What is Melanotan III?
Plain language first. The technical label stays, but it never stands alone.Overview
A third melanotan that vendors sell and nobody has described. If a seller offers it, ask which molecule is in the vial and what its mass is.
No molecule corresponding to the designation Melanotan III is characterized in public sources. Melanotan I (afamelanotide) and Melanotan II are both documented with sequences and regulatory histories. This entry records the absence rather than inferring a structure from the name.
What it's used for
A name sold as a third melanotan. No published characterization of the compound exists.
How does Melanotan III work?
What it does in the body, and where.The melanotan family has two members with a published history, and this is not one of them.
- 01Melanotan I and II are real and documentedMelanotan I is afamelanotide, approved as Scenesse. Melanotan II is a cyclic heptapeptide from the University of Arizona work, and PT-141 came out of it. Both have sequences, patents and trials.
- 02No comparable record exists for a thirdSearches of published literature, patent filings and supplier technical sheets turned up no sequence, formula or molecular weight for anything called Melanotan III.
- 03The pattern is familiarA number that continues a known series is an effective product name whether or not a distinct molecule sits behind it. GHRP-3 sits in the same position in its own family.
What else is it used for?
Each use below carries its own evidence level. Approved means regulators have cleared it for that purpose. Investigational means it is in trials. Early research means it is being studied and is not established.

Four things to know about Melanotan III
How much, and do you cycle it?
The range, and whether you take breaks.Research only, not established. Not established No range
No schedule has been studied for this compound in people.
Nothing publishedNo figure
No half-life can be published for a compound with no established identity.
You can compare this against the whole library to see where it sits.
How do I dose and price it?
Enter your vial and your dose. Pick a mix. We show the draw and the cost.The vial holds a fixed amount of drug. Adding more water does not make more drug, it just spreads it thinner, so you draw a bigger number on the syringe for the same dose.
Choose your mix
Measuring the water1 mL = one full 100-unit syringe.
How do you store it?
Before mixing, and after.Dry powder in the freezer or fridge. Once mixed, fridge, and use within about a month.
Unmixed lyophilized Melanotan III keeps for a long time cold. Once you add water the clock starts: most reconstituted vials hold up for roughly 28 to 30 days at fridge temperature. Keep it out of light, and do not freeze it after mixing.
What are the side effects and cautions?
Known cautions and warnings for this compound.Who should avoid it
- Pregnancy or breastfeeding
- Any history of skin cancer, atypical moles, or a family history of melanoma
- Anyone unable to confirm from a certificate of analysis what molecule they have
- Anyone who wants established safety data, because none exists for this compound in humans
Stop and get help
- A mole that changes in size, shape or color, which needs urgent assessment
- Signs of an allergic reaction, including facial or throat swelling or trouble breathing
- Anything unusual, since there is no known safety profile to compare it against
Common effects
- Unknown. No study has recorded what this commonly causes, because the compound is not identified
