PeptideCensus is the independent index of public peptide lab results. We aggregate published third-party test results (COAs), track batch purity against label claims, and rank vendors by verified data — free, updated daily, with every number linked to its original source.
A large share of research peptides tested by independent labs miss their label claims. The data proving it is scattered across lab verification pages, vendor sites, and forum threads. We put it in one place and keep it current, so the published record — not marketing — decides who is trustworthy.
We are not a lab, a tester, or a certifier. PeptideCensus does not conduct testing and never claims to. We collect what independent laboratories have already published, credit the source, and link to it. “Verified” on this site means a published third-party result exists — never that we verified it ourselves.
Affiliate links and coupon codes on vendor pages, clearly labeled sponsored placements, and referral partnerships with testing laboratories. Commissions never influence scores or rankings; the full policy is on our How We Score page.
Nothing on this site is medical advice; compounds shown are sold for research purposes only.
