Three names, three different things

Afamelanotide, SCENESSE, and the Melanotan tanning myth
One molecule wears three labels, and telling them apart is the first step in understanding this peptide. Afamelanotide is its clinical name, SCENESSE is the brand of the approved implant, and Melanotan I is the old research name for the same molecule. Separately, unregulated products called "Melanotans" are sold online for tanning.
This unit sets the three categories apart: the approved EPP implant, the off-label clinical uses, and the unregulated products sold for cosmetic tanning. It also separates afamelanotide from Melanotan II, a different compound with a similar name.

Key terms
One molecule, three labels
The story starts in 1980, when chemists reported a stabilized, longer-acting version of the natural hormone alpha-MSH. That molecule is afamelanotide. Over four decades it moved from early tanning studies to an orphan drug, picking up the brand name SCENESSE and earning approval for a rare light-sensitivity disease, erythropoietic protoporphyria (EPP). Knowing this timeline is the first step to telling the real drug apart from its gray-market shadow.
AdvancedWhy the three names confuse people
The approved product is supplied as SCENESSE through the medical system: in Europe it is only prescribed by specialist doctors in recognised centres for treating EPP. Online, unregulated products called "Melanotans" are sold for tanning, and no analysis in this course's sources has confirmed what a product sold as "Melanotan I" contains. A name on a vial therefore tells you almost nothing about quality, route, or oversight, which is why this course anchors on what is actually in the vial.
The three categories, kept apart
Many misconceptions about this peptide come from blending three very different uses into one. The approved implant for EPP rests on randomized trials and regulatory review. The off-label dermatology uses have real but smaller evidence and no approval. The gray-market tanning products have unknown contents and no controlled study behind them in this course's sources. There is a further gap worth naming early: the analyses of online tanning products in this course's sources tested Melanotan II, so nothing here confirms that a product sold as "Melanotan I" actually contains afamelanotide, and even the shared name is an assumption. Holding these apart is the core skill this course builds.
AdvancedWhere the language goes wrong
A phrase like "the FDA-approved tanning peptide" quietly collapses all three categories at once. The approval is for preventing light pain in EPP, not for cosmetic tanning, and the approved product is an implant placed by a clinician, not an injection bought online. Each time you read a claim, ask which of the three categories it actually refers to before deciding whether it is true.
What afamelanotide actually is
Strip away the branding and afamelanotide is a 13-amino-acid peptide, a near-copy of the body's own alpha-MSH with two deliberate tweaks. Those changes are reported to make it more potent, more resistant to breakdown and longer-acting than the natural hormone. One of them sits inside the His-Phe-Arg-Trp sequence that reviews postulate as the melanocortin recognition sequence: the phenylalanine there is switched to its mirror-image D-form, giving His-DPhe-Arg-Trp. Click each residue below to see how the chain is built and where the two key substitutions sit.
The honest evidence picture
Before any deeper science, here is the honest ceiling. For EPP, afamelanotide rests on randomized placebo-controlled trials, two of them pivotal, and years of observational follow-up. For vitiligo it has a published randomized trial, run alongside phototherapy, but no approval. For solar urticaria the evidence drops to a five-patient pilot, and cosmetic tanning is not an approved use at all. Reading each claim against its true tier, rather than against how confidently it is stated online, is what separates honest education from marketing copy.
This course is education, not medical advice. SCENESSE is a prescription implant placed by a clinician, and nothing here endorses cosmetic tanning use.
AdvancedHow to read these tiers
The tiers are not a ranking of how popular a use is, but of how much controlled human evidence supports it. The approved EPP use sits on randomized trials and long registries, while the gray-market tanning use rests on anecdote. When a source promotes tanning by pointing to the EPP approval, it is borrowing credibility from a tier the tanning claim has not earned.
Popular claims, checked
A few specific claims you will meet online, held against the evidence. Notice the pattern: the statements are not always false, but they smuggle the gray-market tanning use in under the approved drug's reputation, or they borrow Melanotan II's effects and pin them on afamelanotide. Each one is really a category error in disguise, and naming which category it confuses is usually enough to defuse it.
