Under its full chemical designation, Copper(II) glycyl-L-histidyl-L-lysine complex, GHK-Cu is a naturally occurring copper-binding tripeptide presented in a sterile glass vial as a lyophilized powder. Published laboratory research across peptide science has named it in connection with dermal biology, gene expression, connective tissue biology, cellular communication, inflammatory signalling and extracellular matrix biology.
The scientific literature records further work on the complex in molecular biology, tissue biology and cell biology.
