Proforma Peptides is the cleanest of the non-Janoshik sites: it commissions genuine Certificates of Analysis from Analiza Białek, a real independent lab, with itself as the client. The only mark against it is that it's Analiza, not the Janoshik standard this index is built on, so it sits just outside the independently-tested list rather than among the bad actors. Aggravating: the reports seen are dated September 2025 and served from personal Dropbox links.
