GHK-Cu research material
GHK-Cu is the copper(II) complex of glycyl-L-histidyl-L-lysine, a tripeptide first isolated from plasma in the 1970s and noted for its very high affinity for copper ions. Copper is held by the glycine amine, the adjacent backbone nitrogen and the histidine imidazole, with lysine's long side chain left free. GHK-Cu is one of the most widely studied copper peptides in cell-culture and skin-biology research, and it is also listed in cosmetic ingredient databases as copper tripeptide-1.
GHK-Cu Labs supplies it as a blue lyophilized powder in 50 mg and 100 mg vials. Each lot is tested by an independent laboratory for HPLC-UV purity, LC-MS identity and net content, and the full certificate is published here before sale through Klow.bio.
