Test Results
Dosing with this lot
The label says 15 mg. Janoshik weighed 16.8 mg — 12% more than the label. Your dose depends on what is really in the vial, so the calculator uses the measured amount.
Draw
18 units
on a U-100 insulin syringe, for 1.5 mg
Going by the label you would draw 20 units — which from this vial is actually 1.68 mg, not 1.5 mg.
- The vial holds dry powder: 16.8 mg of Tirzepatide, as weighed.
- Water spreads that powder evenly through the liquid: 16.8 mg ÷ 2 ml = 8.38 mg per ml.
- An insulin syringe counts in units, 100 to the ml, so each unit carries 84 mcg.
- Your dose divided by that: 1.5 mg ÷ 84 mcg = 18 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.
