- Researchers selecting melanocortin peptides face a choice between Melanotan-1, Melanotan-2, and pharmaceutical afamelanotide (Scenesse). Each offers distinct pharmacological profiles and research applications. The table below compares receptor selectivity, half-life, typical research dosing, and primary study applications.
- Melanotan-1
- 100–1000× selective for MC1R over MC3R/MC4R
- 2.5–3.5 hours subcutaneous
- 0.5–2.0 mg/dose
- Isolated melanogenesis studies, photoprotection mechanisms, MC1R binding assays
- Best choice for studies requiring minimal confounding from appetite or metabolic effects—receptor selectivity allows attribution of effects specifically to MC1R pathway
- Melanotan-2
- 10–20× selective for MC1R; significant MC3R/MC4R activity
- 1.5–2.5 hours subcutaneous
- 0.25–1.0 mg/dose
- Multi-receptor melanocortin studies, appetite/energy regulation, combined metabolic-pigmentation research
- Appropriate when simultaneous melanocortin pathway activation is desired, but introduces confounding variables if isolating MC1R effects is the goal
- Afamelanotide (Scenesse)
- Identical to Melanotan-1
- 2.0–3.0 hours; extended via implant formulation
- 16 mg implant (releases over 60 days)
- Clinical photoprotection studies, erythropoietic protoporphyria research
- Pharmaceutical-grade standardization with regulatory approval, but implant delivery system limits dose flexibility for controlled experiments
- Melanotan-1 demonstrates the highest MC1R selectivity in competitive binding assays, making it the preferred choice when research protocols require isolation of MC1R-mediated effects from the broader melanocortin system. The distinction matters most in controlled mechanistic studies where appetite suppression or erectile function changes would confound interpretation of melanogenesis data.
