- The table below compares three melanocortin agonist research protocols. Melanotan-2 monotherapy, PT-141 monotherapy, and Melanotan-2 + PT-141 stacked administration. Across key variables including receptor targets, adverse event profiles, dose ranges, and recommended spacing intervals.
- | Protocol | Primary Receptor Targets | Typical Dose Range | Peak Plasma Time | Common Adverse Events (Incidence) | Recommended Spacing | Bottom Line Assessment ||—|—|—|—|—|—|| Melanotan-2 Monotherapy | MC1R, MC3R, MC4R, MC5R (non-selective) | 500–1000 mcg subcutaneous | 1–2 hours | Nausea (40–60%), flushing (30–50%), hyperpigmentation (90%+), spontaneous erections (males, 20–40%) | Daily or alternate days; 24-hour minimum between doses | Best for protocols prioritizing pigmentation, appetite suppression, or broad melanocortin pathway activation; nausea limits dose escalation || PT-141 Monotherapy | MC3R, MC4R (selective; minimal MC1R) | 1.0–2.0 mg subcutaneous | 1–2 hours | Nausea (35–55%), flushing (25–45%), hypertension (15–25%), headache (10–20%) | As-needed or 2–3x weekly; 48-hour minimum between doses | Best for protocols targeting sexual arousal endpoints without pigmentation; fewer MC1R-mediated effects but similar GI/cardiovascular load || Melanotan-2 + PT-141 Stack | MC3R, MC
- Monotherapy protocols are more predictable and better tolerated in the first 2–3 weeks of research. Stacking adds complexity and requires precise dose calibration to avoid receptor competition and side effect amplification. It is not a beginner protocol.
