GHK-Cu
GHK-Cu, the copper peptide behind real skin science.
GHK-Cu is the copper peptide with actual cosmetic and dermatology data behind it. PepEasy is where you learn what it does, then calculate and track it with confidence.
Educational only — not medical advice. PepEasy never recommends a dose.
GHK-Cu is a naturally occurring copper-binding tripeptide (glycine-histidine-lysine) that delivers copper to cells and is widely used in topical skincare for skin remodeling and recovery. PepEasy is where you learn how it works, ask grounded questions, and calculate and track it accurately. We educate; we never diagnose, prescribe, or recommend a dose.
Why GHK-Cu stands out
Among peptides, this one is unusual: it has real human cosmetic studies, not just folklore.
A natural copper carrier
A tripeptide found in human plasma that binds copper and shuttles it into cells — levels decline with age.
Skin remodeling
Studied for stimulating collagen, elastin, and glycosaminoglycan production in dermal fibroblasts.
Real topical data
Small controlled facial studies report anti-wrinkle and firming effects — rare among peptides.
Recovery signaling
Strong animal wound-healing data and growth-factor signaling drive its recovery reputation.
