GHK-Cu

GHK-Cu (Glycyl-L-Histidyl-L-Lysine-Copper) is a naturally occurring copper-binding peptide found in human plasma, saliva, and tissues. Composed of a tripeptide bound to a copper ion, GHK-Cu has been widely studied for its involvement in tissue repair, cellular signaling, and protective biological responses. Research indicates that GHK-Cu plays a role in wound-healing pathways, modulating inflammation, and supporting structural components of the skin. Scientific interest in GHK-Cu has grown due to its potential influence on gene expression related to regeneration, antioxidant activity, and extracellular matrix organization. These properties have made it a prominent subject in dermatologic, cosmetic, and regenerative research. Investigational studies have…
