Reconstitution simulator

Practice the math before you ever touch a vial. Pick a vial, add bacteriostatic water, enter an amount, and watch the syringe fill to the matching line on a U-100 insulin syringe. This is arithmetic practice, not a dose recommendation.

–units

Add water to mix the vial.

Start from a compound (optional)

1Pick the vial

2Add bacteriostatic water

0 mL

On an insulin syringe, 100 units = 1 mL.

Inject the water slowly down the inside wall, then swirl gently until clear. Never shake. Most 2–10 mg vials take 1–3 mL; you use only part of a 30 mL bottle of bacteriostatic water.

3Enter the amount to draw

4Syringe size

Same math as the calculator and vial sizes. Learn the steps in the reconstitution guide and syringes and units.

Practice only. Nothing here is a recommendation to use any compound. Doses offered under “Start from a compound” are the ones on record for it, with their source shown on its flashcard and profile.
