GHK-Cu
Research compoundaka Copper Peptide, Copper tripeptide-1
Copper peptide. A skincare staple for collagen and repair, and the one cosmetic peptide that actually earns its reputation.
Mechanism
A copper-binding tripeptide your body already makes. It drives collagen synthesis, mops up oxidative damage, and helps skin heal. Topically it's well studied and it genuinely works.
Regulatory & Safety Status
Topical use in cosmetics is fine and well tolerated. Injecting it is off-label, research-only territory and a completely different risk profile.
