Calculate your exact Melanotan II dose
Pre-filled with Melanotan II’s commonly cited vial and dose. Change any field to match your vial — it shows the exact units, concentration, and doses per vial.
Add 2 mL of bacteriostatic water to your 10 mg vial. That gives you about 40 doses of 250 mcg. For each dose, draw 5 units into a 100-unit insulin syringe.
Melanotan II dosing FAQ
How many units of Melanotan II should I draw?
Reconstituting a 10 mg vial of Melanotan II with 2 mL of bacteriostatic water gives 5 mg/mL. A 250 mcg dose is about 5 units on a U-100 insulin syringe, roughly 40 doses per vial. This is a commonly cited example for context, not medical advice.
How much bacteriostatic water do I add to Melanotan II?
There is no single correct amount. More water makes each dose a larger, easier-to-measure volume; less water makes it more concentrated. The chart above shows the units for 1–5 mL — 2 mL is a common choice for a 10 mg vial.
How many doses are in a 10 mg Melanotan II vial?
At a 250 mcg dose, a 10 mg vial holds about 40 doses. Larger doses mean fewer doses per vial, and the amount of water you add does not change this.
