No study in this site's review has linked topical GHK-Cu to cancer, and it is permitted as a cosmetic ingredient in the US, UK, Australia, and Canada, a status that reflects an established safety record in that use. Copper's biological role is complex, but this site's citation review found no human clinical trial for GHK-Cu that reported cancer as an outcome.
