Things worth knowing about "Melanotan"

Melanotan is a synthetic peptide hormone that stimulates skin tanning. It is not approved for medical use and carries significant health risks.

What is Melanotan?

Melanotan refers to two synthetically produced peptides – Melanotan I (afamelanotide) and Melanotan II – originally developed in the 1980s at the University of Arizona. Both compounds are analogues of the naturally occurring alpha-melanocyte-stimulating hormone (α-MSH), which regulates melanin production in the skin. While Melanotan I is medically approved under strict conditions in some countries for a rare photodermatosis, Melanotan II has no approved medical use in the EU or the United States and is sold illegally.

Mechanism of Action

Melanotan peptides bind to melanocortin receptors, particularly the MC1 receptor on melanocytes (pigment-producing cells of the skin). This binding stimulates the synthesis of melanin, the natural pigment responsible for darkening the skin. Melanotan II additionally binds to other melanocortin receptors (MC3R, MC4R, MC5R), which explains a range of unwanted side effects, including appetite suppression and sexual arousal.

Use and Distribution

Melanotan is primarily used by individuals seeking an artificial skin tan without sun exposure or tanning beds. It is most commonly offered as a subcutaneous injection (injected under the skin) or as a nasal spray. The purchase and possession of Melanotan II is illegal in Germany and the EU. Products are frequently sold via the internet with uncontrolled quality, introducing additional risks from contamination.

Medical Approval

Melanotan I (active substance: afamelanotide) is approved in the EU under the trade name Scenesse exclusively for the treatment of Erythropoietic Protoporphyria (EPP), a rare genetic disorder causing extreme light sensitivity. It is administered as a subcutaneous implant under medical supervision.

Melanotan II has no medical approval in Germany, the EU, the United Kingdom, Australia, or the United States for any indication.

Side Effects and Risks

Melanotan products – especially Melanotan II – can cause significant side effects:

Short-term side effects: nausea, vomiting, facial flushing, dizziness, fatigue, spontaneous erections in men
Skin changes: new or altered moles (nevi), which may indicate an increased risk of melanoma (skin cancer)
Cardiovascular risks: changes in blood pressure, palpitations
Psychological effects: mood changes, in some cases depressive episodes
Infection risks: non-sterile injections can lead to infections, abscesses, or transmission of pathogens
Unknown long-term effects: as no controlled long-term human studies exist, the long-term risks remain largely unknown

Legal Status

Melanotan II is an unapproved medicinal product in the EU and many other countries. Its purchase, possession, and distribution are illegal. Authorities such as the European Medicines Agency (EMA), the U.S. Food and Drug Administration (FDA), and the UK Medicines and Healthcare products Regulatory Agency (MHRA) have issued explicit warnings against its use. Consumers are advised not to purchase or use Melanotan II under any circumstances.

When to Seek Medical Advice

If you have used Melanotan and notice side effects such as changing moles, unexplained skin changes, heart palpitations, persistent nausea, or other concerning symptoms, seek medical attention immediately. Inform your doctor that you have used Melanotan so that appropriate diagnosis and treatment can be provided.
