Melanotan I (10mg)

Melanotan I (also called afamelanotide or MT1) is a tanning peptide that tells your skin to produce more melanin — the pigment responsible for skin colour. It works by signalling the same biological pathway that sunlight triggers, but without requiring UV exposure to get there. The result is a deeper, more even tan that builds over days and lasts well beyond the dosing period. It's the focused tanning compound: purely pigmentation, without the libido and appetite effects that come with Melanotan II.

The simplest way to put it: Melanotan I is just for tanning. Melanotan II does tanning plus libido enhancement, appetite suppression, and mood effects. MT1 is laser-focused on melanin production, which means a cleaner experience — no unexpected side effects. MT1 also lasts significantly longer in the body than MT2, so the tan it produces tends to be more sustained. If you specifically want the tan without anything else, Melanotan I is the one.

Melanotan I goes by a few names: afamelanotide (its clinical name), MT1, and MT-1. It's the same compound used in Scenesse — a clinically approved implant used in Europe and the US for people with severe light-sensitivity conditions. If you've been searching for 'MT1 peptide Australia' or 'afamelanotide Australia', you're in the right place.

Your skin contains cells called melanocytes, which produce melanin — the pigment that gives skin its colour. Sun exposure triggers melanin production, which is why you tan. Melanotan I mimics that signal directly, stimulating melanin production without needing UV to kick things off. The melanin builds up in the skin over days, producing a tan that deepens gradually. That extra melanin also acts as a natural buffer against UV — absorbing radiation before it can cause damage — which is why people with higher melanin levels burn less easily.

Melanotan I has a significantly longer half-life than Melanotan II, which means the pigmentation it produces is more sustained. The tan typically continues to develop for several days after dosing and then holds for an extended period — considerably longer than what you'd get from MT2. Individual results vary depending on starting skin tone, dose, and sun exposure during the protocol.

Clinical research has consistently shown strong tanning responses — significant increases in skin pigmentation, longer-lasting colour compared to MT2, and measurable photoprotective benefits (skin with more melanin absorbs more UV before it causes cell damage). Afamelanotide is approved in Europe and the US for a severe light-sensitivity condition called erythropoietic protoporphyria — patients in trials were able to spend substantially more time in sunlight without pain. That clinical track record is what gives MT1 its credibility as a tanning compound.

Melanotan I is supplied as a lyophilized powder and should be reconstituted with bacteriostatic water (BAC water) immediately before use. Inject the BAC water slowly into the vial, directing the stream down the inside wall. Gently swirl to dissolve — do not shake. Once reconstituted, store at 2–8°C and use within 8–12 weeks. For a full step-by-step walkthrough, see our complete peptide reconstitution guide.

Store lyophilized Melanotan I vials at -20°C, protected from light and moisture. After reconstitution with BAC water, refrigerate at 2–8°C and use within 8–12 weeks. Do not freeze the reconstituted solution.
