GHK-Cu, the copper complex of the tripeptide glycyl-L-histidyl-L-lysine, occurs naturally in human plasma and is one of the best-characterised peptides in dermatological research. It has been studied for collagen and extracellular-matrix synthesis, wound-healing models and gene-expression effects in vitro, and it is widely used in topical cosmetic formulations.

We supply GHK-Cu as a research-grade lyophilised powder and as part of the KLOW blend. Its blue colour comes from the copper complex.
