Melanotan 1
Also known as: MT-1 · Afamelanotide · CUV1647
A synthetic analog of alpha-MSH that stimulates melanin production for skin tanning. The more selective of the two Melanotan variants, with FDA-orphan drug status for erythropoietic protoporphyria.
Mechanism of Action
Melanotan 1 selectively activates MC1R on melanocytes, stimulating melanin production without activating sexual arousal pathways.
Benefits
- Promotes skin tanning without UV exposure
- FDA-approved form for erythropoietic protoporphyria
- Reduces UV-induced skin damage
- More selective than Melanotan 2
- Lower sexual arousal side effects
Side Effects & Risks
- Nausea
- Flushing
- Fatigue
- Mild libido changes
- Injection site reactions
- Possible new moles
