IG1-0519 — Uther Receptor Grade IGF-1 LR3

The label says 1 mg. Janoshik weighed 1.05 mg — 5% more than the label. Your dose depends on what is really in the vial, so the steps below use the measured amount.

Going by the label you would draw 20 units — which from this vial is actually 105 mcg, not 100 mcg.

1. The vial holds dry powder: 1.05 mg of Receptor Grade IGF-1 LR3, as weighed.
2. Water spreads that powder evenly through the liquid: 1.05 mg ÷ 2 ml = 525 mcg per ml.
3. An insulin syringe counts in units, 100 to the ml, so each unit carries 5.25 mcg.
4. Your dose divided by that: 100 mcg ÷ 5.25 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.
