Testing: Labs & Certificates of Analysis
Peptide Partners publishes a certificate index searchable by compound, batch, laboratory and date, where Prof. Peptide counted 424 records on 8 October 2026: 133 purity, 122 endotoxin, 110 heavy-metal and 59 sterility reports. The Manufacturer ID and Batch ID on each product page lead to the certificates for that stock.
Certificates from three of the index's laboratories were checked at each laboratory's own lookup on 8 October 2026: Kovera Labs, Chromate and BioRegen. Each named Peptide Partners as the client and matched the vendor's copy, and each lookup refused an invented code first, so a match means something. Kovera's peptide reports cover purity, net content, identity by LC-MS, endotoxin, 14-day sterility and a heavy-metal screen; Chromate's report purity and quantity across the vials of a batch, and on some an endotoxin count and a metals screen; and BioRegen's cover earlier batches, from July 2025 to January 2026.
Finnrick rates Peptide Partners 66% across 103 tests (read 8 October 2026) — a pass rate across those tests, weighted so that newer tests count for more, not a purity figure.
All products are sold for laboratory research use only.
