peptide for skin ghk-cu GHK Copper | firms skin GHK-Cu Peptide for Skin Rejuvenation

Rat studies using collagen tubes containing GHK-Cu showed increased nerve fiber regeneration, increased axon count, increased Schwann cell proliferation, and restored skin innervation in healing wounds

In earlier trials, researchers tested a range of doses from 0.3 mg up to 4.5 mg

The growth hormone receptor upregulation mentioned earlier proves particularly relevant for tendons

Use lightly at first

Researchers studying metabolic stress often pair this combo with SS-31 (Elamipretide), which targets mitochondrial function and oxidative stress pathways

GHK-Cu stimulates fibroblasts and the synthesis of collagen, elastin, glycosaminoglycans, and other matrix components, and it supports the copper-dependent enzymes that crosslink connective tissue
