How can I verify a peptide vendor’s lab report myself?

Find the certificate for the exact lot you were shipped and check whether the laboratory named on it publishes its own lookup. 304 of the 585 certificates recorded here were signed by a laboratory that does. Each certificate page here links to that lookup and explains which identifier it wants, so the report can be pulled from the laboratory rather than from the vendor's own website.

What makes a certificate of analysis trustworthy?

Three things on the document itself: a named third-party laboratory that is not the vendor, an assayed mass printed against the labelled mass rather than purity alone, and a lot identifier that matches the vial you were sent. A certificate with no named laboratory, or one naming the vendor as its own tester, is not third-party evidence.

Does PepIndex test the peptides itself?

No. These 585 records are read from 560 documents that vendors and laboratories published. A vendor-published certificate is scored as a claim, not as corroboration; only an independently commissioned assay counts as verified.

Evidence

Every certificate behind the rankings

585 certificates of analysis, each on its own page with the laboratory that signed it, the lot it describes, the purity it reports and a link to the document itself. They cover 25 vendors and 36 compounds, and 304 of them name a laboratory that publishes a public lookup, so you can pull the report from the lab rather than from the vendor.

What is not here

A certificate only earns a page when the laboratory on it can be named and checked. Records whose laboratory field holds a placeholder, a signature block, or the vendor’s own name stay on that vendor’s profile and are counted against it, but they are not published here as evidence of third-party testing, because they are not evidence of it.

Every figure above is read from the document linked on its page. Where a field could not be read, it is recorded as absent rather than inferred.
