Vendor Rankings

Peptide Partners

Curated

Included as part of the core shortlist of names repeatedly mentioned in research-vendor circles.

Now one of the strongest public-testing-transparency cases in the curated set because its Independent Certifications page exposes a large vendor-hosted archive spanning multiple certification categories and multiple named outside labs.

Testing transparency: Public multi-lab certification archive. Peptide Partners publicly exposes an Independent Certifications archive with downloadable vendor-hosted files across purity, endotoxin, heavy metals, and sterility. The archive directly names outside labs including TrustPointe, Kovera, Chromate, and BioRegen, which makes this a stronger public evidence pattern than generic lab-testing language alone.

Crush Research

Curated

Included as a recognizable research-vendor name with enough community familiarity to merit focused tracking.

Now one of the stronger curated testing-transparency cases because its public testing page exposes structured batch metadata, public COA PDFs, and named outside lab attribution rather than just generic quality language.

Testing transparency: Public testing index with vendor-hosted COA PDFs. Crush Research exposes a public `/testing` page with structured batch rows, vendor-hosted COA PDFs, and named outside labs including Freedom Diagnostics, BTLabs, and ILS Laboratories. That is a stronger public-evidence pattern than generic “COA available” claims, even though the files still live on the vendor domain.

Polaris Peptides

Curated

Included as a known community name we may want to compare against the broader benchmark set over time.

Still useful as a comparison name, and the public site now looks more structured than it first appeared because it exposes real sitemap-backed product surfaces even while the delivered homepage experience stays account-forward.

Testing transparency: Public sitemap with account-forward storefront. Polaris publicly exposes a sitemap index with product and product-category sitemaps, which is a meaningful catalog-transparency signal. At the same time, the delivered homepage and broader storefront feel account-forward, so the current read is stronger on catalog visibility than on openly inspectable COA or testing documentation.

Kimera Chems

Curated

Included in the shortlist as a recognizable research-vendor name with public COA evidence and a now-live tracked profile.

Interesting less for public location clarity and more for the layered transparency pattern: repeated public COA links and COA-style image assets on product pages, plus vendor-hosted documents that identify outside testing work.

Testing transparency: Public COA page plus provider-authored reports. Kimera product pages repeatedly expose a public `COA` link and, in many sampled cases, COA-labeled image assets directly on the vendor domain. Separate vendor-hosted PDFs identifying TrustPointe Analytics as the issuing lab add a second transparency signal, even though this is still different from a provider-run live verification portal.

Blank Peptides

Curated

Included because it is part of the manually selected research-vendor watchlist, even though the current dataset name is shorter.

Now a meaningful public-transparency case because its product pages expose a structured public COA preview grid with repeatable purity and endotoxin document links across the catalog.

Testing transparency: Public product-page COA grid. Blank product pages expose a visible COA section with repeatable public document links, including purity COAs and, on many products, endotoxin files. That is a stronger open pattern than generic “COA available” copy, even without an outside verification host. At the same time, 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 to it in the materials we have reviewed.

Tracked under the shorter dataset name "Blank."

Peptide Supply Co

Curated

Included in the curated queue as a community-known research vendor with visible testing language and a currently gated lab-results flow.

Worth tracking because it pairs community familiarity with visible lab-results language and direct support/contact signals.

Testing transparency: Gated certificate library. The public site advertises lab results and testing, and authenticated review confirms a substantial vendor-hosted certificate library after login. Publicly, though, this still behaves as a gated lab-results flow rather than an openly browseable evidence layer.

Elite Research USA

Curated

Included as a recognizable U.S.-based research-vendor name in the current focus set.

Worth tracking because the public site exposes a real catalog surface and strong operator claims around testing, and authenticated review now confirms a deeper gated certificate layer behind that login-first flow.

Testing transparency: Public product sitemap with gated product browsing. Elite Research USA publicly exposes a product sitemap and a visible research-compound catalog, which is stronger than a fully opaque storefront. Authenticated review now confirms that the login-first experience does unlock a real gated certificate layer, including multiple certificate-image routes served from the vendor’s public S3 bucket. Publicly, though, this still remains a gated product/COA pattern rather than an openly inspectable certificate archive.

Pure Peptides

Curated

Included 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.

The public site names MZ Bio Labs as its independent testing lab, and the product sitemap exposes a repeatable public COA/MS/endotoxin image layer across a meaningful part of the catalog.

Testing transparency: Public sitemap-derived COA / MS / endotoxin image layer. Pure Peptides publicly names MZ Bio Labs as its third-party testing partner — the homepage states every lot is independently tested for purity, quantity, and endotoxins before release — and the public product sitemap confirms a real document layer rather than just marketing copy: dozens of COA-, MS-, and endotoxin-labeled image assets exposed on the public domain. That is a materially stronger signal than disclosure language alone, even though the current evidence still looks more like a vendor-hosted image/document layer than a provider-run verification archive.

Tracked under the current benchmark dataset name "Pure Peptides Bio."

Peptide Plugs

Curated

Included 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."

Simple Peptide

Curated

Included as a priority research-vendor profile and now also useful for testing-evidence workflow expansion.

One of the best shortlist candidates for testing-transparency work because its catalog exposes repeated public COA archive paths across a large product set.

Testing transparency: Vendor-hosted public COA archive. Simple Peptide exposes repeatable public COA archive paths across many product pages, which makes it one of the cleaner vendor-hosted transparency patterns in the current curated set.

Orbitrex Peptides

Curated

Included 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 links that route into Kovera, Chromate, TrustPointe, and publicly accessible Dropbox-linked certificate files. That is a materially stronger public transparency pattern than generic “third-party tested” copy alone, even though the archive still mixes provider-hosted links and vendor-linked public documents.

Evolve Peptides

Curated

Included as an active name in the curated watchlist and already connected to a live vendor profile.

Now a stronger transparency candidate than the more account-forward storefronts because its public site exposes both a browseable shop surface and a dedicated public test-results page with a mix of vendor-hosted report assets and some direct public Janoshik links.

Testing transparency: Public test-results page with mixed vendor-hosted and Janoshik evidence. Evolve publicly exposes a `/test-results/` page and a public shop/storefront surface rather than forcing users into a login-first catalog. The current public evidence layer includes many vendor-hosted COA/report-style assets on the Evolve domain, plus some direct Janoshik report links from the public test-results page. That combination is stronger than generic testing language alone, even though much of the catalog still surfaces through vendor-hosted documents rather than a whole-catalog third-party verification flow.

Oath Research

Curated

Included in the current focus set as a now-mapped research vendor with a public rebrand and address trail.

Especially useful for the curated list because the rebrand, public contact trail, and repeated product-level certificate links make it a strong next testing-evidence candidate.

Testing transparency: Vendor-hosted public lab-result pages. Oath exposes repeated product-level certificate links that resolve to vendor-hosted lab-result pages, plus a public lab-results index, which makes it a strong public-transparency case even without a third-party verification host.

Verified Peptides

Curated

Included 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.

Stronger than a generic COA claim: Verified Peptides publicly exposes a large lab-reports archive with batch-level summaries, purity figures, and linked report pages across a broad portion of the catalog.

Testing transparency: Public lab-reports archive. Verified Peptides publicly exposes a lab-reports page that describes an archive of 400+ published peptide lab reports and shows batch-level purity, weight, endotoxin, and in some cases sterility details with linked report pages. That is a materially stronger public transparency pattern than vague “third-party tested” language, even though it still looks primarily vendor-hosted rather than provider-controlled.

Paramount Peptides

Curated

Included 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: Public searchable COA lookup. Paramount publicly exposes a searchable COA lookup by product name or lot number. The current review pass found repeated public result rows with lot numbers, analysis dates, and vendor-hosted COA image assets, plus a broad public product sitemap. That is materially stronger than generic COA marketing language, even though the evidence currently routes into vendor-hosted COA images rather than outside-provider verification pages.

Mile High Compounds

Curated

Included 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 exposes a real public product sitemap with many report-like COA image assets, and authenticated review confirmed the full catalog behind the research-access gate is real.

Testing transparency: Public sitemap COA images + gated full catalog. Mile High routes anonymous visitors into a research-access gate, but the public product sitemap still exposes meaningful testing evidence: dozens of product URLs and report-like COA image assets on the vendor domain. Authenticated review confirms that the full product catalog is real after login, which makes Mile High stronger than a purely opaque gated storefront even though the most inspectable evidence still lives in vendor-hosted public images rather than provider-controlled verification.

Forge Performance Co.

Curated

Included 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 COA-on-every-batch claims are all visible on the public site.

Testing transparency: Public COA-backed storefront claims. Forge publicly presents itself as a Texas-based, independently operated research vendor with certificate-of-analysis documentation on every batch and COA-backed best sellers. That is stronger than a bare product catalog, but we have not yet confirmed a broad public archive or outside-provider-linked verification layer.

Puratek Peptides

Curated

Included 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: Public certifications archive. The structured public pass confirmed both a live `/coa/` page and a broader public `/certifications/` archive of vendor-hosted batch-report images. The certifications page publicly describes those reports as third-party verified purity reports from Freedom Diagnostics, and at least one report in the archive is ILS Laboratories-branded. That is materially stronger than generic storefront COA language, even though the current evidence is still image/archive based rather than a provider-controlled verification portal.

GenPeptide

Curated

Included 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.

Potentially one of the most interesting new additions: the public site names Freedom Diagnostics and Chromate, exposes a View All COAs path, and shows batch-level tested examples directly on the homepage.

Testing transparency: Public COA path with named outside labs. GenPeptide publicly names Chromate and Freedom Diagnostics as testing partners, exposes a `View all COAs` path, and shows concrete batch-level tested examples with dates, batch IDs, and linked reports on the public site. That is substantially stronger than generic third-party testing language and makes GenPeptide one of the more promising next full trust-review candidates.

Tracked under the current benchmark dataset name "Genpeptide."

Ion Peptides

Curated

Included 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.

Ion publicly surfaces COA navigation, “View Lab Test Results,” QR-and-batch-verified positioning, and a more developed quality-assurance explanation than many smaller peptide sites.

Testing transparency: Public COA navigation and lab-results entry point. Ion publicly exposes a `COA` navigation path and a `View Lab Test Results` entry point, while also describing QR-and-batch-verified COA documentation, HPLC, and mass spectrometry in its quality-assurance copy. That is enough to justify curated inclusion, but a deeper review is still needed to determine whether the lab-results layer is broadly public, thin, or partly performative.

NextGenPeps

Curated

Included because it is a U.S.-listed research vendor already on the board and now part of the active affiliate/curated comparison set.

Now a real public-evidence curated case rather than a placeholder hold. The site exposes a public COA library plus product-level public test PDFs across the full currently discovered catalog.

Testing transparency: Public COA library with product-level test PDFs. NextGenPeps publicly exposes a COA library and repeated product-level `Download Tests` / `View online` links that resolve to vendor-hosted test PDFs on the public domain. In the current review pass, all 39 discovered product URLs had certificate signal, which makes this materially stronger than a generic “COA available” claim even though the current evidence still lives on the vendor domain rather than through a provider-controlled verification layer.

Peptime

Curated

Included because it is already benchmarked, exposes a clean public product API, and currently shows at least some direct external COA links from the live product-detail surface.

Peptime is structurally cleaner than many smaller storefronts: the product catalog is exposed through a public API, and at least some live product pages visibly route users to external COA links instead of only making generic purity claims.

Testing transparency: Public API catalog with narrow external COA links. Peptime publicly exposes a machine-readable product catalog through its site API, and the live product-detail frontend currently includes direct external COA links for at least some SKUs. That is a real public signal, but it is much narrower than a broad archive or repeated provider-controlled verification pattern.

Included 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 is no longer just a watchlist add. The storefront publishes simple-product pricing openly, and the public COA page provides a real archive of vendor-hosted report images with direct View COA links across a meaningful slice of the catalog.

Testing transparency: Public COA archive with vendor-hosted report images. Ameano’s strongest current public signal is its dedicated COA archive page, which publishes direct report-image links for many products. That is materially better than generic purity language alone, but it still lives on the vendor’s own domain rather than a provider-controlled live verification portal. The storefront also explicitly marks some pre-sale items as pending COA, which is useful context rather than something to hide.

American Peptide Research

Curated

Included because APR now has a clean public WooCommerce catalog plus repeatable vendor-hosted COA image coverage on a meaningful slice of product pages, which is enough to compare honestly without pretending it is a provider-run verification system.

A practical public-transparency case rather than just a watchlist vendor. American Peptide Research publishes an openly browsable simple-product catalog, and a meaningful subset of public product pages includes embedded COA images directly in the gallery.

Testing transparency: Public API catalog with vendor-hosted COA images. APR’s strongest public signals today are its machine-readable WooCommerce catalog and the repeatable vendor-hosted COA images embedded on many public product pages. That is materially better than generic purity language alone, but it remains vendor-domain documentation rather than provider-controlled live verification.

Amino Club

Curated

Included because it now has live pricing and a meaningful public trust sample worth comparing: the catalog is public after the research gate, and confirmed product pages expose embedded batch-level QC detail rather than only generic purity language.

A more interesting trust case than a normal login-first storefront. After the research gate, Amino Club product pages can publicly expose embedded Certificate of Analysis panels with batch-level purity, identity, heavy metals, sterility, and endotoxin fields right on the page, even though our review has only been able to confirm part of the catalog so far.

Testing transparency: Representative public sample confirmed. Amino Club’s strongest current public signal is not a separate provider-run archive. It is the confirmed embedded Certificate of Analysis panel on public product pages after the research gate is acknowledged, including visible batch-level fields for purity, identity, heavy metals, sterility, endotoxin, lot number, and tested date. Because we have only been able to confirm a sample of product pages so far, the current trust layer should be read as meaningful partial confirmation rather than a finished whole-catalog verdict.

Included 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.

Nationwide Peptides

Curated

Included because Nationwide is now a disclosed affiliate relationship and also exposes both a public WooCommerce storefront structure and repeated public product-page COA links, which makes it honest to compare in the curated layer rather than leaving it as a relationship-only vendor.

A cleaner public-transparency case than a generic peptide storefront. Nationwide exposes a public WooCommerce catalog with machine-readable products, live variable-product pricing on product pages, and direct View Test Report links that resolve to vendor-domain PDF COAs.

Testing transparency: Public product-page COA PDFs plus public catalog. Nationwide’s strongest public signal today is the combination of a public WooCommerce storefront and direct product-page `View Test Report` links that resolve to vendor-domain PDF COAs. The separate public COA page reinforces that this is a real public documentation layer, even though it remains vendor-hosted rather than provider-controlled live verification.

Apex-Peptides.com

Curated

Included 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 its own backend API, an authenticated shop flow, and stable sitemap-backed product routes. Authenticated review now confirms usable product pricing and product-page COA sections behind login, which makes it a real gated comparison case rather than just a placeholder identity.

Testing transparency: Authenticated product-page COA pattern. Apex-Peptides.com publicly exposes a product sitemap and a distinct web-app/backend structure, but the meaningful review surface is behind login. Authenticated review now confirms live product pricing and a Certificate of Analysis section on product pages for selected variants. That is useful gated evidence, while still remaining vendor-hosted and account-gated rather than publicly verifiable by default.

Next Chems

Curated

Included 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.

LA Peptides

Curated

Included because it now has a complete public structured pass: a public product sitemap, live product-page pricing, and a dedicated public /test/ archive.

A solid public transparency case. LA Peptides exposes a broad public storefront with product-page variation pricing and a separate public lab-test archive that repeatedly embeds vendor-hosted COA-style image assets on product-specific pages.

Testing transparency: Public lab-test archive with COA images. LA Peptides currently exposes a public /test/ archive with product-specific entries that embed vendor-hosted COA-style image assets directly on the LA domain. That is stronger than generic product-page testing language alone, even though the evidence is still vendor-hosted rather than provider-run verification.

Swiss Chems

Curated

Included 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.

TCore Biotech

Curated

Included 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 product pages repeatedly state that a Certificate of Analysis is available, and many sampled pages go further by embedding vendor-hosted COA image assets directly in the WooCommerce product gallery. That is a stronger public evidence pattern than a bare testing claim alone, even though it is still vendor-hosted rather than provider-run verification.

Included 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 Research product pages embed vendor-hosted COA image assets directly in the WooCommerce product gallery with a consistent filename pattern. This is a stronger public evidence signal than bare testing claims, though it remains vendor-hosted rather than provider-run verification.

Vortex Research

Curated

Included 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.

IDUN Peptides

Curated

Included because IDUN Peptides has a perfect 10/10 Peptide Critic score and a public COA Library page with extensive certificate-of-analysis documentation.

A focused catalog with competitive pricing, strong COA branding, and a dedicated public COA Library.

Testing transparency: Public COA Library with batch-specific COAs. IDUN Peptides publishes batch-specific COAs via a dedicated /coa-library/ page. Three independent labs used (Kovera Labs, Freedom Diagnostics, FreedomDiagnosticsTesting.com). Average purity 99.6% across reviewed COAs. All tests use HPLC-based methods.

Ascension Peptides

Curated

Included 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: Public COA text callouts. Ascension Peptides references Certificate of Analysis on the public site. Trust evidence is text-based.

Atomik Labz

Curated

Included because Atomik Labz is a consensus-scored vendor with a large catalog (80+ products) and multi-source benchmark coverage.

A large-catalog vendor with strong benchmark coverage and competitive pricing on core peptides and GLP-style listings. Public trust evidence is still thin relative to that pricing coverage.

Testing transparency: Pricing-first curated coverage. Atomik Labz is on the pricing board primarily for price comparison. Its public trust evidence is still thin compared with the archive and verification leaders, and prices here are refreshed less frequently than most vendors.

Bio Edge Research Labs

Curated

Included because Bio Edge has a large peptide catalog with branded GLP labels (EDGE R3, EDGE T2) and competitive MSRP-style pricing.

A substantial catalog of 60+ products with branded naming conventions and competitive pricing. Public trust evidence is still thin relative to that pricing coverage.

Testing transparency: Pricing-first curated coverage. Bio Edge is on the pricing board primarily for price comparison. Its public trust evidence is still thin compared with the archive and verification leaders, and prices here are refreshed less frequently than most vendors.

Peptide Sources

Curated

Included as a community-known research vendor we want to keep visible in the curated layer.

Now a reasonable public-transparency candidate because its public product sitemap exposes at least some explicitly COA-labeled vendor-hosted image assets across product entries.

Testing transparency: Public sitemap-derived COA images. Peptides Source does not yet show the stronger provider-run verification pattern we see on vendors like EZ Peptides, but its public product sitemap exposes a limited set of explicitly COA-labeled vendor-hosted image assets. That is still stronger than generic purity language alone, while remaining narrower than whole-catalog public verification.

Tracked under the current dataset name "Peptides Source."

Included 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) and a mix of vials, nasal sprays, and capsules. Public site references Certificate of Analysis availability and third-party testing.

Testing transparency: Public COA text callouts. Nura Peptide references Certificate of Analysis availability and third-party testing on the public site. Trust evidence is text-based rather than embedded COA images or downloadable certificates.

Pepora Labs

Curated

Included because Pepora Labs runs a public storefront with openly visible pricing and publishes downloadable COA PDFs for part of its catalog, which is more verifiable than 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, and every product page carries ≥99% purity and third-party testing language. Downloadable COA PDFs are published for a subset of products.

Testing transparency: Public product-page COA PDFs. Pepora Labs hosts downloadable Certificate of Analysis PDFs for part of its catalog, linked from the public site, alongside product-page third-party testing and ≥99% purity callouts. That is vendor-hosted documentation rather than an outside-provider live verification flow.

Glacier Aminos

Curated

Included 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 public-structure case than it first appeared. Glacier’s storefront routes visitors through a research-access gate, but the live site still exposes a public catalog plus a dedicated public COA archive with lot/date-level PDF entries.

Testing transparency: Public COA archive API plus public catalog. Glacier’s strongest current public signal is the structured vendor-domain COA archive with lot- and date-level PDF entries, alongside a publicly browsable product catalog. That is materially stronger than generic purity claims, while still remaining vendor-hosted documentation rather than an outside-provider live verification system.

VAYN

Curated

Included 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 same products and formulas. Now at vayn.co with a clean public storefront and a growing public COA archive linked from product pages.

Testing transparency: Public COA archive with Chromate verification. VAYN at vayn.co exposes batch-level /coas/ pages linked from product pages, with Chromate verification on many certificates.

Silverstone Labs Co.

Curated

Included because Silverstone Labs Co has a public storefront with openly visible pricing, branded GLP labels (SLP-2, SLP-3), and repeatable product-gallery COA images.

A compact public catalog with branded GLP naming (SLP-2, SLP-3), core peptide coverage, and third-party testing callouts on product pages. COA images appear in galleries and on a public /certificates/ archive.

Testing transparency: Product-gallery COA images + certificates archive. Silverstone product pages repeatedly expose COA gallery images and third-party tested language, with additional vendor-hosted certificate assets on /certificates/. This is stronger than generic quality copy, but the files still live on the vendor domain rather than a provider-run verification portal.

Ignite Peptides

Curated

Included because Ignite Peptides has a public storefront with openly visible pricing, branded GLP labels (GLP-1 (S), GLP-2 (TZ), GLP-3 (RT)), and broad product-gallery COA coverage.

A broad peptide catalog with branded GLP naming, core research peptides, and third-party testing language on product pages. Many listings include a secondary gallery image with vendor-hosted COA or lab imagery.

Testing transparency: Product-gallery COA images. Ignite product pages repeatedly expose purity and third-party testing language, with COA or lab imagery in product galleries on most peptide listings. No dedicated public COA archive page was found at common paths.

Panda Peptides

Curated

Included because Panda Peptides (Xylo Research Systems LLC) has a public storefront with openly visible pricing, branded GLP labels (GLP-1S, GLP-2, GLP-3), and a public /coa/ archive with Janoshik verification links.

A research peptide catalog operated by Xylo Research Systems LLC with branded GLP naming, core peptides, and a public COA archive at /coa/. Product pages and the archive expose Janoshik verify links plus vendor-hosted COA images.

Testing transparency: Public Janoshik COA archive. Panda Peptides publishes batch-level COA cards on /coa/ with Janoshik public verification links, alongside COA gallery images and testing language on product pages.

Southern Aminos

Curated

Included because Southern Aminos has a public storefront with openly visible pricing, branded GLP labels (SA-2T, SA-3R, SA-4C), and embedded ILS Labs COA tables with portal verification links on product pages.

A research peptide catalog with branded GLP naming, broad vial coverage, and unusually deep per-product COA tables. Product pages publish batch-level purity, 8X testing panels, ILS Labs PDF reports, and portal verification links rather than generic quality copy alone.

Testing transparency: ILS Labs product-page COA tables. Southern Aminos embeds batch-level COA tables on product pages with ILS Labs verification links and downloadable COA PDFs. This is provider-verifiable public evidence, not just vendor-hosted images.

Pepvida

Curated

Included 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: Public COA PDFs. Pepvida publishes downloadable Certificate of Analysis PDFs on a public lab-results hub, alongside per-product COA pages. Sampled certificates carry real purity figures, but no third-party lab is named in the certificate text, so this is vendor-hosted documentation rather than provider-run verification.
