Mechanism of action

GHK-Cu is the copper(II) complex of the tripeptide glycyl-L-histidyl-L-lysine, a sequence found in human plasma. Research attributes much of its activity to copper-ion delivery and to broad modulation of gene expression — transcriptomic studies report changes across thousands of genes, many related to extracellular-matrix (ECM) remodeling and collagen synthesis.

It is also studied for antioxidant and tissue-remodeling signaling in fibroblast and skin-model systems, strictly within research contexts.
