Glutathione contains sulphur molecules so sulphur rich diet increases natural production
Research overwhelmingly describes the safety of GHK-Cu positively, such as when the authors of a 2018 review called it a safe, inexpensive, extensively studied compound.14 However, even though copper peptides have demonstrated an impressive safety track record in studies, there are (as with most skin care actives) a few safety risks to consider
2.2 Antioxidant and Anti-Inflammatory Effects: As a copper chaperone, GHK-Cu activates superoxide dismutase (SOD), neutralizing reactive oxygen species (ROS) and protecting against oxidative damage
I have been covering peptide research for over six years now, and GHK-Cus collagen data is among the most impressive I have seen for any single compound
That is, however, clearly within the medical realm because of glutathione side effects and liability for abuse
