Reconstitution Calculator

Dose calculator for research peptides

Enter your vial size, the volume of bacteriostatic water you mixed it with, and your target dose. We'll tell you exactly how many units to draw on a standard insulin syringe.

Peptide (optional)

Vial size (mg)

BAC water (ml)

Target dose (mcg)

Tip: 1 mg = 1,000 mcg. A 250 mcg dose = 0.25 mg.

units on a U-100 (1 ml insulin) syringe

Volume per dose0.100 ml

Concentration2,500 mcg/ml

Doses per vial~20.0

How the math works: Vial size (mg) × 1,000 = total mcg in the vial. Divide by ml of BAC water to get the concentration (mcg/ml). Your target dose (mcg) ÷ concentration = ml to draw. Multiply by 100 for units on a U-100 insulin syringe.
