Melanotan II Reconstitution & Dosing
Also known as: MT2, MT-2
Quick answer: mix a 10 mg vial of Melanotan II with 2 ml of bacteriostatic water. That gives 5.00 mg/ml, so a typical 250 mcg dose is 5.0 units on a U-100 insulin syringe — about 40 doses per vial. Reported protocols range 100 mcg–500 mcg, daily during loading, then 1–2x weekly.
Melanotan II is a melanocortin agonist that stimulates melanin production for tanning with minimal UV exposure. Protocols start very low (100 mcg) to gauge nausea and flushing response before scaling. Full overview: what is Melanotan II? →
⚠ Start-low matters: side effects (nausea, flushing) are dose-dependent and front-loaded.
