Vendor trust rankings

We grade every vendor on evidence you can verify: independent third-party lab results and batch-specific certificates of analysis. Vendors can't buy a better grade — rankings come from data, not deals.

Each vendor gets a PeptidePub Testing Score — a 7-point checklist scored from their published certificates of analysis: net content, purity, identification, heavy metals, sterility, endotoxins, and contaminant screening. More checks verified = higher score.
