Research classification: Cellular, preclinical, and limited clinical literature
Compound overview
GHK-Cu refers to a copper complex of the tripeptide glycyl-L-histidyl-L-lysine. Copper coordination, solution conditions, and chemical form can influence experimental interpretation.
Published research
Published reviews discuss GHK-related cellular signaling, extracellular matrix biology, and skin-oriented research. The literature includes laboratory and preclinical models; clinical evidence is less extensive and often uses specific topical formulations.
Evidence limitations
Research on GHK alone or topical preparations should not be treated as evidence for any independently supplied GHK-Cu vial or another route of exposure.
