99% Purity GuaranteedHigh-Performance Liquid Chromatography (HPLC) separates and quantifies the peptide in the sample and confirms its identity. Every batch must pass at ≥99% purity before any vial ships. Three vials per batch are tested, and quantitation and identity are confirmed across the three vials to confirm batch conformity. Results appear on the batch-specific COA at ILS Laboratories, an ISO/IEC 17025-accredited US testing facility.
Confirmed by HPLC on every batch.
