AHK-Cu
AHK-Cu
Also known as: Copper Peptide AHK-Cu, AHK Copper, Tripeptide Copper AHK
Overview
Key Facts
Primary Goal: A copper-binding tripeptide structurally related to GHK-Cu but with distinct receptor binding properties
A copper-binding tripeptide structurally related to GHK-Cu but with distinct receptor binding properties. AHK-Cu has been shown to be a particularly potent stimulator of hair follicle growth, outperforming both GHK-Cu and minoxidil in certain in vitro models. It also promotes collagen synthesis and wound healing, though its primary cosmetic interest lies in hair restoration. Half-Life ~1-2 hours Typical Dose 0.5–2 mg Frequency Once daily (topical to scalp or skin) Cycle Length 8-16 weeks continuous use for hair growth assessment

Research Summary
Research published in the Journal of Biological Chemistry and related journals demonstrated that AHK-Cu stimulates dermal papilla cell proliferation more effectively than GHK-Cu at equivalent concentrations. A 2007 study showed that AHK-Cu increased hair follicle size and prolonged the anagen (growth) phase in organ culture models. While clinical trial data in humans remains limited, its mechanism of action through copper delivery and Wnt pathway activation makes it a promising candidate for alopecia treatment.
