Testing: Labs & Certificates of Analysis

American Peptides publishes a certificate library organized by product, size and lot, where Prof. Peptide counted 65 current and 28 superseded lot certificates on 9 October 2026. American Peptides states that every batch is independently tested for identity and purity, at 99% or higher by HPLC and mass spectrometry.

Every certificate is issued by Bioviridian Inc., and the certificates Prof. Peptide drew from the library were checked at Bioviridian's own file store on 9 October 2026. Each named American Peptides as the vendor and matched the vendor's copy on every shared field, and the store refused three invented codes first, so a match means something. Bioviridian's current issues report identity by LC-MS/MS, content, purity by RP-HPLC, endotoxin, heavy metals and sterility.

All products are sold for laboratory research use only.
