Third-party testedCopper Peptide Complex
GHK-CU
GHK-Copper (GHK-Cu) is a copper complex of the tripeptide glycyl-L-histidyl-L-lysine. In-vitro research explores its role in collagen synthesis, antioxidant activity, and the regulation of gene expression.
About the compound
What GHK-CU is.
GHK-Cu is three amino acids bound to a copper atom. It occurs naturally in human plasma and measured levels fall with age. Laboratory research has investigated it for effects on collagen production and skin cell behaviour in tissue models.

Research
What GHK-CU has been studied for.
A plain-language summary of the published work. Almost all of it is in cells and animals — where a study was done in people, it says so.
01
Collagen production
GHK-Cu is three amino acids bound to a copper atom. Skin-cell studies have measured whether it increases the production of collagen and other structural proteins in tissue models.
02
Falls with age
It occurs naturally in human plasma, and measured levels decline substantially from young adulthood onwards — an observation that prompted much of the later research.
03
Wound healing models
Animal studies have looked at its effect on the speed and quality of wound closure.
04
Gene expression in skin cells
Laboratory work has profiled which genes change activity in skin cells exposed to GHK-Cu, including genes involved in tissue remodelling.
