GHK‑Cu skin serum: my 6‑week experience and questions

Posted by grace_sleepnerd in Longevity & Anti-Aging - 2 points, 0 comments.

I started using the copper peptide serum at age 38 after reading that GHK‑Cu drops collagen and gives a quick skin boost. I mixed 1 ml of 1 mg/ml into my night routine, two times a day, for six weeks. The first week I had a faint tingling and a little redness around my cheeks, but that faded by week three.

After that, my skin felt firmer, the fine lines around my eyes got a bit lighter, and my post‑workout soreness in the joints seemed to clear up faster. I wonder if the topical dose is enough or if a few micro‑injections 1–2 × per week would speed things up. No severe side effects, just mild irritation. I’d love to hear if anyone’s used a higher concentration or a combination with GHK‑Basic for a more pronounced effect.
