Testing: Labs & Certificates of Analysis
Modern Research Peptides' certificate library holds about 140 Freedom Diagnostics reports, one per lot, each with Freedom's accession number; the certificates name the compound's identity by LC-MS, its HPLC-UV purity and the net content.
Prof. Peptide looked up three of these certificates at Freedom Diagnostics' own records, each issued to MRP, the client name the laboratory prints on Modern Research Peptides' certificates: Cagrilintide 5 mg (MRP2608120207), GLP1-S 30 mg (MRP2606150339) and BPC-157 20 mg (MRP2607070253). Those three certificates' results are below.
