GHK-Cu is a naturally occurring complex of the tripeptide glycyl-histidyl-lysine and a copper ion. It was identified in human plasma by Dr. Loren Pickart in the 1970s, and plasma levels are reported to fall substantially between early adulthood and the sixties. It is one of the most studied molecules in collagen, extracellular-matrix and skin research.
Quick authenticity check: genuine GHK-Cu is blue to violet because of the copper. A white powder sold as GHK-Cu is a red flag (colour alone does not prove identity, which is why we test by mass spectrometry).
Maquart et al. (1988, FEBS Lett) reported stimulated collagen synthesis in human fibroblast cultures at nanomolar concentrations; later work extended this to elastin, glycosaminoglycans and matrix-remodelling enzymes.
Using the Broad Institute Connectivity Map, Pickart et al. (2015, 2018) reported that GHK shifts expression of many genes linked to tissue repair, antioxidant defence and inflammation.
Animal wound models report faster contraction and better-organized tissue; copper peptides are also examined in dermal papilla and follicle cultures.
Honest caveat: the findings above come from published laboratory and preclinical research, or from clinical studies of the compound class. They describe what has been studied, not what this product will do.
