Reconstitution Calculator

Calculate your exact dose, syringe units, and mixing ratios

Enter your vial size (mL), peptide amount (mg), BAC water volume, and your desired dose. The calculator will show exactly how many units to draw on your syringe.

Quick Reference

1 mL = 100 units on a U-100 syringe

1 mg = 1,000 mcg (micrograms)

Always use bacteriostatic (BAC) water for reconstitution

Store reconstituted peptides in the refrigerator

GuideHow to Use This Calculator

1

Enter Vial Size & Amount

Select your vial size in mL (3, 5, or 10 mL are standard), then enter the peptide amount in mg from your vial label.

2

Add BAC Water

Decide how much bacteriostatic water to add. More water = lower concentration = easier to measure small doses.

3

Set Your Dose

Enter the dose amount per injection in mcg, mg, or IU depending on the peptide.

4

Read Your Units

The calculator shows the exact number of units to draw on your insulin syringe. The visual shows you where the liquid line should be.
