GHK Cu Injectable Team Wellcore A year ago I started working with a copper peptide called GHK Cu. Topically every night. And under my doctor's care, I went deeper than topicals with a low dose. The difference in Before vs. after 3 months of GHK Cu peptide therapy smoother texture, more even tone, and skin that looks healthier overall.
