GHK-Cu is a naturally occurring copper peptide famous in skin and repair research for stimulating collagen, firming and renewing skin, and supporting wound healing.
Copper-binding tripeptide
The pathways GHK-Cu acts on — and what each one does. The animation traces its signal outward from the compound to every target it engages.
GHK-Cu chelates copper(II) ions and delivers them to cells, activating copper-dependent enzymes essential for collagen crosslinking, antioxidant defense, and tissue remodeling.
Stimulates fibroblasts to produce type I and III collagen, glycosaminoglycans, and decorin — rebuilding the extracellular matrix architecture in damaged tissue.
Gene expression studies show GHK-Cu modulates 4,000+ human genes, resetting expression patterns toward a healthier, more youthful state. This is among the broadest gene-modulatory effects of any known peptide.

GHK-Cu (glycyl-L-histidyl-L-lysine copper) is a naturally occurring copper-binding tripeptide first isolated from human plasma in 1973 by Dr. Loren Pickart. It is found in human blood, saliva, and urine, with plasma levels declining from approximately 200 ng/mL at age 20 to 80 ng/mL by age 60.
Preclinical research has demonstrated that GHK-Cu may promote wound healing and skin repair by stimulating collagen and glycosaminoglycan synthesis; attract immune and endothelial cells to injury sites; have anti-inflammatory and antioxidant properties; and modulate the expression of over 4,000 genes toward healthier patterns.
GHK-Cu is not FDA approved as a drug. It is available as a research peptide and is also found in some cosmetic formulations. Injectable forms are sold exclusively for in vitro research purposes.
In research settings, GHK-Cu is typically reconstituted in bacteriostatic water and administered subcutaneously in animal models. Common research dosages range from 1-10 mg/kg in preclinical studies.
GHK-Cu consists of three amino acids — glycine, histidine, and lysine — complexed with a copper(II) ion. The molecular formula is C₁₄H₂₄CuN₆O₄ with a molecular weight of approximately 403.9 Da. The histidine residue provides the primary copper-binding site.
Lyophilized GHK-Cu should be stored at -20°C for maximum stability (up to 24 months). After reconstitution, refrigerate at 2-8°C and use within 30 days. Avoid repeated freeze-thaw cycles and protect from light.
