Quick math example
A 10 mg vial mixed with 2 mL gives 5 mg/mL, or 5,000 mcg/mL. A 250 mcg dose is 0.05 mL, which equals 5 units on a U-100 syringe.
How the Melanotan II calculation works
Melanotan II is labelled in milligrams per vial. Concentration is total mg divided by BAC water volume; the per-dose volume is your target divided by that concentration.
Starting protocols are usually small (around 250 mcg) and increased gradually, so per-dose draws are small and benefit from a U-100 insulin syringe for readability.
- 10 mg vial = 10,000 mcg total
- 10,000 mcg / 2 mL = 5,000 mcg per mL
- 250 mcg target = 0.05 mL draw
Regulatory and safety context
Melanotan II is unapproved in most major markets and has been associated with skin lesions and other adverse effects in published reports. This page only covers the calculator math; the decision to use it sits outside the scope of this tool.
Frequently asked questions
Is Melanotan II approved as a medicine?+
Melanotan II is not approved as a medicine in most major markets. This page only explains calculator math and does not make treatment recommendations.
Why are starting Melanotan II doses so small?+
Community protocols typically start small to gauge tolerability before increasing. The calculator returns whatever draw matches your entered target, so smaller targets give smaller draws.
Can I stack Melanotan II with other peptides?+
The calculator handles each compound's math independently. Stacking is a protocol decision; this page does not provide guidance on combining compounds.
