Retatrutide Units Chart (60 mg vial)
Worked example
For 60 mg of Retatrutide, the chart row for 2 mL shows 30 mg/mL: 250 mcg is 0.8333 units and 500 mcg is 1.6667 units. The 5 mL row drops the concentration to 12 mg/mL and moves 250 mcg to 2.0833 units.

How it works
Each cell is units = target amount in mg / concentration x 100, where concentration = vial mass / water volume. For 60 mg in 2 mL the concentration is 30 mg/mL, so a 250 mcg example amount is 0.25 / 30 x 100 = 0.8333 units.
Frequently asked questions
How many units is 250 mcg of Retatrutide from a 60 mg vial?
It depends on the water volume: 0.4167 units with 1 mL, 0.8333 with 2 mL, 1.25 with 3 mL and 2.0833 with 5 mL in a 60 mg vial.
Why does adding more water change the unit reading?
More water lowers the concentration, from 60 mg/mL at 1 mL to 12 mg/mL at 5 mL, so the same target amount occupies more volume and reads more units.
How much Retatrutide is in one unit on a U-100 syringe?
One unit is 0.01 mL. At 30 mg/mL (the 2 mL row) one unit holds 300 mcg of Retatrutide.
