Melanotan II dosage calculator
Calculate your Melanotan II reconstitution volume, dose per injection, and how long your supply will last. Enter your vial size and target dose below.
Reconstituting a 10 mg vial of Melanotan II with 2 mL of bacteriostatic water gives a concentration of 5000 mcg/mL. At that concentration a 250 mcg dose is 0.050 mL, which is 5.0 units on a U-100 insulin syringe, and one vial yields 40 doses of that size. Change the vial size, water volume or target dose and the arithmetic changes — the table below covers the common doses, and the calculator handles any combination.

Common doses at a glance.
Every row assumes a 10 mg vial reconstituted with 2 mL of bacteriostatic water, drawn on a U-100 syringe.
| Dose | Volume | Draw to | Doses per vial |
|---|---|---|---|
| 100 mcg | 0.020 mL | 2.0 U | 100 |
| 250 mcg | 0.050 mL | 5.0 U | 40 |
| 500 mcg | 0.100 mL | 10.0 U | 20 |
How the arithmetic works.
- conc = 10 mg ÷ 2 mL = 5000 mcg/mL
- vol = 250mcg ÷ 5000 = 0.050 mL
- units = 0.050 mL × 100 = 5.0 U
A U-100 syringe is graduated so that 100 units equals 1 mL, which is why the volume in millilitres is multiplied by 100 to get the mark to draw to.
This tool does unit arithmetic and nothing else. It does not know your body weight, bloodwork, medication interactions or tolerance, and it does not recommend a dose — the dose you enter is the dose you chose. It assumes a U-100 syringe and full dissolution of the compound, and it cannot account for measurement error, product purity, or a vial that was under-filled.
