Melanotan II reconstitution calculator
Reconstitution calculator for Melanotan II, prefilled for its 10 and 20 mg vials. Get the concentration, the dose volume and the U-100 syringe reading.
Start from a compound
Fills the vial size and a starting water volume. Only compounds with a citable range fill a dose.
The second is the question asked once the syringe is already filled, or when checking a vial someone else reconstituted.
1 mg = 1,000 mcg. Published figures are usually micrograms; vial labels are milligrams.

Melanotan II — Limited human data
From human studies that are small, early-phase, or for a different indication than the one this range is usually cited for. The prefilled dose is the low end of that range, daily, escalated over roughly six weeks.
Vial size and water volume are a starting point for the arithmetic, not a recommendation.
Adding more water makes the same dose a larger, easier-to-read mark on the syringe. It does not change how many doses the vial holds.
Vial sizes and starting volume
Melanotan II is commonly supplied in 10 mg and 20 mg vials. The calculator opens on a 10 mg vial with 2 mL of bacteriostatic water — a starting point for the arithmetic, not a recommendation. Change either and everything recalculates.
That combination gives 5 mg/mL, so one insulin unit holds 50 mcg and a 100 mcg dose is 2 units.
What dose to enter
A range of 100–1000 mcg per dose can be cited for Melanotan II, daily, escalated over roughly six weeks. The dose field opens at the low end of it.
Limited human data
From human studies that are small, early-phase, or for a different indication than the one this range is usually cited for.
