Peptides by compound: who holds a verifiable certificate for each

By Jamie, Editor · The Peptide Watch · updated 13 October 2026

39 compounds, 41 verified sellers, 427 Janoshik reports opened and read. For each compound this table shows how many verified UK sellers hold an own-name certificate covering it that we have opened on the laboratory's own site, and whose certificate is newest. Click the compound for the full list, the reports themselves, and what the research says. Audit findings, not recommendations: The Peptide Watch sells nothing and links to no seller.

A seller appears against a compound only when we have opened a Janoshik report that names the seller as the client and covers that compound; the count and the date come from those reports and nothing else. A vendor whose report we have not yet read is not counted. The dates are the analysis date printed on the report. Also see the verified sellers ranked by newest certificate, how to verify a certificate yourself, and what the blend names mean.
