Medically reviewed by Bernard Garcia, MD

What it is

GHK-Cu is a naturally occurring copper-binding tripeptide composed of the amino acids glycine, histidine, and lysine complexed with a copper ion. The scientific literature describes it as a molecule present in human plasma whose measured levels have been reported to change with age.

Research interest in GHK-Cu centers on its role as a copper-carrier peptide and on its behavior in laboratory and skin-science studies. This page summarizes how GHK-Cu is framed in that research literature and does not describe any therapeutic use or outcome.

How it works

Mechanistically, GHK-Cu is discussed in the literature in relation to its high affinity for copper ions and the transport of copper in biological systems. Researchers have examined how the peptide-copper complex interacts with cells in culture and how it is associated with the expression of various genes in experimental models.

Much of the published work discusses GHK-Cu in the context of extracellular matrix proteins and tissue-remodeling pathways studied in vitro. Whether these laboratory observations carry any clinical significance has not been established here and is a matter for qualified researchers and licensed providers to evaluate.

Frequently asked questions

What is GHK-Cu?

It is a naturally occurring copper-binding tripeptide (glycine-histidine-lysine plus copper) studied in biochemistry and skin-science research. This page is educational and not a recommendation for use.

Why is copper part of the name?

The peptide binds a copper ion with high affinity, and the literature discusses it as a copper-carrier molecule. The significance of this is a matter for qualified researchers and licensed providers.

Is GHK-Cu appropriate for me?

This page cannot answer that. A licensed provider determines appropriateness only after a confidential intake and review of your individual circumstances.

Where do the research claims come from?

The research summary on this page links to a primary source record for this compound, such as its public NIH database entry, where applicable. This page is educational only and is not a substitute for advice from a licensed provider.
