Melanotan UK legal status
Melanotan I and Melanotan II have one of the clearest UK regulatory positions of any peptide: they are unlicensed, the MHRA has warned against them repeatedly, and the documented safety profile is poor.
Current UK regulatory framing
Melanotan I (afamelanotide) and Melanotan II are synthetic analogues of alpha-melanocyte stimulating hormone (α-MSH). Neither is a UK-licensed medicine for cosmetic use.
Note: afamelanotide (Scenesse) is licensed in the UK and EU for the very narrow indication of preventing phototoxicity in adults with erythropoietic protoporphyria (EPP) — a rare inherited condition. That specialist licensed use is not what is being sold in the consumer melanotan market.
The MHRA position on consumer melanotan products has been consistent for over a decade: they are unlicensed, the supply is unlawful, and the safety profile is unacceptable for cosmetic use.
What MHRA has done
- Repeated public-health warnings against use, including warnings specifically about nasal-spray formulations and injectable vials.
- Seizures and supply-chain disruption.
- Prosecutions of online sellers (some publicised, many handled without press release).
- Work with social-media platforms and payment processors to disrupt the sales infrastructure.
Documented adverse effects
- Skin lesions and mole changes. New moles, mole darkening, and changes that have led to melanoma diagnoses are documented in case reports.
- Severe GI effects. Nausea, vomiting, and flushing are common; severe episodes have led to hospital admissions.
- Cardiovascular effects. Hypertension, chest pain, and arrhythmias have been reported.
- Sexual side effects. Spontaneous erections in men are well-documented (the basis for PT-141 development).
- Kidney injury and rhabdomyolysis in severe cases.
What lawful supply looks like (it doesn't, for cosmetic use)
There is no lawful UK route to obtain melanotan for cosmetic tanning. Any seller offering it is doing so unlawfully. There is no “research only” carve-out that resolves the regulatory analysis; see ‘not for human consumption’ claims.
The narrow licensed afamelanotide / Scenesse supply for EPP runs through specialist NHS centres on a controlled-access basis. It is not available to consumers and is not what the cosmetic melanotan market is selling.
Sport
Melanotan does not appear by name on the WADA Prohibited List, but as a non-approved substance it falls under S0. Athletes face strict-liability sanctions; the “I used it for tanning” defence is not available.
Red-flag claims
If you see wording like this on a seller, clinic, or social-media advert, treat it as a warning sign rather than a benefit.
“Melanotan II nasal spray — UK seller, fast delivery”
Unlawful supply of an unlicensed medicinal product. Nasal-spray formulations have been a specific MHRA target.
“Research-grade melanotan — for laboratory use only”
The disclaimer does not change the medicinal-product analysis. Sold to consumers with dosing instructions, this is unlicensed-medicine supply.
“Bronze without sunbeds — natural tan in 2 weeks”
Cosmetic claim for an unlicensed substance with a documented safety record including melanoma case reports.
“Used by influencers — see real before/after”
Influencer promotion of an unlicensed medicine engages both ASA and MHRA jurisdiction.
“Safer than tanning beds”
Comparative safety claim for a product the MHRA has issued repeated warnings against. Tanning beds are also harmful — this isn't a comparison that helps.

Frequently asked questions
- Is melanotan legal to sell in the UK?
- No. Melanotan I and Melanotan II have no UK marketing authorisation. Selling them is supplying an unauthorised medicinal product, which is an offence under the Human Medicines Regulations 2012. The MHRA has issued repeated public-health warnings and prosecuted suppliers.
- Is it legal to use melanotan personally?
- Personal possession for individual use is not, on its own, the primary enforcement target — but the safety risks (mole changes, skin lesions, kidney issues, gastrointestinal effects) are documented and serious, and the supply chain you'd buy from is unlawful.
- What has the MHRA actually said?
- MHRA has run repeated public-health campaigns warning against melanotan use, citing both the unlicensed-medicine status and the safety profile. Nasal sprays and injectable vials have both been seized and supply chains disrupted.
- Is it on the WADA Prohibited List?
- Melanotan does not appear by name, but as a non-approved substance it falls under S0 of the WADA Prohibited List. Athletes face strict-liability sanctions if it appears in a sample.
- What's the safe alternative if I want a tan?
- Self-tanning lotions, gradual tanning moisturisers, professional spray tans, or simply not tanning. The MHRA, NHS, and dermatology bodies all advise against melanotan because the safety record is poor and there is no licensed alternative.
