GHK-Cu

A naturally occurring copper-binding tripeptide complex formed from glycine, histidine and lysine, widely studied in skin, wound and extracellular-matrix research.

In laboratory research, GHK-Cu is primarily examined in relation to copper signalling, extracellular-matrix biology, wound models and skin-cell research. The strength and type of evidence vary by compound and may be limited to mechanistic, cell-culture or animal studies.
