What AHK-Cu is
A copper tripeptide marketed as the hair-growth cousin of GHK-Cu; in-vitro stimulation of hair follicle cells only, with no human trial.

Mechanism: Copper-peptide stimulation of dermal papilla cell proliferation and VEGF expression (in vitro).
Regulatory history: Cosmetic ingredient; not a drug
How MHRA treats this kind of product
Licenses medicines for the UK market. A compound without a marketing authorisation is an unlicensed medicine, which can only lawfully be supplied for human use through a prescriber under the specials scheme, not sold as a research product.
The classification above is the The Longevity Archive reading of Medicines and Healthcare products Regulatory Agency listings for AHK-Cu at the reviewed date, not a legal opinion. Rules change, and importing, prescribing and possessing a compound can each be treated differently. Check the regulator directly before acting on anything here.
