• Mass spectrometry (MS) to verify peptide sequence and molecular weight
• COA, MSDS and HPLC chromatograms supplied with each shipment as standard
• Full traceability from raw material intake through nitrogen-sealed final packaging
• Retain samples archived per batch to support future reference and quality follow-up
