HPLC identity-purity analysis
High-Performance Liquid Chromatography separates and quantifies peptide components to confirm ≥99% identity purity.
IDENTITY VERIFIED
Certificate of Analysis
Every peptide we sell is third-party identity-tested and ships with full documentation of purity and identity verification.
A Certificate of Analysis (CoA) is your proof that what is on the label is what is in the vial. We believe in complete transparency — every batch, every time.
