Melanotan‑1 (Afamelanotide)
α-MSH analog, approved for erythropoietic protoporphyria
WHAT IS MELANOTAN-1 (AFAMELANOTIDE)?
Detailed overview
Afamelanotide (Scenesse) is an α-MSH analog that drives melanogenesis via MC1R. FDA-approved in 2019 for EPP to reduce phototoxic reactions. Available in two forms: subcutaneous injection (FDA-approved Scenesse implant + research protocol) and intranasal spray (Hadley-style research route, lower efficacy).

Skin / sexual health
Melanocortin (MC1R / MC4R) receptor activation produces two main effects: skin pigmentation (melanin synthesis, UV protection, cosmetic) and centrally-mediated libido / sexual response. The peptide also supports collagen I/III and elastin synthesis, improving skin elasticity and texture, youth markers measurably rise. Acute effect (libido, energy) often within 30–60 min; lasting effects (tone, pigmentation) build over 1–3 weeks. Routine mole checks recommended.

Research indications
Investigated uses and mechanisms
Libido & sexual function
Central (MC4R) pathway activation; libido and function improve.
Skin pigmentation
Increased melanin synthesis (UV-protection, cosmetic aim).
Collagen / skin elasticity
Rises in youth markers (collagen I, III).
Reconstitution
How to prepare, step by step
Important
Sterile technique required. Use bacteriostatic water (BAC) only. Never distilled or tap water.
- 01
10 mg lyophilized vial + 5 ml bacteriostatic water
- 02
Inject water slowly onto vial wall, NOT directly onto powder
- 03
Wait 30 seconds, swirl gently (DO NOT shake)
- 04
Storage: refrigerated (2–8°C), max 28 days
