Description & Mechanism GHK-Cu is a naturally occurring copperpeptide complex that functions as an endogenous signalling molecule involved in metal ion transport and cellular regulation
GHK-Cu works through copper delivery to metalloenzymes and broad gene expression modulation, affecting not only collagen synthesis but also collagen cross-linking (via lysyl oxidase), glycosaminoglycan production, anti-inflammatory pathways, and antioxidant defense systems
