# Mix your vial. Draw the exact units.

Units measure liquid, not medicine.

**1** of 3 · Your vial

## Your vial

Draw to Example numbers

**40** units

0.40 mL · 2 mg = 2,000 mcg

This is arithmetic, not medical advice. Your prescriber or pharmacist sets your dose and shows you how to measure it.

Example numbers

Example numbers

**5 mg in every mL** (10 mg in 2 mL)

Color shows how strong the mix is (real peptide water is clear).

All three are U-100. A U-40 syringe reads differently.

Your dose holds; the units follow the mix.
