Testing: Labs & Certificates of Analysis

GenPeptide publishes a certificate library that lists each lot with its test date and report, current lots and earlier ones, with separate endotoxin and heavy-metal reports for many recent lots. When Prof. Peptide read it on 9 October 2026 it listed 147 entries.

94 of those entries correspond to reports issued to GenPeptide by Freedom Diagnostics, and the entries Prof. Peptide drew at random were checked at Freedom Diagnostics' own document store on 10 October 2026. Each carried the lot and product the library lists, and the lookup refused an invented code first, so a match means something. Freedom's reports cover identity by LC-MS, purity by HPLC and net content, and lots tested since September 2026 add endotoxin, microbial and heavy-metal screens.

All products are sold for laboratory research use only.
