- Melanotan-1 (Afamelanotide)
- MC1R, MC5R
- 30–40 minutes
- Erythropoietic protoporphyria, vitiligo, photoprotection, DNA repair studies, neuroprotection
- FDA approved (EPP), EMA approved
- Gold standard for UV-independent melanogenesis research. Receptor selectivity eliminates metabolic confounders
- Melanotan-2
- MC1R, MC3R, MC4R, MC5R
- 60–90 minutes
- Erectile dysfunction models, appetite research, metabolic studies
- No regulatory approval (research-only)
- Broader receptor activity useful for multi-system studies but introduces off-target variables in isolated pigmentation research
- Alpha-MSH (endogenous)
- 5–7 minutes
- Baseline melanocortin signaling reference, physiological control
- N/A (endogenous hormone)
- Extremely short half-life limits practical use in controlled protocols. Rapid enzymatic degradation by neprilysin
- NDP-α-MSH (synthetic analog)
- 15–20 minutes
- Broad melanocortin research, receptor binding assays
- Research-only (no clinical approval)
- Longer half-life than natural α-MSH but still shorter than melanotan-1. Useful for acute signaling studies
- Melanotan-1's combination of MC1R selectivity, sustained half-life, and FDA-approved clinical data makes it the most reproducible choice for photoprotection and pigmentation research. Broader-spectrum agonists like melanotan-2 are better suited for metabolic or multi-receptor studies but introduce variables that complicate interpretation in dermatological models.
