This is an index. Each row is a compound we track, how many of its vendors publish lab results we can link to, and how many of those are per-batch certificates (a specific lab report, COA PDF, or certificate image). The purity shown is the highest we read off any of those certificates; we never post a number that isn’t printed on a document we link. Because a COA belongs to one vendor and one batch, the actual certificates live on each product page: open one to see every vendor’s COA side by side. We don’t run the labs; we link you straight to the source.
What purity and the mass-spec peaks actually tell you, and how to spot a faked certificate before you buy.
One row per compound, showing the strongest source we found and the highest purity any carrying vendor reports. Click “all →” to see every vendor’s COA for that peptide. Purity figures are vendor-reported and link to the original document; we don’t test anything ourselves. Last checked June 9, 2026.
