Melanotan II Calculator
Melanotan II (also known as MT-II) reconstitution and dosage reference — calculate vial concentration, BAC water volume, and exact syringe units below.
At the reference preset of a 10mg Melanotan II vial reconstituted with 2 mL of bacteriostatic water, a 0.5mg dose measures 10 units on a U-100 insulin syringe.
Melanotan II is a synthetic non-selective melanocortin receptor agonist studied for skin pigmentation and sexual response.

How to use this calculator›
- 1. Vial — the peptide amount printed on the vial, in milligrams.
- 2. BAC water — the bacteriostatic water added to the vial. More water means a lower concentration and a larger, easier-to-read draw.
- 3. Dose — the single dose being measured, in milligrams.
- 4. Syringe — the barrel being drawn into. The diagram rescales to that syringe, so the same dose sits at a different mark on a 0.3 mL barrel than on a U-100.

| 10 mg | lyophilized powder |
| 0.25 mg | ≈ 5 U-100 units (at 10mg / 2mL) |
| 0.5 mg | ≈ 10 U-100 units (at 10mg / 2mL) |

How it's typically prepared
Reconstitute with BAC water; refrigerate. Many users start with very low doses (e.g. 0.25 mg) and titrate slowly to assess tolerance to nausea.
Frequently asked questions
- Is Melanotan II safe?
- Several safety concerns are documented in case reports including changes in moles, nausea, and rare cases of melanoma diagnosis after use. Discuss risks with a clinician.
