GHK-Cu: A Copper Peptide Research Overview

GHK-Cu is a naturally occurring copper-binding tripeptide that has been studied extensively in skin-biology and tissue-remodelling research. Its concentration in human plasma is reported to decline with age, which has shaped much of the research interest around it.

What is GHK-Cu?

GHK-Cu consists of the tripeptide glycyl-L-histidyl-L-lysine bound to a copper ion. In laboratory research it is studied as a model compound for copper-dependent signalling and its influence on extracellular-matrix components.

Pathways studied in the literature

• Collagen and elastin synthesis in dermal-tissue models.
• Wound-healing and tissue-remodelling pathways.
• Antioxidant and anti-inflammatory signalling.
• Gene-expression changes associated with tissue repair.

Summary of research findings

GHK-Cu is among the more thoroughly characterised peptides in skin-research literature, with numerous in vitro and animal studies examining its effects on matrix biology. Interpretation should remain anchored to the laboratory contexts in which these effects have been observed.
