Product Overview

GHK-Cu, also known as Copper Tripeptide-1, is a naturally occurring copper-binding tripeptide consisting of glycine, histidine, and lysine coordinated with copper (Cu²⁺).

GHK-Cu has been extensively investigated in laboratory and preclinical research involving extracellular-matrix biology, cellular signaling, connective-tissue remodeling, and skin biology.

The copper-binding characteristics of GHK-Cu make it an important research model for studying interactions between bioactive peptides and metal ions. Research has also examined its relationship with collagen-associated processes, fibroblast activity, cellular signaling, and tissue remodeling.
