GHK-Cu: The Copper Peptide at the Center of Skin and Tissue-Repair Research
What GHK-Cu is, why it draws research interest, and what research-grade material means.
GHK-Cu is a naturally occurring copper-binding tripeptide that has become one of the most-studied compounds in skin and connective-tissue research. First isolated from human plasma, its levels decline with age — part of why it draws so much interest.
What GHK-Cu is
GHK-Cu is the peptide glycyl-L-histidyl-L-lysine bound to a copper ion. In research it is studied as a signaling molecule that appears to influence genes involved in tissue remodeling and repair.
Why researchers study it
Published work examines GHK-Cu in models of collagen and elastin production, wound-healing pathways, and antioxidant activity in skin tissue — a recurring “signaling for repair” theme.
What the evidence shows
Much of the strongest data comes from in-vitro and animal models; human research is growing but still developing. The value is in well-characterized, reproducible material.
