Understanding Peptide Purity

Peptide purity is typically expressed as a percentage. For research purposes, most users look for peptides with 98% or higher purity. The purity level indicates what percentage of the product is the actual peptide versus impurities or synthesis byproducts.

HPLC (High-Performance Liquid Chromatography) is the standard method for testing peptide purity. A proper COA should include HPLC results along with mass spectrometry data to confirm the identity of the peptide.
