GHK-Cu affects over 4,000 human genes according to research, with particularly strong influences on genes related to tissue remodeling, antioxidant protection, and cellular regeneration
It can be recycled back to methionine through remethylation or irreversibly directed into transsulfuration to produce cysteine and downstream sulfur compounds
