Peptide Reconstitution Calculator
Punch in your vial size and how much bacteriostatic water you’ll add, get back your draw volume in milliliters and units. Or flip it: tell us your target units and we’ll calculate the BAC water to use.
Total milligrams of peptide inside the vial.

Volume of bacteriostatic water you mix into the vial.

Common
A standard vial will not hold more than 3 ml of bacteriostatic water.
How much peptide each dose should deliver.
mg per dose
Common
Draw this much per dose
On a U-100 insulin syringe
25 units
= 0.250 ml drawn
Vial concentration
5.00 mg/ml
≈ 40 doses per vial
Draw exceeds 100 units, won’t fit on a single U-100 syringe.

e.g. “I want each dose to read as 20 units”, we’ll figure out how much BAC water to add to get there.

Mix the vial like this
Add this much BAC water

A standard vial will not hold more than 3 ml of bacteriostatic water. Lower your target units or use a larger-capacity vial.
