demonstrates that GHK-Cu promotes ECM component synthesis while simultaneously modulating matrix metalloproteinase (MMP) activity (Pickart & Margolina, Biomedicines, 2018)

That idea has enough biologic plausibility to be interesting

Still, for people with copper-metabolism disorders or with repeated/systemic exposure, copper burden is a real theoretical concern that has not been studied in humans

The peptide forms a stable complex with copper ions, and this GHK-copper combination triggers gene expression changes affecting tissue regeneration , inflammation, and collagen synthesis
