About GHK-Cu

GHK-Cu is the copper(II) complex of the naturally occurring tripeptide glycyl-L-histidyl-L-lysine (Gly-His-Lys). First isolated from human plasma in the early 1970s, it has become one of the most extensively studied copper-binding peptides in dermatology, wound, and connective-tissue research. Puritide Research supplies GHK-Cu as a high-purity, research-use-only material for in vitro and animal-model investigation, backed by third-party-verified certificates of analysis so your data rests on consistent, documented quality.

What Is GHK-Cu?

GHK-Cu is a copper-bound tripeptide formed when glycyl-L-histidyl-L-lysine (GHK) chelates a copper(II) ion in a 1:1 stoichiometry. The GHK sequence occurs naturally in human plasma, saliva, and urine, where its concentration is reported to decline with age. Its high affinity for copper allows it to act as a carrier that shuttles the metal ion into cellular environments under study.

In experimental settings, GHK-Cu is used to investigate copper-dependent signaling in fibroblasts and keratinocytes, extracellular matrix remodeling, and gene-expression patterns associated with tissue repair. The bound copper is central to much of the observed biochemistry, distinguishing the complex from the free GHK peptide.

Present understanding derives from in vitro assays, animal models, and biochemical studies. Findings should be interpreted within their experimental context and not treated as established clinical outcomes. Puritide Research supplies GHK-Cu strictly for laboratory use; it is not approved for human or veterinary application.
