Bench Grade Peptides Review: Pricing, COAs, Testing, and What We Found
An independent Bench Grade Peptides review covering Dover DE registration, public /coa/library certificates from Chromate, Freedom Diagnostics, and Bioviridian, house GLP codes, and openly listed vial prices.
Bench Grade Peptides is now a curated vendor on PeptideBenchmark. That decision rests on evidence a reader can open and check — catalogue prices, vial strengths, and a public per-lot certificate library — not on a testimonial or a vague “third-party tested” claim.
Two things stood out. First, the storefront keeps prices and size variants on the public catalogue without an account wall. Second, the /coa/library publishes per-lot pages whose Chromate and Bioviridian documents resolve at each laboratory’s public verification surface when the printed codes check out. Freedom Diagnostics PDFs on the same library that print client Wholesale stay source-linked only.
Reviewed August 31, 2026. PeptideBenchmark has no affiliate, coupon, sponsorship, or paid-placement relationship with Bench Grade Peptides. The vendor sells research-use-only products; this is a commercial-transparency and documentary-evidence review, not human-use guidance or medical advice.
The short version
We found a public research storefront with:
- openly listed single-vial prices and size variants on the catalogue;
- a Delaware LLC mailing address (8 The Green, Dover, DE 19901) on the Contact page;
- a public /coa/library of per-lot certificate pages with downloadable documents;
- house labels GLP-1 S (semaglutide), GLP-2 T (tirzepatide), GLP-3 R (retatrutide), and AMY-A (cagrilintide).
PeptideBenchmark independently confirmed 52 of 72 scored certificate lots at Chromate or Bioviridian. The remaining 20 Freedom Diagnostics PDFs print client Wholesale and stay vendor-hosted source evidence. A certificate still describes the named sample, not every unit or a blanket safety conclusion.
The catalogue is readable without an account, lot pages print purity / lab / COA identifiers, and Chromate plus Bioviridian codes resolve at the labs for most of the published set. Against that: the domain is newly registered (April 2026), Freedom prints that name client Wholesale are not Bench Grade–named provider reports, and bacteriostatic water stays off the peptide $/mg board.
What we found in the catalog
Bench Grade Peptides publishes its priced research catalogue publicly. Most peptides are single-vial offers with milligram strengths in the size selector. PeptideBenchmark promotes every clean mg-normalized vial row so $/mg comparisons stay honest.
| Catalog result | Count | PB treatment |
|---|---|---|
| Public parent products | 34 | Retained in the coverage audit |
| Comparable vial rows after size expansion | 66 | Published to Pricing and Stack Builder |
| Deferred | 0 | — |
| Out of scope | 2 | Bacteriostatic water size variants |
House labels matter here:
- GLP-1 S → semaglutide
- GLP-2 T → tirzepatide
- GLP-3 R → retatrutide
- AMY-A → cagrilintide
- GLOW / KLOW / BPC/TB / CJC/IPA → blend aliases retained as vendor-aligned rows
Current offers can be compared on PeptideBenchmark Pricing, and mixed-product requirements can be modeled in the Stack Builder.
Testing and certificates
The public /coa/library lists per-lot pages for the catalog. Each page names the compound, lot, HPLC purity, laboratory, and COA number, and links a certificate image or PDF. Across the scored set we reviewed:
- Chromate lots with Job + Access pairs that resolve at chromate.org
- Bioviridian PDFs whose
COA######codes resolve at bioviridians.com - Freedom Diagnostics PDFs hosted on the vendor library that print client Wholesale — retained as source-linked OEM evidence, not counted as Bench Grade–named provider verification
Reported HPLC purity averaged about 99.4% across lots with a numeric purity field. Panel depth varies by lab and report — identity and HPLC are common; endotoxin / sterility / heavy-metals coverage is not uniform across every lot.
Live evidence widgets stay on the Bench Grade Peptides vendor profile. Filtered COA records appear in the COA database when archive ingestion is complete.
What the evidence does not support
A matched Chromate or Bioviridian certificate documents the tested sample named on that report. It does not:
- prove every shipped vial matches that lot;
- convert a Wholesale-client Freedom PDF into a Bench Grade–named provider report;
- establish sterility, endotoxin, or heavy-metals coverage when those panels are absent;
- endorse human use (the storefront is research-use-only);
- make PeptideBenchmark an affiliate or sponsored placement for this vendor.
Location and commercial terms
Vendor-stated as of this review: Bench Grade Peptides LLC, 8 The Green, Dover, DE 19901; admin@benchgradepeptides.com; (954) 418-2621; unconditional free shipping nationwide highlighted on the storefront. Domain registration is recent (April 2026). Those are dated observations, not evergreen promises.
Bottom line
Bench Grade Peptides clears PeptideBenchmark’s curated bar on commercial transparency: public prices, mapped house GLP codes, and a public multi-lab COA library with provider verification at Chromate and Bioviridian for most scored lots. Read the live vendor profile, compare pricing, and check how scoring works before treating any certificate as more than a documentary record of the named sample.
Common questions
Is Bench Grade Peptides legitimate?
PeptideBenchmark does not issue binary legitimacy or product-safety endorsements. We confirmed an openly priced research catalog, a Delaware LLC mailing address on the Contact page, and a public /coa/library whose Chromate and Bioviridian certificates resolve at each laboratory’s public verification surface when the printed codes check out. Freedom Diagnostics PDFs that print client Wholesale stay source-linked only. Those facts create an inspectable record; they do not establish the condition or safety of a physical vial.
Does Bench Grade Peptides publish COAs?
Yes. The public /coa/library lists per-lot certificate pages with downloadable documents. PeptideBenchmark confirmed Chromate Job/Access pairs at chromate.org and Bioviridian COA###### codes at bioviridians.com for the provider-verified subset reviewed here. Freedom Diagnostics prints that name client Wholesale remain vendor-hosted source evidence.
What do GLP-1 S, GLP-2 T, GLP-3 R, and AMY-A mean?
They are Bench Grade Peptides storefront labels. Product pages and matching certificates identify GLP-1 S as semaglutide, GLP-2 T as tirzepatide, GLP-3 R as retatrutide, and AMY-A as cagrilintide.
Where is Bench Grade Peptides based?
The public Contact page and Organization schema list Bench Grade Peptides LLC at 8 The Green, Dover, DE 19901, with admin@benchgradepeptides.com and phone (954) 418-2621.
Does PeptideBenchmark have an affiliate relationship with Bench Grade Peptides?
No. At the time of this review, PeptideBenchmark had no affiliate, coupon, sponsorship, or paid-placement relationship with Bench Grade Peptides. The vendor does advertise a public affiliate program on its own site.
