Community-reported ranges are anecdotal and not clinically validated. Evidence grade shown reflects the strength of available human data. Not a prescription. Legal status varies by country and changes over time; verify locally.

Overview

A melanocortin-receptor agonist that reliably produces tanning with minimal UV, plus reported libido and appetite effects — it works, which is exactly why its risk profile matters. Documented adverse events (darkening moles, blood-pressure effects) and rapidly tightening legal status make it one of the highest-risk entries in this library.

Mechanism

Non-selective melanocortin-receptor agonist increasing melanogenesis, with off-target effects on libido, appetite and cardiovascular tone from the same receptor family.

Evidence

Animal / preclinicalWhat does this mean?

Tanning efficacy is well established anecdotally, but safety is poorly characterised, adverse events are documented, and regulators in several countries have moved against it.

Frequently asked questions

Is Melanotan II safe?
This is one where the honest answer is genuinely cautionary: it clearly works for tanning, but safety is poorly characterised, adverse events including mole changes are documented, and regulators warn against it — which is why Aminove doesn't present dosing information for it.
Is Melanotan II legal?
It is not approved for human use; the UK MHRA has warned against it, and in Australia it became a Schedule 9 prohibited substance in 2026.
How is Melanotan II different from afamelanotide?
Afamelanotide (Scenesse) is an approved, clinic-administered implant for a rare disease; Melanotan II is an unapproved grey-market product. They are not interchangeable.
