Peptide calculator

Reconstitute a vial, convert IU to mg, and work out pen clicks from a cartridge. Maths only. Not medical advice.

Preset

Vial contentsBacteriostatic watermLDose you want to drawSyringe

Concentration: 2.5 mg/mL (2,500 mcg/mL)
Draw: 0.1 mL · 10 units on U-100
Doses in vial: 20

1. Add water to the vial

2. Draw the dose

Wipe and inject water into the powder vial, aimed at the glass wall.
Swirl until clear. Do not shake.
Draw to the unit mark on a U-100 insulin syringe. 10 units = 0.1 mL.

Insulin syringes here are U-100: 100 units = 1 mL. Pen click size is product-specific, not universal. Swirl to dissolve, do not shake. IU/mg factors vary by manufacturer. The number printed on the vial, cartridge, or pen wins. This tool does not recommend doses, products, or medical use.
