Melanotan 2 Reconstitution Calculator

Melanotan 2 is a synthetic melanocortin analog (MT-2). This page shows how to reconstitute it and read the result on a syringe — the calculator does the arithmetic for you.

Status: Not approved for human use; sold as a research compound.

The math

Concentration = vial ÷ water  ·  Units = (dose ÷ concentration) × 100

Melanotan 2 is reconstituted with bacteriostatic water; the per-unit math is the same as other small-dose peptides.

Worked example

Illustrative numbers only — not a dose recommendation.

How to use the calculator

  1. Open the calculator and enter your Melanotan 2 vial size.
  2. Enter your bacteriostatic water volume, then your dose.
  3. Read off the units to draw and doses per vial.

Frequently asked questions

How do I reconstitute Melanotan 2?
Add bacteriostatic water to the lyophilized vial to reach a concentration you can measure. For example, 10 mg in 2 mL of water gives 5 mg/mL, so each 10 units (0.1 mL) on a U-100 syringe contains about 500 mcg of Melanotan 2. Swirl gently rather than shaking.
How many units of Melanotan 2 do I draw?
Divide your intended dose by the concentration to get the volume in mL, then multiply by 100 for a U-100 syringe. The calculator does this automatically once you enter your vial size, water volume and dose.
What vial sizes does Melanotan 2 come in?
Melanotan 2 is commonly supplied as 10 mg. The amount in the vial does not change with how much water you add — water only sets the concentration.
Is Melanotan 2 approved for human use?
Not approved for human use; sold as a research compound. This calculator only performs arithmetic on the numbers you enter and does not recommend any dose.
