GHK-Cu

A copper binding tripeptide commonly researched in skin and hair biology.

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.
