Melanotan 2 Dosage: What the Small Studies Used
Early studies tested a few amounts in men and animals. No amount has been approved for people.
Do these research amounts guide your use?
Arizona researchers made Melanotan 2 for study, not home use. This page records amounts from old research. It isn't a dosing guide, and no human amount has approval. Nothing here tells you how much to take.
The papers used milligrams or micrograms, which are small measures of weight. They adjusted the amount for each person or animal's body weight. Put simply, the amount rose when the person or animal weighed more. The two Melanotan 2 studies in people were early safety tests. An amount tested in an animal can't tell you what a person could use.
What amounts did human Melanotan 2 shots contain?
Only two early safety studies gave Melanotan 2 to people. Both used shots just beneath the skin. Neither found an approved dose.
- Tanning study, Dorr and others, 1996: three healthy men began at 0.01 milligrams of drug for every kilogram they weighed. The amount rose to 0.025-0.03 milligrams for every kilogram per day. For two weeks, a shot was given on every other weekday. For later early-stage work, researchers proposed a daily amount of 0.025 milligrams per kilogram. At 0.03 milligrams per kilogram, sleepiness became too strong [4].
- Erection study, Wessells and others, 1998: 10 men received one Melanotan 2 shot containing 0.025 milligrams for every kilogram they weighed, or a placebo [5].
These two studies are the whole controlled human record. No later trial meant to test benefit or confirm safety has been completed. You don't have a sound result for any amount beyond these small studies [3].
Why do the animal amounts not apply to you?
The animal studies used very different amounts and methods. Each study also asked a different question. Those results give you no usable amount for a person.
- Hunger in mice: researchers placed a tiny lab amount straight into brain tissue involved in food reward [6].
- How fast it left rats: the compound went into a vein, after which researchers checked the blood [48].
Only mice and rats took part in this work. Putting a compound into the brain or a vein is unlike ordinary human care. You can't use any of these animal findings as a human dose.
What does melanotan 2 half life tell you?
No sound study has timed how long Melanotan 2 stays in human blood. In rats, blood levels fell fast and did so in more than one stage [48]. A human study instead timed a separate related drug [49]. That work doesn't give you a human Melanotan 2 half-life.
Skin color can outlast the compound in the blood. Once the tanning process starts, your skin may keep adding brown pigment. This helps explain why the tan may remain long after the drug is gone. Any Melanotan 2 half-life figure comes from rats or from another drug, not a human study of this compound.
How did researchers give the compound?
Reports outside approved care mention nose sprays and swallowing the compound. Studies used shots beneath the skin, into veins, or directly into the brain. After rats swallowed Melanotan 2, only about 4.6% reached the body [43]. None of these facts is a how-to.
Researchers used freeze-dried powder, meaning the water had been removed. The ring shape helped slow the body's breakdown of the compound. The study paper also describes lab traits of the powder [43]. Those details don't tell you how to prepare or use it.
