Melanotan II
How to reconstitute the 10 mg vial and convert any target dose into insulin units. Reconstitution math and unit conversions for the 10 mg vial. Melanotan II is an unapproved research chemical regulators have warned against; it has no validated human dose and the figures shown are community-reported.
No validated human dose. Melanotan II is a research-use peptide with no FDA-approved dose. The reconstitution math below is exact measurement — a calculator, not advice. Any usage figures are community-reported and clearly labeled, and none of this is medical advice.
Calculate for your vial
Enter the mg on your Melanotan II vial, the bacteriostatic water you added, and your target dose — it works out the exact units to draw on a U-100 insulin syringe, for whatever you personally have.

Check the decimal. A misplaced decimal point here is a 10× dosing error. Re-read every number, and confirm your dose with a licensed clinician before you draw.
Educational only — not a dosing recommendation. This tool does the measurement math; it does not tell you what to take. On a U-100 insulin syringe, 100 units = 1 mL.
1 · Find your dose
Pick what you're using Melanotan II for and how much bacteriostatic water you added — this pulls out the exact units to draw and how often people report using it.

Community-reported and anecdotal (~100–500 mcg per subcutaneous injection). Melanotan II is not FDA-approved; the FDA and other agencies have warned against unapproved melanotan products, citing nausea, blood-pressure changes, and darkening/changes of moles. No validated human dose exists — this is not a recommendation.
2 · Reconstitute it cleanly, step by step
How to turn the 10 mg powder into a measured liquid with clean, sterile technique. More water means each insulin unit holds less peptide — easier to measure small amounts accurately.
1Swab the stoppers
Wipe the rubber top of each vial with an alcohol pad and let it air-dry.
2Draw the water
Pull your bacteriostatic water up into the insulin syringe.
3Reconstitute
Inject it slowly down the inside wall of the peptide vial — never straight onto the powder.
4Swirl to dissolve
Gently swirl until the powder fully dissolves into a clear liquid. Never shake.
5Equalize, then draw
To draw a dose: push in an equal amount of air first to equalize the pressure, then pull your dose.

Swab both tops
Wipe the rubber top of the bacteriostatic-water vial and the Melanotan II vial stopper with a fresh alcohol pad, and let them air-dry. Never touch the needle or the stoppers after wiping.

Draw the water
First pull 2 mL of air into the syringe and inject it into the bacteriostatic-water vial to equalize the pressure, then draw your 2 mL of water back out. Inject it into the Melanotan II vial down the inside glass wall, not onto the powder.

Swirl, don't shake
Gently swirl the 10 mg vial until the powder fully dissolves into a clear liquid. Never shake — shaking can damage the peptide and foam the solution.

Know your strength
The vial is now 5 mg/mL. Each unit on a U-100 syringe holds about 50 mcg.
5 mg/mL - 5
Re-swab & draw your dose
Wipe the stopper again. With a fresh insulin syringe, pull back 5 units of air and inject it into the vial to equalize the pressure, then draw 5 units (0.05 mL) for a 250 mcg dose.
5 units - 6
Store it right
Keep the mixed vial in the fridge, away from light. Use a new sterile syringe every time, never share, and drop used sharps in a proper container.

4 · Everyday usage
Melanotan II is a research chemical that regulators have warned against. It has no validated human dose; the pattern below is community-reported, and these compounds are known for dose-dependent nausea and skin/mole changes.

Frequently asked questions
How many insulin units is 100 mcg of Melanotan II from a 10 mg vial?
- Reconstituting a 10 mg vial with 2 mL of bacteriostatic water gives 5 mg/mL — about 50 mcg per unit. Drawing 100 mcg is 0.02 mL, or 2 units on a U-100 insulin syringe. This is measurement math, not a dose recommendation.
How many insulin units is 250 mcg of Melanotan II from a 10 mg vial?
- Reconstituting a 10 mg vial with 2 mL of bacteriostatic water gives 5 mg/mL — about 50 mcg per unit. Drawing 250 mcg is 0.05 mL, or 5 units on a U-100 insulin syringe. This is measurement math, not a dose recommendation.
Is there a safe established dose of Melanotan II?
- No. Melanotan II is an unapproved research chemical that regulators have specifically warned consumers against using. There is no validated human dose; the figures here are community-reported and anecdotal, and reported effects include nausea, blood-pressure changes, and changes to moles. Decisions belong with a licensed clinician.
