GHK-Cu

GHK-Cu is a naturally occurring copper-binding tripeptide composed of glycine, histidine and lysine complexed with a copper(II) ion. It is found in human plasma, saliva and urine, and is one of the most extensively studied copper peptides.

Laboratory studies report that GHK-Cu stimulates collagen, elastin and glycosaminoglycan production and modulates a large number of genes involved in tissue remodeling. It has been studied for fibroblast proliferation, keratinocyte migration and wound-healing models, with some studies reporting collagen increases of up to ~70%.

The copper ion is integral to the peptide’s biological activity and gives reconstituted solutions their characteristic blue tint. Because copper is biologically active, researchers handle GHK-Cu with attention to concentration and potential copper-related effects in their models.

Keep the lyophilized powder cold (-20°C for long-term storage), away from light. Reconstitute with bacteriostatic water added gently down the vial wall and swirl — do not shake. Refrigerate the reconstituted solution at 2–8°C; a faint blue color is normal due to the copper complex.
