Copper accumulation is theoretically possible with long-term, high-dose use, particularly in individuals with genetic copper metabolism disorders like Wilsons diseasethough the copper content in therapeutic GHK-Cu doses is minimal compared to dietary intake
5), and by inference, neurotoxic damage.53 Forgione and colleagues had previously hypothesized that GPX1 deficiency directly induces an increase in vascular oxidative stress, with attendant endothelial dysfunction.54 Glutathione peroxidases, particularly GPx1 have also been implicated in the development and prevention of many common and complex diseases, including cancer and cardiovascular disease (Fig
