Product Overview

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

The GHK tripeptide has been investigated extensively in laboratory research involving extracellular-matrix biology, cellular signaling, tissue remodeling, and skin biology. Its ability to coordinate copper makes GHK-Cu an important model for studying interactions between bioactive peptides and metal ions.

GHK-Cu is also widely studied in cosmetic and biological research involving collagen-related processes, fibroblast activity, wound-repair mechanisms, and extracellular-matrix regulation.
