VENDOR AUDIT

CertaPeptides

EU-based (Romania) research-peptide supplier that does the thing our rubric rewards — real third-party Janoshik COAs hosted on Janoshik's own public portal, with verifiable report IDs, real compound names, and an honest two-tier split between "independently tested" lots and "supplier batch specification" lots. The main caveats are scope and age — only about a third of the catalog has an independent report (the rest is a supplier ≥98% class spec, not a per-lot measurement), and the operation is new despite a "founded 2024" claim. Public-data preview; first-hand audit pending.
