What is GHK-Cu used for?

GHK-Cu, a naturally occurring copper binding tripeptide, is widely used in skincare for its studied effects on collagen synthesis and skin remodeling, and it is also researched for wound healing. It is not an approved drug; it is permitted as a cosmetic ingredient in the US, UK, Australia, and Canada. This site's review found human evidence limited mainly to topical cosmetic research rather than injectable clinical trials.
