Reconstitution & dosing calculator
Enter how much peptide is in the vial, how much bacteriostatic water you add, and your target dose. The calculator returns the concentration and how far to draw on an insulin syringe.
Inputs
Which do you know?
You want a set amount of compound. We show how many units to draw on the syringe.
Reminder: 1 mg = 1,000 mcg
Total amount stated on the vial, e.g. 5 mg.
How much diluent you draw into the vial.
Check this before you read the result. 1 mg = 1,000 mcg, so picking the wrong one is a 1,000x error, not a rounding error.

Draw to
10 units
= 0.1 mL on a U-100 syringe
Easy draw: this dose comes out to a clean 10 units.
Aim for a dose that lands on an even number of units, like 10, 20, or 50. It is easier to draw accurately and to remember, and it keeps you off awkward repeating decimals.
