Copper Tripeptide-1

Category: peptide

Aliases: GHK-Cu, Prezatide copper

Pharmacological Mechanism

Glycyl-histidyl-lysine + Cu²⁺ chelate — wound healing + anti-aging cosmetic peptide. Stimulates dermal fibroblast collagen + glycosaminoglycan synthesis; reduces TGF-β-driven scarring. Also as injectable in some research-chem markets for hair growth.
