HPLC — Purity
Reverse-phase HPLC at 214/220 nm quantifies chromatographic purity and detects related impurities. Release spec ≥99% area.
Mass spectrometry — Identity
ESI-MS confirms the peptide’s molecular weight against its theoretical mass to verify sequence identity.
Independent labs
Testing is contracted to ISO/IEC 17025-accredited laboratories. No result is reported by the manufacturer alone.
Each vial, carton and COA share one batch ID. Enter it above, or find the full testing methodology and release specification in our FAQ.
