A range exists, but the evidence is preliminary
The range above is what studies or protocols have used, but no human trial has established that Melanotan II is effective at it. Converting a dose does not make the dose validated. See the graded evidence on the Melanotan II profile before relying on any figure here.

Concentration by vial and diluent
| Vial | 1 mL diluent | 2 mL diluent | 3 mL diluent |
|---|---|---|---|
| 2 mg | 2,000 mcg/mL | 1,000 mcg/mL | 667 mcg/mL |
| 5 mg | 5,000 mcg/mL | 2,500 mcg/mL | 1,667 mcg/mL |
| 10 mg | 10,000 mcg/mL | 5,000 mcg/mL | 3,333 mcg/mL |
Concentration is vial mass divided by diluent volume. Reconstitution volume changes what you draw, never the dose itself.
