Saito, T

GHK-Cu remains one of the more effective non-hormonal options for this group

Human trials have predominantly used topical or brief systemic dosing, and tolerability is overall reported to be good

The study showing copper peptides increased collagen in 70% of users versus 40% for retinoic acid suggests copper peptides may actually be more effective for collagen building specifically, though retinoids offer additional benefits (texture improvement, dark spot reduction) that copper peptides don't provide as strongly

GHK-Cu (Copper Peptide) is a lyophilized research peptide synthesized in the United States, lyophilized in sterile vials, and verified by HPLC and mass spectrometry to greater than 99% purity
