GHK-Cu is a naturally occurring copper-binding tripeptide complex consisting of the peptide glycyl-L-histidyl-L-lysine chelated to a copper (II) ion, found endogenously in human plasma, saliva, and urine. Supplied as a lyophilized powder in a sealed laboratory-grade glass vial. Intended for in-vitro and laboratory research applications only. Research ContextGHK-Cu is studied in in-vitro and animal-model research across several converging molecular pathways. It is investigated as a modulator of gene expression, with reported associations to over 4,000 human genes in research models. Reported research subjects include collagen, elastin, and glycosaminoglycan synthesis pathways, VEGF-associated angiogenesis signalling, and antioxidant and inflammation-related pathways involving superoxide dismutase. Its copper-chelating properties are examined in relation to extracellular matrix remodelling pathways, and its documented interactions with TGF-β signalling and stem-cell-associated markers make it a subject of interest in skin biology, extracellular matrix research, hair follicle research, and related molecular investigation.
