PepEvolutionAHK-Cu
A copper tripeptide with a hair-regrowth signal in limited studies — well-tolerated, but the human evidence base is thin.
Verdict — C · Emerging / Mixed
Mechanistically plausible and well-tolerated, but the human evidence base for AHK-Cu specifically is thin. A C-grade cosmetic peptide for the informed buyer; do not expect the evidence base of minoxidil or finasteride.
Overview
AHK-Cu (Ala-His-Lys copper chelate) is a synthetic copper tripeptide with proposed hair follicle-stimulating activity, primarily studied as a topical ingredient for androgenic alopecia. In-vitro and limited ex-vivo studies suggest effects on follicle cell proliferation. Human clinical data are sparse; the primary evidence base is proprietary cosmetic studies. The safety profile is favorable given its similarity to other copper tripeptides, but the evidence is thin relative to established hair-loss treatments.
