RE100806 — Uther Retatrutide

Going by the label you would draw 20 units — which from this vial is actually 1.22 mg, not 1 mg.

1. The vial holds dry powder: 12.2 mg of Retatrutide, as weighed.
2. Water spreads that powder evenly through the liquid: 12.2 mg ÷ 2 ml = 6.1 mg per ml.
3. An insulin syringe counts in units, 100 to the ml, so each unit carries 61 mcg.
4. Your dose divided by that: 1 mg ÷ 61 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.
