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 99 of 211 certificate records can be confirmed at the issuing lab.
Readers who want a wide catalog where many batches are backed by a third-party lab report they can verify at the lab’s own site.
The reports are RP-HPLC purity + identity, so they are strong on purity but do not run the endotoxin/heavy-metals/sterility safety panels. A handful of certificate scans are too low-resolution for us to read the verification code, so prefer the batches that carry a verify link.
Freedom Diagnostics + Chromate COAs with public provider verification
GenPeptide’s public /coa-lookup/ gallery lists batch-level reports across the catalog, and many 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. 99 of 211 certificate records carry a live provider-verification link — provider-verifiable public evidence rather than generic third-party language.

Assayed content is not fill accuracy. Laboratories report net peptide content, and peptides ship as salts, so an honestly filled vial commonly assays below its gross label — a figure under 100% is not evidence of a short vial. These numbers are also not comparable between vendors: they exist only where a laboratory reports net content, so they partly reflect which laboratory a vendor uses.
