Melanotan 2 dosage calculator
A reconstitution calculator preloaded with an example Melanotan II vial size. Enter your own vial mass, diluent, and dose to get concentration, draw volume, and insulin-syringe units. Arithmetic only - it does not tell you what dose to use.

Your vial
Printed on the vial. There is no standard size - enter what yours says.
This changes how much you draw - never how many doses the vial holds.
100 units per mL. 1 unit = 0.01 mL. This is what almost every insulin syringe sold is, in every barrel size.
Capacity only. A 1 mL U-100 syringe holds 100 units - the scale decides that, not the barrel.

What Melanotan 2 dosing actually looks like
Melanotan II has no approved product, so there is no approved dose. The common protocol reported by dosing-guide and community sources is a daily loading dose of 100-1000 mcg by subcutaneous injection for 4-8 weeks, then 250-1000 mcg 1-3 times a week to maintain it - common practice, not trial-established. The published human dosing data come from three small studies in 23 men: a 1996 pilot in 3 men at 0.01-0.03 mg/kg on alternate days over two weeks, and two erectile dysfunction trials at 0.025 mg/kg. A 2012 case report of a man who injected 6 mg at once shows what happens far above those amounts: rhabdomyolysis and an ICU stay. None of these figures is a recommendation. Read the full breakdown on theMelanotan 2 dosage page, and the overdose case on theMelanotan 2 overdose page.
Common questions
What is a typical Melanotan 2 vial size?
Research-sold Melanotan II is commonly listed in 10 mg vials. This calculator preloads 10 mg as an example vial size only - it is not a recommendation, and it does nothing to verify what is actually in any vial you own.
What dose does the calculator start with, and why?
It starts at 250 mcg, which sits within the 100-1000 mcg daily loading range dosing-guide and community sources describe - common practice, not trial-established, and not a recommendation. With the preset 10 mg vial and 2 mL of water (5,000 mcg per mL), 250 mcg is 0.05 mL, or 5 units on a U-100 syringe. It is far below the 6 mg single injection linked to rhabdomyolysis and an ICU stay in a published case report - see the Melanotan 2 dosage page for what the three small published human studies actually used.
What is the common Melanotan 2 dose?
Dosing-guide and community sources describe a daily loading dose of 100-1000 mcg by subcutaneous injection for 4-8 weeks to build pigmentation, then 250-1000 mcg taken 1-3 times a week to maintain it, followed by a break of roughly 4-6 weeks. That is common practice, not trial-established: no regulator or published study has set it as safe or effective.
Is there an FDA-approved Melanotan 2 dose?
No. Melanotan II has no FDA-approved product and no dose established as safe or effective by any regulator. It was also nominated to, then withdrawn from, FDA review for compounding. The calculator performs arithmetic on numbers you enter; it does not know what dose is appropriate.
Is a melanotan 2 dosage calculator different from a mixing or reconstitution calculator?
No - dosage, dosing, mixing and reconstitution calculators for Melanotan 2 are the same arithmetic under different search names: concentration after mixing, draw volume for a dose, and syringe units.
What does an overdose look like?
A published case report describes a man who injected 6 mg at once - self-reported as six times his own usual starting dose - and developed sympathomimetic toxicity and rhabdomyolysis requiring three days of ICU care. See the Melanotan 2 overdose page for the full case and warning signs.
Where can I read what the Melanotan 2 study actually used?
The Melanotan 2 dosage page covers the three small published human studies, 23 men in all - the 1996 Phase I pilot in 3 men (escalating from 0.01 to 0.025-0.03 mg/kg subcutaneously, given on alternate days, about 5 doses over two weeks) and two erectile dysfunction trials of 10 men each at 0.025 mg/kg - plus the 2012 overdose case report, each attributed to its source.
