Melanotan II · α-MSH Analog · Tanning, Libido & Body Comp
A deep, natural-looking tan with barely any sun. Melanotan II gets your skin producing its own colour — and most people notice a nice libido bump too.
Melanotan II is the "tan without the sun" peptide. It switches on the cells that make melanin, so your skin develops real colour with far less UV exposure than natural tanning would need — and because it also touches a second receptor, most people notice a libido bump along the way.
Colour usually starts showing after about five doses and holds for weeks after you stop, which is what the lighter maintenance schedule keeps up. Early on, expect some day-one nausea, flushing, and yawning that fade as your body adjusts. Be honest with yourself here: it's unregulated, and because it can darken moles, keep a close eye on your skin and start at the low end.
Small human studies Studied in people, but in small groups rather than large trials.
Most people land at 0.5 mg · Every evening.
That is where most people settle, not a number you have to reach. The right dose is the lowest one that is doing the job — when it is working, you stop climbing. Plenty of people sit a step or two below the top and stay there for good, and there is nothing second best about that.
The routes below are three ways up, not three different destinations. Most people take Steady. If you have had a rough time with medication before, or you would simply rather ease in, take one of the slower ones — going up more slowly has not been shown to cost results. Holding at a step because a week was hard is a normal part of this, not falling behind. Each row gives you the dose and exactly what that is on the syringe.
A week at half, then the full dose · top step by week 2
| Week | Dose | 10 mg vial |
|---|---|---|
| 1 | 0.25 mg | 5 units |
| 2+ | 0.5 mgtop step | 10 units |
Three weeks at the half dose before you step up · top step by week 4
| Week | Dose | 10 mg vial |
|---|---|---|
| 1–3 | 0.25 mg | 5 units |
| 4+ | 0.5 mgtop step | 10 units |
Below 0.25mg the draw is 2 units, which is too small to measure reliably, so this route gives you more time at the half dose rather than a smaller one. First-hour flushing and nausea are worst on the first few doses and fade quickly.
A lot of people take it every other evening for the first week rather than nightly. It spaces out the doses your body is least used to, and it is the single easiest thing to do if the first one hits you hard.
Mixing: 10 mg + 2 ml → 5 mg/ml. Add the water slowly down the inside of the glass and roll it — never shake it. Keep it in the fridge at 2–8 °C once mixed. Units above are on a standard U-100 insulin syringe.
Nausea, flushing and a stretchy feeling in the first hour, mostly in the first week. Dosing in the evening means you sleep through most of it.
How long: 4 weeks–8 weeks
Break: 4 weeks
Every batch is independently assayed before it is sold, and the lab measures how much peptide is actually in the vial — not just how pure it is. The most recent batch tested here came in 5% over the labelled amount. That is deliberate: we would rather you got more than you paid for than less.
