GHK-Cu is formed when the tripeptide GHK (glycine, L-histidine, L-lysine) binds copper(II). It is one of the best-known copper peptides, appears on cosmetic ingredient lists as Copper Tripeptide-1, and is widely used in laboratory research.
We manufacture GHK-Cu as a lyophilized powder and supply it through two separate lanes: research-grade vials for laboratories and distributors, and bulk ingredient supply for skincare brands and formulators. The two lanes use different documentation and different customer verification.
