Copper Peptide AHK-Cu
AHK-Cu / Alanine-Histidine-Lysine Copper / Hair Growth Peptide
A tripeptide-copper complex (Ala-His-Lys-Cu) structurally related to GHK-Cu but specifically researched for hair follicle stimulation. Promotes hair growth by increasing follicle size, stimulating proliferation of dermal papilla cells, and enhancing growth factor expression (VEGF, FGF). Used in topical hair regrowth formulations, often combined with minoxidil or finasteride.

Evidence Overview
Strength of evidence across clinical, expert, and experimental lanes.
How Copper Peptide AHK-Cu is dosed in practice
Usually taken on the skin. Typical range: Topical solution — typically 50–100 ppm in carrier. Half-life: N/A (topical application). Each card gives the dose, frequency and duration from one evidence lane: Clinical (human trials), Expert (practitioner protocols) or Experimental (early or animal data). These ranges describe what has been studied or used; they are not a prescription.
Work out the units to draw with the reconstitution calculator, how long a vial lasts with the vial duration calculator, and how levels fall between doses with the half-life calculator.
Hair loss community combines AHK-Cu with microneedling and minoxidil for enhanced absorption and efficacy. Some users add it to custom topical formulations from compounding pharmacies. Results take 3–6 months and are most noticeable in early-stage hair thinning. Often preferred over GHK-Cu specifically for hair applications.
