What it is

A copper peptide, studied in the lab.

GHK-Cu is a naturally occurring copper-binding tripeptide (glycyl-L-histidyl-L-lysine). It is investigated in preclinical, in-vitro models of extracellular-matrix and collagen-related signaling, gene-expression modulation, and antioxidant-enzyme regulation. Supplied as a lyophilized powder for laboratory research — not for human or veterinary use, and not a drug or dietary supplement.
