Testing: Labs & Certificates of Analysis
IRON's certificates are issued by Freedom Diagnostics. Each reports identity, purity, net peptide content and appearance, analysed by HPLC with UV detection coupled to mass spectrometry, and prints a search code that opens the laboratory's own copy at Freedom Diagnostics' document store. IRON Peptides states that every lot is independently assayed.
Prof. Peptide read three of its certificates at Freedom Diagnostics' own document store on October 11 and 22, 2026: GHK-Cu 50mg (99.791%), KLOW 80mg (99.5%) and BPC-157 10mg (99.18%), each naming IRON Peptides as the client. The panel below lists every certificate's own results.
