Test Results
Result
Heavy metals screening (As, Cd, Pb, Hg) - as add-on to another test — As: not detected. Cd: not detected. Pb: not detected. Hg: not detected.
The label says 20 mg. Janoshik weighed 25.3 mg — 26% more than the label. Your dose depends on what is really in the vial, so the steps below use the measured amount.
Draw
16 units
on a U-100 insulin syringe, for 2 mg
Going by the label you would draw 20 units — which from this vial is actually 2.53 mg, not 2 mg.
- The vial holds dry powder: 25.3 mg of Retatrutide, as weighed.
- Water spreads that powder evenly through the liquid: 25.3 mg ÷ 2 ml = 12.6 mg per ml.
- An insulin syringe counts in units, 100 to the ml, so each unit carries 126 mcg.
- Your dose divided by that: 2 mg ÷ 126 mcg = 16 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.
