GHK-Cu 50mg

GHK-Cu is the tripeptide glycyl-L-histidyl-L-lysine complexed with copper(II). The GHK sequence occurs naturally in human plasma, where its concentration declines with age, and it binds copper with high affinity — the property that makes it a subject of extracellular-matrix and collagen-remodelling research. It appears widely in dermatological and wound-model studies. Supplied lyophilised as the copper complex, which gives it a characteristic blue colour. Independently assayed by a third-party laboratory, named on this page; the certificate of analysis for this lot, with its measured purity and batch number, is published on this page. For laboratory research use only.
