Every Certificate of Analysis we've ingested from optimasupply.is, what each tests for, and what's missing. Sourced back to the original COA URLs — no hosting, no editorial.
Each row is one peptide. Columns show whether at least one COA from this vendor for that peptide tests for that property. Endotoxin and sterility are usually the gap.

Most recent batches we've ingested. Each row links to the original COA file as published by the vendor.

How this is built: we discover every COA URL on the vendor's public testing page, fetch the file, run structured extraction, and persist what each COA actually tests for. Vendor copy isn't a signal — only the COAs themselves.
