    About the Melanotan 2 Reconstitution Calculator

    Melanotan 2 (MT-2) is typically supplied as a 10 mg lyophilized vial. Research protocols usually start with a low loading dose (250 mcg) that steps up over several days to a target range, then a lower weekly maintenance dose.

    Enter your vial strength, bacteriostatic water volume, and dose to get the mg/mL concentration, mL to draw, and equivalent insulin units. A 10 mg vial reconstituted with 1 mL of bacteriostatic water yields 10 mg/mL — a 250 mcg dose is exactly 0.025 mL (2.5 units), and a 500 mcg dose is 0.05 mL (5 units).

    How to prepare Melanotan II

    1. Draw the intended volume of bacteriostatic water into a sterile syringe.
    2. Slowly inject the water down the inside wall of the Melanotan 2 vial — never directly onto the lyophilized powder.
    3. Gently swirl (do not shake) until the powder is fully dissolved and the solution is clear.
    4. Store the reconstituted vial refrigerated at 2–8°C and use within the peptide's stability window.
    5. Use the concentration and dose volume calculated above to draw each research dose into an insulin syringe.

    Frequently asked questions

    How do I reconstitute Melanotan 2?

    Add bacteriostatic water to the Melanotan 2 vial using the volume the calculator recommends for your desired concentration. Slowly inject the water down the side of the vial, swirl gently, and store the vial refrigerated.

    What bacteriostatic water volume should I use for Melanotan 2?

    Common choices are 1 mL, 2 mL, or 3 mL of bacteriostatic water. The right volume depends on your vial strength and target dose — use the calculator above to get a concentration that lets you draw your dose in whole insulin units.

    What is a typical research dose range for Melanotan 2?

    Reported research dose ranges for Melanotan 2 are 250–1000 mcg per dose, titrated slowly. Always verify against current literature — this tool is for research reference only, not medical advice.

    How long is Melanotan 2 stable after reconstitution?

    Once reconstituted with bacteriostatic water and stored refrigerated (2–8°C), most peptides remain stable for roughly 28–30 days. Check the specific stability data for Melanotan 2 for your batch.

    Can I use this Melanotan 2 calculator with any insulin syringe?

    Yes. The calculator supports U-100 syringes in 30, 50, and 100-unit capacities and shows both the mL dose volume and the equivalent insulin units for whichever syringe you choose.
