How our testing works
Samples from each production lot are sent to an independent, ISO-accredited analytical laboratory. Certificates report peptide identity (mass spectrometry), purity (reverse-phase HPLC), water content, and endotoxin levels where applicable. Lot numbers on the vial map directly to the corresponding COA.
