AHK-Cu is a synthetic tripeptide-copper complex consisting of the amino acid sequence Ala-His-Lys bound to a copper ion. It is studied primarily for its potential effects on hair growth and skin regeneration. The copper-peptide complex is believed to support tissue remodeling and cellular proliferation through various signaling pathways.
Typically applied topically in research settings at concentrations ranging from 0.1 to 10 μM in hair growth studies. In vitro research protocols commonly use 1-5 μM concentrations for cell culture applications. Application frequency varies by formulation and research objective.
AHK-Cu promotes hair growth through multiple pathways including stimulation of vascular endothelial growth factor (VEGF) expression, enhancement of dermal papilla cell proliferation, and modulation of transforming growth factor-beta (TGF-β) signaling. The copper ion component facilitates enzymatic activities involved in extracellular matrix remodeling and angiogenesis, while the tripeptide sequence provides cellular signaling functions.

AHK-Cu has an approximate half-life of Not well-characterized; topical applications show local tissue retention. The half-life determines how often you need to inject to maintain steady blood levels — use the Peptides Calculator half-life calculator to plot your specific dosing schedule and see the decay curve.
AHK-Cu is typically delivered via topical application. The Peptides Calculator app helps you reconstitute the vial with bacteriostatic water, calculate your exact dose in syringe units, and track each injection.
