GHK-Cu (Gly-His-Lys-Cu, 404 Da) acts via copper coordination and modulates ~4,000 genes related to tissue repair, collagen synthesis, and antioxidant defense
Immune signaling also touches skin repair, since inflammation can slow collagen repair and can push hairs into a rest phase after illness or infection

A valid prescription from a licensed healthcare provider is required
This can lead to reduced muscle tone, slower recovery, and visible signs of aging
