Its relatively small molecular weight (163.29 g/moL) supports efficient cellular uptake and redox regulation

A redox perspective

GHK-Cu stands apart from signal peptides (like argireline/acetyl hexapeptide-3) that work by modulating neurotransmitter release at the neuromuscular junction

The PKC pathway becomes activated through hyperglycemia-induced increases in diacylglycerol (DAG), with PKC- and PKC- isoforms particularly implicated in stimulating NOX activity while inhibiting AMPK-mediated antioxidant responses (Geraldes and King, 2018)

Some formulations combine copper peptides with vitamin C derivatives that are less prone to oxidation
