GHK-CuClinical (topical) evidence

Copper peptide

A naturally occurring copper-binding tripeptide, researched mainly as a topical skin-regeneration, anti-aging and wound-healing agent.

⚙️ How it works

Delivers copper into cells and acts as a broad gene-expression modulator, shifting thousands of genes toward a repair profile. Stimulates fibroblasts and upregulates collagen, elastin and proteoglycans while balancing matrix metalloproteinases; also antioxidant and anti-inflammatory.

🎯 What it's studied to help

Bars reflect the strength & volume of research evidence for each use — not a guarantee of results.

Skin68/100
Boosts collagen/elastin synthesis; a human study found collagen increases in ~70% of users.
Hair40/100
Influences follicle signalling with cosmetic data for follicle size, though weaker than its skin evidence.
Reduces inflammatory mediators (e.g. TNF) and oxidative damage in wound models.
Supports ECM/repair pathways relevant to connective tissue, but direct joint evidence is sparse.
