GHK‑Cu: A Skin‑Repair Peptide That Might Help More Than Just Wrinkles
Posted by casey613 in Healing & Recovery - 1 points, 0 comments.
The review from the NIH PMC site looks at GHK‑Cu, a tiny copper‑bound peptide that has been in the lab for over five decades. It shows evidence that topical GHK‑Cu can boost collagen, reduce inflammation, and accelerate wound closure in animal models and a handful of human skin trials.
I’m intrigued by the data, but I’m not fully sold. The human studies I’ve seen were short‑term, small, and mostly cosmetic. In my own post‑training recovery, I’ve never used GHK‑Cu topically, so I don’t know if the skin benefits translate to tendon or joint healing. The article also glosses over potential dose‑response curves and the fact that systemic absorption seems minimal – so it may not reach deeper tissue layers where muscle or ligament repair happens.
Do any of you have tried GHK‑Cu for a non‑skin injury, like a torn tendon or a sore joint, and seen any real difference? If so, what concentration did you use and over how many weeks?
