What it is
GHK-Cu is a tripeptide (Gly-His-Lys) that binds copper(II) and forms a stable complex. It is widely used as a research and cosmetic ingredient.
How it works
In research models, GHK-Cu is studied in pathways related to copper homeostasis, gene expression in skin cell research, and extracellular-matrix turnover.
What researchers explore it for
Researchers have explored GHK-Cu in skin biology research, in hair follicle research, and in copper-pathway research.
Safety and interactions
GHK-Cu is for laboratory research use only and is not for human consumption. Not medical advice.
Research notes
Peptide family: copper binding peptides. The injectable research format is on the PCAC review docket — Apothify is not shipping GHK-Cu at V1 launch.
