Melanotan II Units Chart (5 mg vial)
Worked example
Worked example: a 5 mg vial of Melanotan II with 2 mL of water has a concentration of 2.5 mg/mL, so a 250 mcg example amount reads 10 units and 500 mcg reads 20 units on a U-100 syringe. With 5 mL the same 250 mcg reads 25 units.

|---|---|---|---|---|---|---|---|---|---|---|---|
| 50 | 100 | 250 | 500 | 750 | 1000 | 1500 | 2000 | 2500 | 5000 | ||

How it works
Each cell is units = target amount in mg / concentration x 100, where concentration = vial mass / water volume. For 5 mg in 2 mL the concentration is 2.5 mg/mL, so a 250 mcg example amount is 0.25 / 2.5 x 100 = 10 units.
Frequently asked questions
What does a 250 mcg example amount of Melanotan II read on a U-100 syringe for a 5 mg vial?
It depends on the water volume: 5 units with 1 mL, 10 with 2 mL, 15 with 3 mL and 25 with 5 mL in a 5 mg vial.
Why do the chart rows differ for the same 5 mg of Melanotan II?
More water lowers the concentration, from 5 mg/mL at 1 mL to 1 mg/mL at 5 mL, so the same target amount occupies more volume and reads more units.
How many mcg of Melanotan II does one syringe unit hold in this vial?
One unit is 0.01 mL. At 2.5 mg/mL (the 2 mL row) one unit holds 25 mcg of Melanotan II.
