Melanotan-1 — EU research guide.

Melanotan-1 (afamelanotide) is a synthetic analogue of alpha-melanocyte-stimulating hormone (α-MSH) that selectively activates MC1R, increasing melanin production. It is EMA-approved as Scenesse for erythropoietic protoporphyria.

Last reviewed:

What is Melanotan-1?

Melanotan-1 (afamelanotide) is a linear α-MSH analogue with a Nle4 and D-Phe7 substitution that selectively activates MC1R — the receptor on melanocytes that drives eumelanin (brown/black pigment) synthesis. Unlike Melanotan-2, it does not significantly activate MC3R or MC4R, avoiding the sexual and appetite effects of MT-2.

What does the research show?

Afamelanotide received EMA approval in 2014 as Scenesse for preventing phototoxic reactions in adults with erythropoietic protoporphyria (EPP). In clinical trials it significantly increased pain-free sun exposure time. Research also explores photoprotection in other photosensitivity disorders, xeroderma pigmentosum and solar urticaria.

EU legal status

EMA-approved as Scenesse (Clinuvel) for EPP — prescription only. Research-grade Melanotan-1 sold by research vendors is not the approved pharmaceutical and is for laboratory research only. The approved drug is a subcutaneous implant; research-grade forms are typically lyophilised powder.

EMA-approved Rx medicine exists (Scenesse for EPP). Research-grade MT-1 is not the approved pharmaceutical. Do not substitute research-grade for the approved drug. Not for human use in research context. This is a research compound, not a medication.
✓ PeptideCompare lists research-grade Melanotan-1 from EU vendors. Distinguish clearly from Melanotan-2 — different receptor profile and legal status.
EVIDENCE SUMMARY
STRONG
Melanogenesis & photoprotection — MC1R agonist with robust, dose-dependent skin pigmentation; the basis of the approved analogue afamelanotide.
MODERATE
UV-independent tanning — Stimulates melanin synthesis with reduced UV exposure in human studies.

Frequently asked questions

What is Melanotan-1?

Melanotan-1 (afamelanotide) is a linear alpha-MSH analog with Nle4 and D-Phe7 substitutions that selectively activates MC1R, the melanocyte receptor that drives eumelanin synthesis.

How is Melanotan-1 different from Melanotan-2?

Unlike MT-2, it does not significantly activate MC3R or MC4R, so it avoids the sexual and appetite effects of MT-2 while still driving pigmentation.

What does the research show?

Afamelanotide received EMA approval in 2014 as Scenesse for preventing phototoxic reactions in erythropoietic protoporphyria, significantly increasing pain-free sun exposure time. Research also explores other photosensitivity disorders.

Is Melanotan-1 approved in the EU?

Yes. It is EMA-approved as Scenesse (Clinuvel) for erythropoietic protoporphyria on prescription, and research-grade material is also available for laboratory use.

What is Melanotan-1 used for medically?

As Scenesse it is used to prevent phototoxic reactions in adults with erythropoietic protoporphyria, with research into xeroderma pigmentosum and solar urticaria.

Is Melanotan-1 banned in sport?

It is not currently on the WADA prohibited list.
