SKIN & SEXUAL HEALTH RESEARCH

Melanotan-2

Studied for stimulating tanning and for its effects on sexual arousal.

Melanotan-2 (MT-2) copies alpha-MSH, the natural hormone that tells skin cells to produce pigment. It is studied for stimulating tanning and for activating the brain's sexual-arousal pathways. It is widely used in the research community, though its evidence base rests on mechanism and real-world use rather than formal human trials.

Why BLP features Melanotan-2

Included because it has a clear melanocortin mechanism and an established real-world use following, shown transparently through its Established Use score. Formal human clinical trials are essentially absent, so its research maturity is Experimental—popularity is shown without being treated as evidence.

Mechanism

A potent copy of the body's own pigment-signaling hormone, increasing production of eumelanin, the dark pigment.

Binds the MC4R receptor in the brain, the switch associated with sexual arousal and appetite suppression.

Described as producing tanning effects with less UV exposure, even at low doses.

WHAT THE RESEARCH MEASURED

Research findings

Findings describe study outcomes, not expected personal results.

Reported research findings

  • No established formal human clinical trials define efficacy or safety; reported effects come from mechanism and research-community use.
  • Reported visible tanning within a few doses across skin types.
  • Reported stronger libido and arousal effects in research use.
  • Flushing, warmth, and possible nausea reported in the first few doses; existing moles/freckles may darken.

Preclinical findings

  • Melanocortin mechanism characterized in pharmacology research.
  • Pigmentation and arousal effects documented in preclinical and use-based settings.

Regulatory status

Melanotan-2 is investigational with no established formal human clinical trials. Sold and offered strictly for laboratory and research use.
