GHK-Cu (Copper Tripeptide-1)

GHK-Cu is a copper peptide: the tripeptide glycyl-histidyl-lysine (GHK) bound to copper. On cosmetic labels it goes by its INCI name, Copper Tripeptide-1. We supply it in two grades and keep them strictly apart: cosmetic grade for skincare brands and formulators making topical products, and research grade in vials for laboratories we have verified.
