GHK-Cu · Copper-peptide research context
An educational overview of what researchers have and have not established about GHK-Cu. Education only · provider review required.
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.
Research status

Status reflects published research context only and is not a statement of safety, efficacy, or suitability for any person.
Is it legal?
Regulatory status varies by country and can change, and GHK-Cu appears in different regulatory categories depending on context and formulation. Its status and permitted uses should be confirmed against current official sources rather than assumed. Nothing on this page is a claim about approval, safety, or suitability for any purpose.

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.
