates remain visible as source-linked documents where the laboratory cannot yet be independently identified.
Testing transparency: Product-level COAs with report-specific Freedom provider verification. The tested current Alpha Pro vial line exposes certificate widgets on covered product pages. PeptideBenchmark validates 35 distinct certificate origins against Freedom Diagnostics’ provider host under the Alpha Pro Peptides client name and preserves eight additional vendor-hosted documents without assigning them an unidentified laboratory or provider badge. The retained documents report identity and HPLC purity broadly, with net content on the provider-resolved set; they do not currently report sterility, endotoxin, or heavy-metals panels.

Open profileA Tempe, Arizona storefront that leads with same-day shipping and an unusually data-rich public testing layer, worth tracking as a transparency-forward US vendor.
Publishes a structured, per-batch COA archive covering the whole catalog — quantitative purity, average net content (fill accuracy), vials tested, and an endotoxin / heavy-metals / sterility safety panel per batch, all openly inspectable. That is a stronger public-evidence pattern than generic "COA available" language, though the testing is vendor-published rather than run through an outside verification portal.
Testing transparency: Public COA archive with per-batch purity and safety panel. Instant Peptides exposes a public lab-tests archive with per-batch, per-concentration certificates: quantitative HPLC purity, average net content, vials-tested counts, and endotoxin / heavy-metals / sterility results. The documents are vendor-published — no named third-party lab or externally verifiable report code — so it sits in the public-docs lane rather than provider-verified.
Profile:instant-peptides
Open profileIncluded because it is the clearest catalog-wide public-verification case in the current site and now acts as the strongest public-testing anchor in the vendor graph.
Still the cleanest repeated public third-party verification trail we have: product pages route directly into Janoshik-hosted result pages and Janoshik verification pages across a large portion of the catalog.
Testing transparency: Public Janoshik report + verification trail. EZ repeatedly exposes public “View Latest Lab Test Result” behavior that routes readers into Janoshik-hosted report pages and Janoshik verification pages. That is stronger than a vendor-hosted PDF archive because the verification step lives on the outside provider domain rather than only on the vendor domain.

Peptide Partners publishes an Independent Certifications archive spanning purity, endotoxin, heavy metals, and sterility, and the bulk of it resolves to its issuing labs — Kovera Labs (live-verifiable at koveralabs.com), Chromate, TrustPointe Analytics, and BioRegen. That makes most of the archive provider-verifiable third-party evidence, not just vendor-hosted files.

Open profileIncluded because it is part of the manually selected research-vendor watchlist, even though the current dataset name is shorter.
A strong public-verification case: its product-page COA grid holds per-lot third-party reports from Horizon Analytical and Freedom Diagnostics — 108 of them independently verifiable at the testing lab, averaging 99.5% purity, with separate endotoxin files on many products.
Testing transparency: Per-lot Horizon Analytical & Freedom Diagnostics COAs with public provider verification. Blank product pages expose a visible COA grid whose purity reports are third-party: Horizon Analytical (per-lot code searchable at horizonanalytical.com/verify-coa) and Freedom Diagnostics (public accession lookup), plus per-product endotoxin files. 108 lots carry a code that resolves on the testing lab’s own public verify surface, so this is outside-provider verification, not just vendor-hosted documentation. Note the public manufacturing trail is still thinner than the document trail: the site makes strong U.S.-made / cGMP-style claims, but the specific Missouri cGMP manufacturing partner is not clearly identified in the public materials we reviewed, and a May 21, 2026 public question from Disclosed Labs asking which Missouri cGMP lab Blank uses does not appear to have a public answer attached.

Testing transparency: Per-product Freedom Diagnostics COAs with public provider verification. Elite Research USA gates its storefront behind a member sign-in, but every certificate image is served from a PUBLIC S3 bucket (eliteresearch-public.s3…/certificates/), anonymously reachable. The certificates are third-party: 65 are Freedom Diagnostics COAs carrying a public accession/search code (e.g. Elit2602020426) independently verifiable at freedomdiagnosticstesting.com, plus Vanguard Laboratory reports (named accredited lab; Elite’s Vanguard COAs are not in Vanguard’s public per-COA database). Average verified purity ≈99.7%. So the underlying evidence is public provider-verifiable, even though the browsing experience is login-first.

Open profileIncluded because it is one of the more repeatedly cited U.S. research-vendor names in current transparency-focused community lists and clearly belongs in the same comparison set as Peptide Partners, Kimera Chems, and Elite Research USA.
Nearly every product carries a public MZ Biolabs certificate set — HPLC-UV purity (averaging ~99.7%), mass-spec identity, and an endotoxin report — a genuinely deep named-lab document layer, though MZ offers no public per-COA lookup, so the certificates are inspectable rather than independently verifiable at the lab.
Testing transparency: Public sitemap-derived COA / MS / endotoxin image layer. Pure Peptides names MZ Biolabs as its third-party testing lab and publishes a per-product certificate set — HPLC-UV purity (~99.7% average), mass-spec identity, and endotoxin — as public image assets across most of the catalog. That is a strong named-lab document layer, but MZ Biolabs exposes no public per-COA verification lookup, so these read as inspectable vendor-hosted certificates from a named lab rather than provider-run verification that a reader can confirm at the lab’s own site.
Tracked under the current benchmark dataset name "Pure Peptides Bio."
Profile:pure-peptides-bio
Open profileIncluded as part of the community-known shortlist, with a normalized dataset match already in place.
Now one of the stronger curated testing-transparency candidates because its public COAs page exposes a structured COA map rather than just generic lab-testing language.
Testing transparency: Public COA map with provider verification. Peptide Plugs publicly exposes vendor-hosted COA files and Freedom Diagnostics accession-based verification links from its public COAs page, which is a meaningfully stronger pattern than vague homepage purity claims.
Tracked under the current dataset name "PeptidePlugs."
Profile:peptideplugs
Open profileIncluded because its broad catalog exposes repeatable public COA archive paths across many products.
A large, provider-verified COA archive: a public per-batch API surfaces a Freedom Diagnostics search code for nearly every product, and those codes resolve live in Freedom’s public index.
Testing transparency: Freedom Diagnostics provider verification across the archive. Simple Peptide publishes a public COA archive (a WordPress `coa-archive` REST API) that exposes a Freedom Diagnostics search code, purity, net content, and panels for each batch. In the latest audit, 139 of 183 certificate origins across 52 products independently resolved to a real Freedom Diagnostics report in the lab’s public index (a fake code correctly returns not-found), at ~99.5% average purity. The remaining ~44 are older attributable vendor documents kept without a provider badge.
Profile:simple-peptide
Open profileIncluded as a community-known research vendor we want to keep surfaced even before deeper editorial coverage lands.
No longer just a hold-and-watch name. The live site exposes a real public COA archive with outside-provider links, plus a public shop/catalog surface that makes Orbitrex a meaningful trust-review candidate rather than a placeholder.
Testing transparency: Public COA archive with provider-linked batch reports. Orbitrex publicly exposes a `/coas/` archive with batch-level certificate links. PeptideBenchmark validates the underlying Dropbox documents and live provider reports rather than treating every listed link as evidence; the current archive includes validated Kovera, Chromate, TrustPointe, ILS Laboratories, Freedom Diagnostics, and Dropbox-hosted records.
Profile:orbitrex-peptides
Open profileIncluded as an active name in the curated watchlist and already connected to a live vendor profile.
A genuine multi-lab case: its public test-results page publishes certificates from four independent labs — Janoshik, BioRegen, Chromate, and MZBiolabs — and the first three each expose a public verifier, so a dozen of Evolve’s reports can be checked directly at the lab rather than taken on the vendor’s word.
Testing transparency: Provider verification across four independent labs (Janoshik, BioRegen, Chromate, MZBiolabs). Evolve publicly exposes a `/test-results/` page and an open shop surface rather than a login-first catalog. Across its public COA set, twelve reports are independently provider-verifiable: Janoshik test reports resolve at verify.janoshik.com by task number and printed key, BioRegen certificates carry a public COA/security-key pair, and Chromate reports validate against chromate.org by job number and access code. The remaining certificates are from MZBiolabs — a named third-party lab that publishes HPLC purity and dedicated endotoxin reports but has no public per-certificate lookup, so those count as named-lab evidence rather than provider-verified. Reported HPLC purity averages ~98.4%, with endotoxin panels on ten products.
Profile:evolve-peptides
Open profileIncluded in the current focus set as a now-mapped research vendor with a public rebrand and address trail.
A standout verified case: a deep public per-batch archive links roughly two hundred Freedom Diagnostics certificates — a named outside lab — each carrying an accession / Search Code that resolves in Freedom’s public lookup, with exact HPLC purity averaging ~99.6% and endotoxin results on many batches.
Testing transparency: Third-party Freedom Diagnostics COAs with public provider verification. Oath publishes a public per-batch COA archive (a WordPress lab-results library) where every certificate is from Freedom Diagnostics, an outside lab, and its accession / Search Code is independently checkable at the provider’s public lookup. The reports carry HPLC-UV purity (~99.6% average), LC-MS identity, and endotoxin results on many batches — broad, provider-verifiable evidence across the catalog, not just vendor-hosted documents.
Profile:oath-research
Open profileIncluded because it is now one of the stronger high-ranked consensus vendors we want visible in the curated layer, and it exposes a real public lab-reports surface rather than only generic testing language.
One of the deeper public certificate trails in the catalog: nearly every product carries third-party Janoshik Analytical reports — split by test type (purity, endotoxin, TFA/net content, and in some cases sterility) — with reported purity averaging around 99% and each report independently confirmable at the lab.
Testing transparency: Third-party Janoshik Analytical COAs with public provider verification. Verified Peptides publishes per-product Janoshik Analytical “TEST REPORT” certificates, and each carries a task number plus a unique key that resolves the report two-factor at verify.janoshik.com — so the certificate can be confirmed at the lab rather than taken on the vendor’s word. Because it posts separate reports per test type, many peptides carry not just a purity number but endotoxin and sometimes sterility panels, which is broader safety coverage than most vendors publish.
Profile:verified-peptides
Open profileIncluded because it is a high-ranked consensus vendor with explicit lot-linked COA positioning and a visible public COA lookup path.
Now a real public searchable-COA case rather than just promising positioning. Paramount exposes a public COA lookup that returns lot-linked vendor-hosted COA images across a meaningful slice of the catalog.
Testing transparency: Searchable Janoshik COA lookup. Paramount exposes a searchable COA lookup by product name or lot number, and the results resolve to Janoshik Analytical reports at verify.janoshik.com — a third-party provider verification flow, not just vendor-hosted images. The pass found repeated public result rows with lot numbers and analysis dates across a broad product sitemap.
Profile:paramount-peptides
Open profileIncluded because it ranks highly on the board and now has a real trust-review surface rather than just a score-driven placeholder.
Stronger than the first gated impression: Mile High publishes per-product COA images through its product sitemap and backs a broad slice of its catalog with Kovera Labs and Chromate verification links that resolve at those labs' public portals.
Testing transparency: Public COA images with Kovera + Chromate provider verification. Mile High publishes per-product COA images openly through its product sitemap, and its product pages carry Kovera Labs and Chromate verification links that resolve at those labs' public portals — provider-verifiable evidence across a broad slice of the catalog, alongside sterility and endotoxin safety panels on many products. The storefront routes anonymous visitors into a research-access gate, but the certificates and their third-party verification are inspectable.
Profile:mile-high-compounds
Open profileIncluded because it has a more intentional public operator and Texas-based positioning than many thin storefronts, and we want that pattern represented in the curated set.
Forge looks more operator-forward than many smaller vendors: Texas-based language, batch-tested messaging, and a public /coas/ archive that pairs current cards with historical PDFs. The current review retains 49 distinct certificate documents across 22 covered products; 41 current or historical reports resolve at Freedom Diagnostics, ILS Laboratories, BioRegen, or Kovera Labs.
Testing transparency: Multi-lab provider verification across current and historical batches. PeptideBenchmark reads every current and historical PDF exposed on /coas/, not only the structured current-card credentials. Forty-one retained reports currently resolve at Freedom Diagnostics, ILS Laboratories, BioRegen, or Kovera Labs. The remaining vendor-hosted documents stay named-lab or source-linked evidence without an unearned provider badge, including a Vanguard Laboratory report and an HPLC report without a public laboratory lookup. Panel coverage is report-specific: the current product set broadly reports identity, with HPLC, net content, endotoxin, and sterility on narrower subsets; no heavy-metals result is inferred from documents that do not report it.
Profile:forge-performance-co
Open profileIncluded because it is now a known U.S.-footprint vendor with explicit COA-on-site language and a current live storefront worth comparing against stronger transparency leaders.
Puratek now reads as a real public certifications-archive case with a thinner but meaningful public batch-report surface tied to named outside-lab language.
Testing transparency: Freedom Diagnostics provider verification archive. Puratek’s public `/coa/` and `/certifications/` archive resolves its batch reports to Freedom Diagnostics (accession-searchable at FreedomDiagnosticsTesting.com), with at least one ILS Laboratories report in the set. That is provider-verifiable public evidence, not just vendor-hosted images.
Profile:puratek-peptides
Open profileIncluded because it is one of the stronger public-facing trust candidates in this expansion batch, with named outside labs and a visible public COA path.
One of the strongest public certificate trails in the catalog: a public /coa-lookup/ gallery pairs each product with batch-level third-party lab reports — Freedom Diagnostics, Chromate, and Kovera Labs — with reported purity averaging around 99.6%, and nearly every certificate can be confirmed at the issuing lab.
Testing transparency: Freedom Diagnostics + Chromate COAs with public provider verification. GenPeptide’s public /coa-lookup/ gallery lists batch-level reports across the catalog, and the large majority can be checked at the lab rather than taken on the vendor’s word: Freedom Diagnostics reports resolve by accession on the lab’s public search, Chromate reports by their two-factor job + access code confirmed live at chromate.org, and a set of Kovera Labs reports by their KVR code. Roughly nine in ten of the certificates carry a live provider-verification link — broad, provider-verifiable public evidence rather than generic third-party language.
Tracked under the current benchmark dataset name "Genpeptide."
Profile:genpeptide
Open profileIncluded because it now has a clearer U.S. footprint, visible COA navigation, and a public quality-assurance layer that is stronger than a bare storefront.
The lab-results layer turns out to be substantial: a public /lab-results/ library maps most of the catalog to per-batch third-party reports — Freedom Diagnostics and Kovera Labs — and nearly every one can be confirmed at the issuing lab, with a set of products also carrying separate endotoxin reports.
Testing transparency: Third-party Freedom Diagnostics + Kovera Labs COAs with public provider verification. Ion’s public /lab-results/ library lists per-batch reports across roughly a hundred products, and the large majority can be checked at the lab rather than taken on the vendor’s word: Kovera Labs reports resolve by their KVR code on Kovera’s public lookup, and Freedom Diagnostics reports by their accession on Freedom’s public COA search. A subset of products publish separate Freedom endotoxin reports on top of purity. That is broad, provider-verifiable public evidence rather than the performative lab page it first appeared to be.
Profile:ion-peptides
Open profileIncluded because it is a U.S.-listed research vendor already on the board and now part of the active affiliate/curated comparison set.
A dual-lab, provider-verified COA case: the public COA library links a certificate for nearly every catalog product, and those certificates independently resolve at two third-party labs — BioRegen and Janoshik Analytical.
Testing transparency: Dual-lab provider verification (BioRegen + Janoshik). NextGenPeps publishes a public COA library whose certificates come from two independent third-party labs: BioRegen (purity/identity COAs, verifiable at bioregen.com/report by COA number + security key) and Janoshik Analytical (image COAs including dedicated endotoxin panels, verifiable at verify.janoshik.com). In the latest audit, 49 of 52 unique COAs independently resolved to a real provider-hosted report — covering 33 of 40 catalog products — at an average reported purity of 99.6%. Because each certificate can be confirmed against the lab that issued it, this is genuine outside-provider verification, not a vendor-hosted document pattern.
Profile:nextgenpeps
Open profileIncluded because its catalog is openly browsable and selected product pages link to exact Freedom Diagnostics reports that can be checked on the provider-controlled report host.
Peptime pairs an openly browsable catalog with five exact product-linked Freedom Diagnostics reports. All five currently resolve on the provider-controlled report host, with reported HPLC purity, identity, and net-content results.
Testing transparency: Selected Freedom Diagnostics reports with provider verification. Five of 15 reviewed Peptime products link to exact Freedom Diagnostics reports, and all five currently resolve on the laboratory-controlled report host. The reports average about 99.7% stated purity and include HPLC, identity, and net-content results. This is genuine provider-linked evidence, but one-third catalog coverage remains materially narrower than a broad whole-catalog archive.
Profile:peptime
Open profileIncluded because Ameano now exposes a clean public WooCommerce catalog plus a public COA archive page with vendor-hosted report images, which is enough to compare honestly without pretending it is a provider-run verification system.
Ameano publishes a public COA archive of Janoshik Analytical reports — 60 of them independently verifiable at verify.janoshik.com (the report’s task number + on-report unique key), averaging ~99.4% purity — alongside open simple-product pricing.
Testing transparency: Public COA archive of Janoshik reports with two-factor provider verification. Ameano’s public COA archive page links a Janoshik Analytical report image per product. Each one deep-resolves at verify.janoshik.com via its printed task number + unique key, so the certificate opens the actual provider report in one click rather than being just a vendor-hosted image — 60 verify this way, averaging ~99.4% purity. The storefront explicitly marks some pre-sale items as pending COA, so coverage is meaningful but not the entire catalog.
Profile:ameano-peptides
Open profileIncluded because APR pairs a clean public WooCommerce catalog with a per-product COA image from a named third-party lab (Janoshik Analytical), which is materially more than generic purity language even though the reports stop short of one-click verification.
An openly browsable simple-product catalog where the product-gallery COA images are Janoshik Analytical TEST REPORTs — reading them shows ~99.5% average HPLC purity with identity and net-content quantitation, each stamped with a Janoshik task number.
Testing transparency: Product-gallery COA images from a named third-party lab. Every product-gallery COA is a Janoshik Analytical TEST REPORT (~99.5% average purity across 26 products, with a Janoshik task number). Janoshik is a reputable third-party lab, but these reports print only the task number, not the on-report unique key, so they can’t be deep-verified two-factor at verify.janoshik.com — this is strong named-lab documentation, not one-click provider verification.
Profile:american-peptide-research
Open profileIncluded because it pairs live public pricing with exact-product certificate coverage across every current catalog product. ILS Laboratories and Freedom Diagnostics records retain provider-checkable routes, while Ethos Analytics certificates remain explicitly labeled vendor-document evidence.
Amino Club has a substantive batch-level testing record spanning ILS Laboratories, Freedom Diagnostics, and Ethos Analytics, with provider-checkable reports kept distinct from vendor-published certificates that lack an independent public verification portal.
Testing transparency: Provider verification for ILS and Freedom reports plus labeled Ethos vendor documents. PB requires every current Amino Club catalog product to retain at least one exact-product certificate relationship. ILS Laboratories and Freedom Diagnostics reports expose provider-checkable routes. Ethos Analytics certificates come from Amino Club’s public registry and downloadable document links; because Ethos exposes no independent public verifier, those records remain vendor-stated rather than provider-verified. Individual records show only the identity, purity, net-content, endotoxin, sterility, and heavy-metals evidence actually reported.
Profile:amino-club
Open profileIncluded because Apex is on the current curated-expansion list and already exists in the broader benchmark dataset under a clean matched vendor slug.
Now a meaningful public-transparency case rather than just a queued vendor. Apex exposes a public /products catalog with live dosage-level pricing on product pages, plus a separate public /verify COA browser and product-page Certificate of Analysis callouts.
Testing transparency: Public product-page COA plus public verify browser. Apex publicly exposes two useful trust surfaces: product pages carry a visible Lab Verified / Certificate of Analysis callout, and the separate /verify browser exposes per-product COA routes on the vendor domain. That is materially stronger than generic testing language alone, while still remaining a vendor-hosted documentation pattern rather than a provider-controlled live verification system.
Profile:apex-peptides
Open profileIncluded because Nationwide is a disclosed affiliate relationship and exposes a public WooCommerce storefront plus 68 attributable Freedom Diagnostics certificates across 45 current products. Sixty resolve to exact laboratory-owned report objects; eight remain preserved vendor copies whose corresponding provider URLs currently return 404.
A public catalog with clearly listed products, live variable-product pricing, and 68 downloadable Freedom Diagnostics certificates across 45 products. The reviewed documents average about 99.1% HPLC-UV purity and report identity and net content; 60 have exact laboratory-controlled verification routes.
Testing transparency: Freedom Diagnostics provider verification. Nationwide currently exposes 68 attributable Freedom Diagnostics certificates across 45 of 73 catalog products. PeptideBenchmark matched 60 to exact Freedom-owned PDFs by client, search code, accession, and lot. The remaining eight are retained as source-linked vendor documents because their expected laboratory objects currently return 404; they are not labeled independently verified.
Profile:nationwide-peptides
Open profileIncluded because it is a disclosed affiliate relationship and a distinct storefront from apexpepts.com, so we should track it separately rather than collapsing the two Apex domains into one vendor identity.
A separate Apex storefront with an account-gated shop and stable product routes. Signed-in review confirms usable pricing and product-page COA sections, which makes it a real gated comparison case rather than just a placeholder identity.
Testing transparency: Product-page COAs with Freedom Diagnostics provider verification. Apex-Peptides.com product pages carry 144 certificate images with exact product relationships across 23 products. Of those, 58 provider-linked reports resolve at Freedom Diagnostics; the full reviewed set averages roughly 99.6% reported purity. The storefront's shopping and pricing experience remains account-gated, but the verified lab evidence is publicly checkable at the provider.
Profile:apex-peptides-com
Open profileIncluded because it now has real structured coverage: a public product sitemap, live product-page pricing, and a small but genuine public lab-results surface.
A mixed but still legitimate public case. Next Chems exposes a browsable public storefront with product-level pricing and inline dosage variants, while the trust side currently rests on a narrow public COA page plus repeated product-page “COA available” language rather than a broad certificate archive.
Testing transparency: Partial public lab-results archive. Next Chems currently exposes a small public lab-results / COAs page with vendor-hosted PDFs, and many product pages also make an explicit public COA-available claim. That is enough to create a real trust profile, but it is still much narrower than the broad archive or provider-run verification patterns we treat as stronger proof tiers.
Profile:next-chems
Open profileIncluded because it pairs a complete public structured pass (product sitemap, live product-page pricing, a dedicated public lab-test archive) with third-party COAs from Bioviridian Inc. that are independently verifiable at the lab’s own domain.
A broad public storefront with product-page variation pricing and a per-product lab-test archive. The reviewed archive includes Bioviridian Inc. certificates — ~99.8% average purity with unusually deep panels (HPLC, identity, endotoxin, and heavy-metals) — whose Web Verification Codes resolve at bioviridians.com.
Testing transparency: Bioviridian provider verification. LA Peptides’ lab-test pages embed Bioviridian Inc. COAs whose Web Verification Codes (COA######) resolve to lab-hosted records. The current review found 78 provider-verifiable certificate-to-product relationships among 98 reviewed relationships; those map to 77 distinct Bioviridian documents because one certificate supports two related product pages. This is independent-provider public evidence, not just vendor-hosted images.
Profile:la-peptides-net
Open profileIncluded because every product-attached certificate is a third-party Bioviridian Inc. COA that resolves at the lab’s own domain, while the public catalog exposes standing prices — a fully checkable pricing and testing pass without relying on a vendor-stated testing claim.
A WooCommerce storefront whose testing evidence is far deeper than it first appears. No product description mentions testing at all, and the vendor’s own certificate index sits behind an account, yet each product carries a Bioviridian Inc. certificate as an attached document — third-party HPLC-MS with identity, purity, endotoxin, and heavy-metals panels, each printing a Web Verification Code the lab hosts and resolves. Every certificate read names PepLogix on its face, so attribution comes from the issuing lab rather than from us.
Testing transparency: Bioviridian provider verification. Each PepLogix product attaches a Bioviridian Inc. COA. Every certificate prints a Web Verification Code (COA######) that the lab hosts at bioviridians.com/coas/<code>.pdf and resolves through its public coa-search.html lookup, and each one PeptideBenchmark read was confirmed against that host — a fabricated code 404s there, so the check distinguishes a real certificate from a published image. The certificates also name PepLogix as the vendor, so attribution is stated by the lab.
Profile:peplogix
Open profileIncluded for its retained pricing record. PeptideBenchmark previously captured 29 directly comparable rows from Strand Bio’s public price list; those accepted rows remain as a dated comparison because PeptideBenchmark has not restamped them as a new anonymous quote. The September 7 public-markup audit detected no Strand Bio testing evidence on 83 reachable research, compliance, and catalog pages after the researcher-login route migrated to the public catalog, while otherwise unlabelled raster image pixels remain outside that claim.
PeptideBenchmark retains 29 formerly public catalog records, each with one vial size and one accepted price, so the dated range still normalizes to $/mg without a deferral. Catalog HTML is now publicly reachable after the researcher-login route migrated to the public catalog; PeptideBenchmark has not restamped those August 15 rows as a new anonymous quote. On September 7, PeptideBenchmark checked 83 publicly reachable research, compliance, and catalog pages, fourteen exact certificate-route 404s, and 1 exact authentication gate reached from public links: the partner feed returned its reviewed 401 approved-researcher response after the researcher-login route migrated to the public catalog. It found no certificate, purity figure, batch identifier, laboratory name, or verification code in the audited public markup. Otherwise unlabelled image pixels were not inspected.
Testing transparency: Pricing-first curated coverage. The bounded September 7 audit found no certificates of analysis, purity results, batch identifiers, laboratory names, or verification codes in Strand Bio’s public research, compliance, and catalog markup. PeptideBenchmark checked 83 reachable pages and fourteen conventional certificate routes; none served a public PDF document. Of 1 exact authentication gate reached from public links, the partner feed returned its reviewed 401 approved-researcher response after the researcher-login route migrated to the public catalog. Otherwise unlabelled image pixels are outside this finding. Detectable testing language on public pages appeared only in reviewed comparison or policy context.
Profile:strand-bio
Open profileA Miami-identified Shopify storefront whose GLP-1 line carries Freedom Diagnostics certificates that resolve independently at the issuing laboratory, attached to a broad openly priced catalog.
Prime Lab Peptides publishes certificates as product-gallery images rather than in a certificate library, and the strongest of them verify at Freedom Diagnostics under the Prime Lab client name. That verified evidence is concentrated on the GLP-1 range; most of the catalog carries vial photography only. PeptideBenchmark normalizes the full peptide range to $/mg, withholds listings the vendor marks unavailable, and separates independently confirmed certificates from named-lab reports that cannot currently be checked.
Testing transparency: Product-gallery COAs with Freedom Diagnostics provider verification. Certificates are attached to product pages as gallery images with no distinguishing filename, so PeptideBenchmark identifies them by reading each image rather than by its name. Freedom Diagnostics certificates are confirmed against the laboratory’s own host under the Prime Lab client name and carry accession, lot, net peptide content and HPLC-UV purity. Janoshik test reports on the same surface state a task number and unique key, but Janoshik answers automated checks with a managed challenge, so those remain named-lab evidence without a provider badge.
Profile:prime-lab-peptides
Open profileA Wyoming-registered WooCommerce storefront with a fully open catalog API and a batch-level certificate library covering nearly every peptide it sells.
BIOLENO publicly lists price, stock, and dosage information, and pairs almost every catalog peptide with a BTLabs batch certificate on its public COA page. PeptideBenchmark normalizes the entire peptide range to $/mg without a deferral and preserves each certificate with its batch identifier, purity, and measured potency. The certificates are named-lab documents rather than independently verifiable reports, and several report a measured quantity outside the specification printed on the certificate itself.
Testing transparency: Public batch COA archive with named-lab BTLabs reports. The public COA page links a batch certificate for nearly every catalog peptide as a signed storage object that requires no account. Every certificate is issued by BTLabs and names BIOLENO as the customer, reporting HPLC purity, HPLC potency, FTIR identity, and appearance. BTLabs publishes no public verification portal, so PeptideBenchmark records these as named-lab vendor-hosted documents rather than provider-verified reports.
Profile:bioleno
Open profileA Wyoming-registered Shopify storefront whose public COA lookup widget exposes 144 index entries, including 141 document-backed certificate records; 113 resolve independently at Freedom Diagnostics, Horizon Analytical, or BioRegen.
Bluum Peptides sits behind an age-gate cookie rather than an account wall — a browser session that clears the gate reads the public catalog and the COA lookup page's embedded lot dataset. PeptideBenchmark currently retains 90 current-batch and 51 historical document-backed records. Of those, 113 resolve independently at Freedom Diagnostics, Horizon Analytical, or BioRegen; the remaining named-lab documents stay visible without an unearned provider-verification badge.
Testing transparency: Public multi-laboratory COA index with exact provider verification. The public /pages/coa-lookup widget exposes 144 index entries; 141 currently have attributable documents and three do not. PB retains 90 current-batch and 51 historical records, hashes and extracts each available document, and distinguishes exact provider verification from a laboratory name printed on a vendor-hosted copy. Freedom Diagnostics and Horizon Analytical records resolve through their public lookups, BioRegen credentials are confirmed at its public report endpoint, and seven historical Janoshik-named images remain named-lab evidence because they were not independently resolved in this pass.
Profile:bluum-peptides
Open profileIncluded because Swiss Chems now has a real structured curated pass: a public peptide storefront with enough visible pricing to normalize a meaningful simple-product slice, plus a broad public Independent Test Results archive and a separate public product-verification gateway.
A meaningful but mixed public-transparency case. Swiss Chems exposes a substantial public testing archive with many vendor-hosted report-image entries across peptide products, and it separately advertises a lot-specific verify-products flow. At the same time, much of the pricing surface still shows price ranges on variable products rather than exact per-option prices.
Testing transparency: Public testing-image archive plus verify gateway. Swiss Chems publicly exposes an Independent Test Results page with many vendor-hosted report-image assets and also a public verify-products gateway that says readers can retrieve batch COA and independent test results with a verification code. That creates a real public trust layer. The current limitation is that we have reviewed the public gateway form itself but have not yet completed a successful lookup through it, so the archive is the stronger currently inspectable evidence tier.
Profile:swiss-chems
Open profileIncluded because TCore now has a real public curated pass: a browsable WooCommerce shop with live product-page variation pricing, plus repeated public Certificate of Analysis signals directly on product pages.
A solid vendor-hosted transparency case. TCore exposes a public storefront with inline variation pricing on variable products, and many product pages directly embed COA images inside the main product gallery instead of limiting trust language to generic claims.
Testing transparency: Public product-page COA gallery pattern. TCore embeds COA images directly in the WooCommerce product gallery, and every sampled certificate is issued by Vanguard Laboratory, an ISO 17025:2017 / A2LA-accredited US lab (Certificate #6377.01.01), reporting HPLC-UV chromatographic purity (~99.6% average) plus a measured mg quantity per vial. That is a named accredited third-party lab, not a bare testing claim, though the certificates are hosted on the TCore domain rather than looked up through a lab-run portal.
Profile:tcore-biotech
Open profileIncluded because Vital Core Research has a public Woodmart/WooCommerce storefront with live variation pricing and product-gallery COA image assets following a consistent VCR-COA naming pattern.
A public storefront with live variation pricing and COA images embedded directly in the product gallery. A consistent COA naming convention makes trust evidence easy to spot across the catalog.
Testing transparency: Public product-gallery COA image pattern. Vital Core embeds COA images across its product gallery, and sampled certificates come from two named accredited labs: MZBiolabs (HPLC-UV-MS purity plus mass-spectrometry identity, often a two-page certificate) for SARMs, and Vanguard Laboratory (ISO 17025 / A2LA) for peptides, averaging ~99.4% purity across 51 COA-covered products. Vanguard runs a public COA-verification database (verifiedbyvanguard.com), but Vital Core’s reports are not in it — the brand has not opted into Vanguard’s public data-sharing, so its Vanguard COAs cannot yet be pulled independently from the lab. Named third-party labs, not bare claims, though the certificates are currently vendor-hosted images.
Profile:vital-core-research
Open profileIncluded because Vortex Research has a public WooCommerce storefront with simple-product pricing and prominent Certificate of Analysis language emphasizing independent ISO-accredited lab testing on every batch.
A focused 18-product catalog with a "COA Verified" badge on every product, though only a small subset currently has downloadable Freedom Diagnostics certificates — the rest have shown "COA Coming Soon" since June 2026.
Testing transparency: Freedom Diagnostics COAs (rollout stalled). Vortex Research uses Freedom Diagnostics for independent testing, with COAs accessible via a modal on each product page. As of July 2026, 2 of 18 products have published COAs — unchanged since June despite the vendor's "COA Coming Soon — ETA: 2 weeks" label on the rest. Accession codes on published certificates are verifiable at freedomdiagnosticstesting.com.

Open profileIncluded because Ascension Peptides has a public storefront with openly visible pricing, branded GLP labels, and COA language on the public site.
A mid-sized catalog with branded labels (R-30, T-30, C-10, S-5) and standard peptide offerings. Public storefront with openly visible pricing.
Testing transparency: Kovera Labs provider verification. Ascension publishes a public COA archive whose certificates resolve to Kovera Labs (live-verifiable at koveralabs.com) across all 75 reviewed products, at ~99.6% purity with deep panels (HPLC, identity, endotoxin, sterility, heavy-metals, net-content); a subset are MZ Biolabs. This is provider-verifiable third-party evidence, not the text-only callouts we first recorded.

Open profileIncluded because Atomik Labz combines a large public catalog with broad product-level testing-document coverage and independently checkable Janoshik reports.
A large-catalog vendor with strong benchmark coverage and competitive pricing on core peptides and GLP-style listings. Its public product galleries expose 546 current vendor-published document images across 216 of 236 reviewed product listings; 104 current report images check out through Janoshik task-and-key links.
Testing transparency: Per-product testing gallery with 104 current Janoshik lookups. Atomik Labz associates vendor-published testing images with a broad portion of its product catalog. In the current reviewed set, 104 report images have task-and-key links that resolve on Janoshik's public verify page. Four older Janoshik lookups remain in the historical archive and are not counted as current. PB treats the remaining current images as vendor-published documents unless the document itself establishes an exact laboratory or provider identity; filenames, layout, and logos alone do not receive a provider badge.
Profile:atomik-labz
Open profileIncluded because Bio Edge has a large peptide catalog with a Certificate of Analysis published on every product page, most of them third-party lab reports that can be independently verified.
A wide catalog that pairs each product with a public Certificate of Analysis — third-party reports from Kovera Labs and MDx BioAnalytical Laboratory, plus Freedom Diagnostics and Janoshik Analytical, with many products showing several lots. Reported purity averages around 99.7% and most reports carry endotoxin, heavy-metals, or sterility panels alongside HPLC and identity.
Testing transparency: Third-party Kovera Labs and MDx COAs with public provider verification. Bio Edge shows a Certificate of Analysis on every product, and most can be confirmed at the issuing lab rather than taken on the vendor’s word: Kovera Labs reports resolve by their KVR code on Kovera’s public lookup, and MDx BioAnalytical Laboratory reports resolve by their COA identifier on MDx’s public CoA Search. Freedom Diagnostics (public accession lookup) and Janoshik reports appear as well. Roughly nine in ten of the certificates carry a live provider-verification link, which is broad, provider-verifiable public evidence rather than generic purity language.
Profile:bioedge-research-labs
Open profileIncluded because Peptide Sources publishes a broad product catalog with third-party certificates attached across most of its product pages.
A broad catalog with 126 public certificate-to-product relationships spanning 119 of 159 reviewed products and representing 125 distinct source images. Most reports name Freedom Diagnostics or Bioviridian, average about 99.5% reported purity, and expose a public provider-verification path.
Testing transparency: Broad third-party COAs with public provider verification. Peptide Sources publishes 126 certificate-to-product relationships across 119 of 159 reviewed products, representing 125 distinct source images. Of those, 113 are provider-verifiable relationships (112 distinct images): 70 Freedom Diagnostics reports with a public Search Code, 42 Bioviridian reports whose printed codes resolve to laboratory-hosted certificates, and one Chromate report verified with its two-part public lookup. The remaining 13 relationships are kept as named-lab documents rather than upgraded beyond what their verification path supports.
Tracked under the current dataset name "Peptides Source."

Open profileIncluded because Nura Peptide has a public storefront with openly visible pricing, branded product naming conventions, and COA language on the public site.
A mid-sized catalog with branded labels (GLP-3R, GLP-2T, GLP-1SG) spanning vials, nasal sprays, and capsules, backed by an unusually deep set of third-party Freedom Diagnostics COAs embedded across the product gallery.
Testing transparency: Third-party Freedom Diagnostics COAs with public provider verification. Nura embeds third-party Freedom Diagnostics COAs across its product gallery. PB currently retains 87 distinct certificate origins related to 40 products: 86 resolve through exact Freedom provider routes and one remains a source-linked vendor document. The current evidence reports HPLC and identity broadly, net content on 86 product-certificate relationships, and endotoxin on 36; no current sterility or heavy-metals panel is inferred where the documents do not report one.

Open profileIncluded because Pepora Labs runs a public storefront with openly visible pricing and exposes Freedom Diagnostics accession-verifiable COAs for its core range — an independent-provider lookup, stronger than downloadable PDFs or purity claims alone.
A small, focused catalog of single peptides plus branded blends (KLOW, GLOW, Wolverine, GLP-3). Dosage is encoded in the product SKU rather than the title. The four highest-volume products (GHK-Cu, TB-500, Tesamorelin, Retatrutide) publish a Freedom Diagnostics batch accession and exact purity (~99.7%, HPLC + mass-spec identity) right in the product-page testing box, each searchable at FreedomDiagnosticsTesting.com.
Testing transparency: Freedom Diagnostics provider verification. Pepora’s core range carries Freedom Diagnostics accession-verifiable COAs — the batch accession, exact purity, and HPLC + mass-spec panels are exposed in product-page HTML with a public FreedomDiagnosticsTesting.com lookup. That is provider-verifiable public evidence, not just vendor-hosted documentation. The catalog is small, so this covers 4 of ~11 products; the rest rely on product-page testing language.

Open profileIncluded because Glacier exposes both a public product catalog and a structured public COA archive — enough real evidence to compare it directly, after earlier confusion caused by a look-alike domain.
A stronger case than it first appeared. Glacier’s storefront routes visitors through a research-access gate, but its public COA archive holds per-lot Kovera Labs and Freedom Diagnostics reports — 70 of them independently verifiable at the testing lab, averaging 99.7% purity with near-complete safety-panel coverage.
Testing transparency: Per-lot Kovera Labs & Freedom Diagnostics COAs with public provider verification. Glacier publishes a structured public COA archive (lot/date-level PDFs) whose reports are third-party — Kovera Labs (KVR verification code) and Freedom Diagnostics (public accession lookup). 70 lots carry a code that resolves on the testing lab’s own public verify surface, so this is outside-provider verification, not just vendor-hosted documentation. Average verified purity is 99.7% and nearly every report runs the full safety panel (endotoxin / sterility / heavy metals).

Open profileIncluded as VAYN (rebranded from His & Hers). Public storefront at vayn.co with live product pricing and a public /coas/ archive.
Rebranded from His & Hers to VAYN with the same products and formulas. Now at vayn.co with a clean public storefront and a public /coas/ archive — one page per batch. About half the archive is live-verified Chromate (RP-HPLC purity + identity); most of the rest resolves as Freedom Diagnostics provider objects with purity, identity, and net content. Reported purity averages around 99%.
Testing transparency: Public COA archive with Chromate and Freedom provider verification. VAYN publishes a public /coas/ index of batch-level pages. Forty-five retained reports identify Chromate and 39 identify Freedom Diagnostics; 84 certificate origins currently resolve through provider-controlled routes. Most documents report purity and identity, Freedom reports also carry net-content results, and three certificates report endotoxin. No current sterility or heavy-metals panel is inferred where a document does not report one.

Open profileIncluded because Ignite Peptides has a public storefront with openly visible pricing, branded GLP labels (GLP-1 (S), GLP-2 (TZ), GLP-3 (RT)), and a public COA Library of third-party Janoshik and Freedom Diagnostics reports.
A broad peptide catalog with branded GLP naming and core research peptides. Ignite publishes a dedicated public COA Library of third-party lab reports — mostly Janoshik Analytical (HPLC purity) with some Freedom Diagnostics — alongside product-gallery COA images.
Testing transparency: Public COA Library with Janoshik provider verification. Ignite publishes a public COA Library of third-party reports. Its Janoshik certificates now deep-resolve at verify.janoshik.com (the report’s task number + on-report unique key), so each one opens the actual report in one click rather than a portal search — 11 verify this way, plus Freedom Diagnostics accessions and a Kovera Labs report. Reports back roughly half the injectable catalog; the rest ship without a public certificate.

Open profileIncluded because Pepvida is a Canada-based storefront with a small, fully-priced catalog, branded product naming (RESET / HEAL / ATTRACT), and downloadable per-product COA PDFs with real purity figures.
A compact 9-product catalog with branded naming and dosages in the product titles. Pepvida is Canada-based (Ontario), ships to the US and Canada from Canadian warehouses, and lists prices in Canadian dollars — the pricing board converts those to USD so the comparison is apples-to-apples. Downloadable COA PDFs are published on a public lab-results hub.
Testing transparency: Testides provider verification COAs. Pepvida publishes downloadable COAs on a public lab-results hub, and the sampled certificates resolve to Testides — a third-party provider that hosts exact report pages and linked PDFs on its own domain (testides.com/report/{code}) at ~99.5% purity — rather than the unnamed vendor-hosted documentation we first recorded. PeptideBenchmark confirms the report identity and provider-served PDF before recording the relationship as independently checkable.

Open profileIncluded because Regenerative Research pairs a clean headless storefront (live price and mg dosage exposed per product) with a downloadable third-party Certificate of Analysis on every peptide, a portion of them carrying independent provider verification.
A focused peptide catalog on a modern headless storefront with transparent per-mg pricing, and a per-batch Certificate of Analysis linked to every product — a mix of Krause Analytical, ILS Laboratories, Freedom Diagnostics, and BTLabs reports covering purity, identity, endotoxin, sterility, and heavy metals.
Testing transparency: Per-product third-party COAs, some with public provider verification (ILS Laboratories, Freedom Diagnostics). Every peptide links a downloadable third-party COA reporting HPLC purity, identity, endotoxin, sterility, and heavy metals, plus a controlled-substance contaminant screen. The lab mix is uneven: many certificates are vendor-hosted PDFs from named labs (Krause Analytical, BTLabs), while ILS Laboratories COAs (access code independently verifiable at ils-lab.com) and Freedom Diagnostics (public accession) are provider-verifiable.

Open profileA broad WooCommerce storefront that pairs a large research-peptide catalog with a per-product third-party COA gallery — HPLC purity plus USP safety panels on nearly every product.
One of the wider curated catalogs — branded GLP agonists across many dosages, recovery blends, and a full run of Khavinson bioregulators — where each product ships its own gallery of third-party COA images from Vanguard Laboratory (ISO 17025 HPLC-UV/VIS purity + quantity) and Janoshik Analytical, alongside USP <85> endotoxin and <71> sterility panel scans. Purity runs consistently high and safety-panel coverage is unusually complete.
Testing transparency: Per-product third-party COA gallery (Vanguard / Janoshik) with USP safety panels. Every in-scope product publishes a gallery of third-party COA images: Janoshik Analytical and Vanguard Laboratory HPLC-UV/VIS purity and quantity reports plus USP <85> endotoxin, <71> sterility, and <61> microbial panel scans. Each Janoshik report names a unique key that readers can check at janoshik.com/verify, while the Vanguard COAs are named accredited-lab documents without a public verification portal.

Open profileA registration-gated storefront that nonetheless publishes a fully public /lab-results/ COA library — most of it backed by two independently verifiable third-party labs (Janoshik Analytical and Chromate), paired with transparent per-mg pricing.
One of the deeper public certificate trails in the catalog: a /lab-results/ library of 126 distinct COAs across the range, the majority carrying either a Janoshik Analytical “TEST REPORT” or a Chromate certificate that resolves two-factor at the lab’s own portal. Reported purity averages about 98%, with endotoxin, sterility, and heavy-metals panels appearing on a meaningful share of certificates. A further tranche of products publishes vendor-hosted Vanguard Laboratory COAs as named-lab evidence.
Testing transparency: Third-party Janoshik + Chromate COAs with public provider verification. RUO’s public /lab-results/ library links per-product COAs from Janoshik Analytical and Chromate. Each Janoshik report carries a task number plus a unique key that resolves two-factor at verify.janoshik.com, and each Chromate certificate carries a job number plus an access code that resolves at chromate.org — 82 certificates across the catalog were confirmed live at the provider before being recorded, so they can be checked at the lab rather than taken on the vendor’s word. Some products additionally publish a vendor-hosted Vanguard Laboratory COA; those are counted as named-lab evidence, not provider-verifiable, because Vanguard does not expose a public report-lookup portal.
A registration-gated storefront that nonetheless publishes one of the deepest public COA archives in the catalog — hundreds of TrustPointe Analytics Certificate-of-Analysis reports, the recent batches independently verifiable at the lab's own portal — paired with transparent per-mg pricing.
A broad injectable peptide catalog backed by a public WordPress lab-report archive of several hundred TrustPointe Analytics COAs, one per batch. Every certificate prints a TrustPointe Verification Key, and recent batches resolve live at trustpointelims.com, so a reader can confirm the report at the lab rather than taking the vendor's word. Reported purity runs near 99.7%, with endotoxin screening published per batch.
Testing transparency: Third-party TrustPointe Analytics COAs with public provider verification. Skye publishes a public lab-report archive whose COA PDFs are TrustPointe Analytics reports; each prints a Verification Key that resolves at trustpointelims.com. The recent batches were confirmed live at the portal before being recorded as provider-verifiable — the report is reached at the lab, not just hosted by the vendor. Older batches rotate out of the public portal but remain published as named-lab TrustPointe documents, and the verified share grows weekly as new batches are checked.

Open profileA Las Vegas storefront that backs essentially its entire catalog with third-party Freedom Diagnostics COAs — every certificate independently confirmable at the lab, at near-99.7% reported purity — paired with transparent per-mg pricing.
A broad injectable peptide catalog where each product links a downloadable Freedom Diagnostics Certificate of Analysis carrying a public Accession # and Search Code. Every certificate was two-factor confirmed — the vendor's copy is matched against Freedom's own portal record, with the client, search code, accession, and lot cross-checked between the two (and nearly all are byte-identical) — so a reader can verify the report at the lab rather than trusting the vendor's upload. Reported purity runs near 99.7%, with identity, net-content, and endotoxin results published per batch.
Testing transparency: Per-product Freedom Diagnostics COAs with public provider verification. Protide publishes a per-product COA archive whose certificates are Freedom Diagnostics reports; each prints an Accession # and Search Code that resolve at FreedomDiagnosticsTesting.com. Every certificate was confirmed live against the provider's own copy before being recorded as provider-verifiable — the report is reached at the lab, not just hosted by the vendor. The current set reports identity, HPLC purity, net content, and frequent endotoxin results; two current reports also include heavy-metals results, while panel coverage remains certificate-specific.

Open profileA WooCommerce storefront whose tested products carry downloadable third-party COAs from two independently queryable labs — Horizon Analytical and ILS Laboratories — every certificate confirmable against the issuing lab under the Northline Labs client name, at ~99.3% reported purity.
Most of the injectable catalog links a downloadable Certificate of Analysis issued by one of two third-party labs. Horizon Analytical reports (purity by UPLC/MS plus a separate endotoxin certificate) resolve by lot number at horizonanalytical.com; ILS Laboratories reports (HPLC purity and identity, net-peptide content, and endotoxin) resolve by COA number at ils-lab.com. Every certificate was two-factor confirmed — the vendor's lot or COA number is resolved against the lab's own public record and the returned client name is matched to Northline Labs — so the report is reached at the lab, not just hosted by the vendor. Reported purity runs near 99.3%.
Testing transparency: Per-product Horizon Analytical and ILS Laboratories COAs with public provider verification. Tested products link a vendor-hosted COA PDF issued by Horizon Analytical or ILS Laboratories. Each Horizon lot (NLL-…) is searchable at horizonanalytical.com and each ILS COA number resolves at ils-lab.com; both return the report under the Northline Labs client name, so a reader can confirm the certificate at the issuing lab rather than trusting the vendor's upload.

A public WooCommerce catalog where product pages carry per-product Vanguard Laboratory COA images reporting HPLC purity plus endotoxin, sterility, and heavy-metals panels. What lifts it above vendor-hosted documents is that the same Vanguard report IDs are published to Vanguard’s own public COA portal, so a reader can pull the certificate straight from the lab rather than trusting a vendor-hosted image.
Testing transparency: Vanguard Laboratory COAs with public provider verification. Licensed Peptides embeds per-product Vanguard Laboratory COA images (HPLC chromatographic purity near 99.5%, with endotoxin, sterility, and heavy-metals panels on many batches) and publishes the same certificates to Vanguard’s public COA portal (verifiedbyvanguard.com) under the brand it registered there, so the report IDs resolve to lab-hosted PDFs a reader can verify independently. Vanguard is an ISO 17025:2017 / A2LA-accredited US laboratory (Certificate #6377.01.01).

The Peptides Collective publishes an openly priced research-peptide catalog and a public Lab Reports grid of batch cards with downloadable COA PDFs. Branded GLP aliases (GLP-3/R, GLP-1/S, GLP-2/T) map to retatrutide, semaglutide, and tirzepatide for $/mg comparison; named blends such as KLOW, GLOW, Selank+Semax, and Ipamorelin+Tesamorelin use their labeled vial totals. Most certificates are Janoshik Analytical TEST REPORTs; a Chromate subset prints job and access codes for independent portal checks when the provider resolves.
Testing transparency: Public Janoshik + Chromate COA archive with provider verification. The public /lab-report/ page lists batch cards with purity, lot, date, and View COA PDF links under wp-content/uploads. Credentials are read from each PDF and confirmed at Janoshik or Chromate when the portal accepts the pair; documents that name a lab but do not currently resolve stay as named-lab, vendor-hosted evidence rather than provider-verified.

Open profileA West Hollywood, California storefront built as a custom app rather than Shopify or WooCommerce, whose product bundle and public /coas page carry 35 recoverable Freedom Diagnostics COA PDFs — 33 of them resolving independently at the lab's own public lookup.
SKO Compounds sits behind a 21+/research-use overlay that gates the rendered page but not the underlying data: the site's own content-hashed JavaScript bundle embeds the full 33-product catalog (name, dosage ladder, per-dosage price, stock, and COA PDF path), and a public Supabase RPC exposes live stock overrides — both readable with a plain unauthenticated fetch. PeptideBenchmark normalizes 29 in-stock dosage rows to $/mg and processed all 35 recovered COA PDFs (25 current-batch, 10 retained prior-batch): every one carries a FreedomDiagnosticsTesting.com letterhead, and 33 verify independently under the SKO Compounds client name at the lab's own public certificate lookup. 11 products are marked "Coming Soon" on SKO's own /coas page and are recorded as an explicit testing gap rather than silently dropped.
Testing transparency: Freedom Diagnostics COAs with public provider verification. Every COA PDF URL is read directly out of SKO's own product bundle (current and retained prior-batch fields), downloaded, and text-extracted rather than guessed from a gallery image. Of 35 recovered Freedom Diagnostics PDFs, 33 resolve live at the lab's public lookup under the "SKO Compounds" client name, reporting HPLC purity (averaging about 99.7%), identity, net content, and endotoxin on applicable batches. Two older Freedom documents no longer resolve and remain named-lab evidence. A separate current Kisspeptin certificate names ILS Laboratories and reports identity, purity, net content, endotoxin, sterility, and heavy metals; because it has no confirmed provider route, those panels remain document-extracted rather than provider-verified.

Those documents resolve at named labs (Janoshik, Freedom, MZ Biolabs, Waiida) but currently print OEM/wholesale client names rather than Core Research Peptides — a different company from curated Vital Core Research.
Core Research Peptides sells a compact research-only catalog with prices on the product pages, including two Retatrutide strengths and common singles. Its public COA library hosts downloadable laboratory PDFs. PeptideBenchmark opens those files and checks Janoshik task/key routes and the Freedom index where codes exist; the reports’ own client fields name other accounts, so they stay named-lab public documents rather than vendor-client–matched verification. Reconstitution solution stays off the peptide $/mg board; hCG is IU-labeled and deferred.
Testing transparency: Public COA archive. The public COA library hosts vendor-hosted laboratory PDFs that readers can download. Janoshik task/key pairs and a Freedom Search Code can be checked at those laboratories’ public surfaces, but the printed client names are OEM/wholesale accounts rather than Core Research Peptides. Library rows still marked pending are recorded as testing gaps. A matched document describes the tested sample and does not endorse every vial or unlisted safety panel.

Nation Peptides sells research-only singles and blends with prices listed on the product pages, including branded GLP-1/2/3 strengths and a Glow blend. Its public COA page hosts Freedom Diagnostics–labeled certificates for much of the peptide range. Those documents resolve on Freedom’s public index, but they are filed under generic wholesale client names (not Nation Peptides), so PeptideBenchmark treats them as named-lab public documents rather than vendor-client–matched verification.

Blue Ridge Peptides sells research-only singles and blends with prices on the product pages, including house codes BRP-1S / BRP-2T / BRP-3R for semaglutide, tirzepatide, and retatrutide, plus GLOW/KLOW and a Wolverine-style BPC/TB blend. Its public media library and product galleries currently retain 69 Freedom Diagnostics certificates and one Kovera Labs certificate. HTML shop routes are age-gated; prices and certificates remain publicly checkable.
Testing transparency: Public Freedom Diagnostics and Kovera provider verification. Certificate PDFs are publicly linked from product galleries and the WordPress media library. Sixty-four current report origins resolve through provider-controlled routes, while six vendor-hosted images or PDFs remain source-linked without an independent-verification badge. The retained documents broadly report identity, HPLC purity, and net content; one Kovera report additionally carries endotoxin, sterility, and heavy-metals results, which PB keeps specific to that certificate rather than applying across the catalog.
