EXPLORE GHK-CU
GHK-Cu is the copper complex of the tripeptide glycyl-L-histidyl-L-lysine. GHK occurs naturally in human plasma and can bind copper(II). In research, the complex is examined as both a copper carrier and a signaling molecule in fibroblast, extracellular-matrix, skin, and wound models.
Cell and animal studies report changes in collagen synthesis, glycosaminoglycans, decorin, matrix metalloproteinases, and other remodeling-associated signals. Copper binding is central to its chemistry, but the biological response depends on concentration, cell type, available copper, and formulation. It is not reducible to “more collagen.”
Researchers use GHK-Cu to examine how small copper-binding peptides influence matrix production and turnover, fibroblast activity, oxidative balance, and tissue organization. Common endpoints include collagen, proteoglycans, metalloproteinases, gene expression, histology, and material-scaffold performance.
GHK-Cu couples peptide signaling with metal-ion coordination. That gives it chemistry that plain GHK and free copper do not necessarily share. Concentration-response curves can be non-linear, and the same complex may affect both matrix production and matrix remodeling.
EVIDENCE BOUNDARY
Most mechanistic evidence is in cells, engineered materials, or animals. Topical and injectable routes are not interchangeable. FDA has identified limited human data and potential immunogenicity concerns for compounded injectable GHK-Cu related to aggregation and peptide impurities.
