Peptide mg to Insulin Units: Conversion Charts

The base rule

A U-100 syringe holds 1 mL at 100 units. Units = (target mg ÷ concentration mg/mL) × 100.

Choosing a diluent volume

Pick the volume that lands your target amount between 10 and 50 units — that range is where a U-100 syringe is most accurate.

How PX1 documents every lot
