GHK‑Cu research shows real skin benefits but the hype may be overblown

The article links to a 2015 review on PubMed Central that summarises placebo‑controlled trials of GHK‑Cu creams. It highlights improvements in skin elasticity, density and wound closure in laboratory and small human studies.

I think the paper is solid – it’s peer‑reviewed and the data on fibroblast collagen synthesis are hard to dispute. What worries me is the leap from a topical cream to claims about systemic healing or anti‑ageing miracles. Most of the work is on skin, not tendons or joints, and the doses used in creams are tiny compared with what you’d need for deeper tissue repair. In my own limited trial with a low‑dose topical, I noticed a marginal smoothing of the forearm scar but nothing dramatic for my hamstring strain recovery.

Has anyone tried a higher‑dose oral or injectable protocol and seen any real effect on musculoskeletal injuries, or are the benefits truly limited to surface skin health?
