Test Results
The label says 50 mg. Janoshik weighed 53.5 mg — 7% more than the label. Your dose depends on what is really in the vial, so the steps below use the measured amount.
Draw
19 units
on a U-100 insulin syringe, for 5 mg
Going by the label you would draw 20 units — which from this vial is actually 5.35 mg, not 5 mg.
- The vial holds dry powder: 53.5 mg of Retatrutide, as weighed.
- Water spreads that powder evenly through the liquid: 53.5 mg ÷ 2 ml = 26.8 mg per ml.
- An insulin syringe counts in units, 100 to the ml, so each unit carries 268 mcg.
- Your dose divided by that: 5 mg ÷ 268 mcg = 19 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.
