Description
GHK-Cu, also known as Copper Tripeptide-1, is a naturally occurring copper-binding tripeptide composed of Glycine Histidine Lysine (GHK) complexed with Cu²⁺. First identified in human plasma, GHK-Cu plays a key biological role in skin regeneration, tissue repair, and cellular remodeling.
This peptide is widely researched for its ability to support collagen synthesis, anti-inflammatory activity, and wound-healing pathways. When bound to copper, GHK exhibits enhanced biological stability and signaling potential, making GHK-Cu the bioactive form commonly used in scientific applications.
In its pure form, GHK-Cu appears as a fine blue powder due to the copper complexation. It is highly soluble in water and suitable for diverse research environments.
