AHK-Cu is a small copper-binding tripeptide (Alanine-Histidine-Lysine) that forms a stable complex with copper (Cu²⁺). It belongs to the same family of endogenous copper-peptides as GHK-Cu, but its biology skews strongly toward the hair follicle and scalp: preclinical studies show AHK-Cu enlarges the dermal papilla, prolongs the anagen (growth) phase, and stimulates capillary micro-circulation around the follicle.
Researchers use AHK-Cu in topical and intradermal protocols targeting androgenic thinning, telogen effluvium, post-transplant recovery, and general scalp regeneration. It is frequently stacked with GHK-Cu for a full copper-peptide protocol covering skin remodeling, angiogenesis, and hair growth in parallel.
BioPeptideX supplies AHK-Cu as a 100 mg lyophilized powder, ≥99% HPLC verified, sealed under inert atmosphere and shipped with a Certificate of Analysis. Every vial is lot-traceable — for laboratory research use only.
