What is GHK-Cu?

Copper-binding peptide research and cellular biology

GHK-Cu is a naturally occurring copper-binding peptide complex consisting of the tripeptide glycyl-L-histidyl-L-lysine (GHK) associated with copper ions.

GHK has been studied in biological research because of its ability to interact with copper and its proposed involvement in cellular signaling, extracellular matrix processes, and tissue biology.

Research surrounding GHK-Cu has examined a range of biological processes including collagen-related activity, cellular communication, tissue remodeling, and responses associated with oxidative and inflammatory signaling.

Why is GHK-Cu unique?

Understanding the biological role of the GHK-Cu peptide complex

GHK-Cu is a naturally occurring copper-peptide complex formed by the binding of copper to the tripeptide glycyl-L-histidyl-L-lysine (GHK). Its unique research profile comes from the combination of peptide signaling and copper-dependent biological activity. Research has investigated GHK-Cu in relation to extracellular matrix regulation, collagen-associated processes, cellular signaling, inflammation, and tissue remodeling, particularly within the field of skin and connective-tissue biology. These mechanisms continue to be investigated across laboratory, preclinical, and selected clinical research models.
