Cyclic non-selective melanocortin agonist (research)
Melanotan-2
Cyclic α-MSH analogue with MC1R tanning activity plus more MC3/MC4 effects (appetite, sexual signalling, autonomic) than Melanotan-1.
Primary Mechanism of Action
Clinical / Scientific
Melanotan-2 is a cyclic analogue with broader - activity than MT-1, hence pigmentation plus central effects (nausea, appetite, sexual signalling). It is not a licensed tanning medicine.
Pathway Targets
MC1 receptor
Scientific explanation
Melanogenesis.
MC3/MC4 receptors
Scientific explanation
Central autonomic and sexual signalling (less selective than MT-1).
Pathway Convergence
Clinical / Scientific
Target → pathway → downstream effect → biological consequence. This is a mechanistic map, not a treatment claim.
Receptor to physiology
Target to downstream effect: MC1 receptor → MC3/MC4 receptors

Research peptide context
PreclinicalMechanistic rationale
Catalogued as a research peptide. Mechanistic statements below describe known or pathway biology and do not establish a licensed therapeutic indication.
Mechanistic Application Matrix
| Biological Target | Mechanism | Potential Relevance | Evidence Level |
|---|---|---|---|
| MC1R | Agonism | Pigmentation | Established mechanism |
| MC4R | Agonism | Central side-effect profile | Established mechanism |
Mechanistic Interaction Considerations
Blood-pressure, nausea, and priapism-like reports exist in unregulated use series. Not interchangeable with inhibitors.
In Plain Language
Melanotan-2 tans via MC1 receptors but also hits other receptors in the brain, which is why extra effects (and side effects) show up more than with Melanotan-1.
