Test Results
The label says 15 mg. Janoshik weighed 15.1 mg. Your dose depends on what is really in the vial, so the steps below use the measured amount.
Draw
20 units
on a U-100 insulin syringe, for 1.5 mg
- The vial holds dry powder: 15.1 mg of Retatrutide, as weighed.
- Water spreads that powder evenly through the liquid: 15.1 mg ÷ 2 ml = 7.54 mg per ml.
- An insulin syringe counts in units, 100 to the ml, so each unit carries 75 mcg.
- Your dose divided by that: 1.5 mg ÷ 75 mcg = 20 units.
The water changes how many units a dose takes, never how much peptide you get. Twice the water means twice the units for the same dose. What sets the dose is how much is in the vial — which is why the measured amount matters.
Arithmetic, not medical advice. Assumes a U-100 syringe and that the powder fully dissolves. The figure is from the vial that was tested; yours is from the same lot but was not weighed itself.
