Melanotan is a synthetic analog of the naturally occurring peptide hormone α-MSH (alpha-melanocyte-stimulating hormone).
It works by binding to melanocortin receptors (primarily MC1R), which regulate skin pigmentation. Melanotan has been studied for its ability to stimulate melanin production, providing a tanning effect and potential protection against UV damage. There are two common forms: Melanotan I (afamelanotide), which has undergone clinical testing for rare skin disorders, and Melanotan II, which has been investigated for tanning, libido, and metabolic effects. Neither form is FDA-approved for cosmetic tanning or general therapeutic use.
How It Is Used in Research Settings
- Studied for stimulating melanin production in skin pigmentation research.
- Explored as a protective agent against UV radiation and skin damage.
- Investigated for potential sexual function effects via melanocortin receptor activity (Melanotan II).
- Examined in appetite and metabolic studies due to melanocortin pathway involvement.
Proposed Uses (Research Areas)
- Skin pigmentation and photoprotection studies.
- UV radiation damage prevention research.
- Sexual function and libido research (Melanotan II).
- Metabolic health and appetite regulation models.
How It Is Dosed in Research Settings
- Injectable (Subcutaneous): Research dosing ranges widely — often starting at 250–500 mcg and titrated upwards depending on pigmentation response.
- Maintenance: Some studies use 500 mcg–1 mg two to three times per week after initial pigmentation is achieved.
- Cycle length: Varies from several weeks (for tanning studies) to ongoing intermittent use in pigmentation research.
- Handling: Supplied as lyophilized powder; reconstituted with bacteriostatic water and stored refrigerated.
Important Considerations
- Regulatory status: Melanotan I (afamelanotide) has undergone clinical testing for rare conditions like erythropoietic protoporphyria (EPP).
Melanotan II is not approved for medical use. Neither is FDA-approved for tanning or cosmetic purposes. - Evidence base: Research shows reliable increases in melanin production, but long-term effects and safety require more study.
- Safety: Reported research side effects include nausea, flushing, darkening of moles/freckles, reduced appetite, and spontaneous erections (Melanotan II).
The long-term risks, including potential links to melanoma, remain uncertain.
