How to Use This Calculator

  1. Select the vial size — the total milligrams of peptide printed on your vial label.
  2. Choose your water volume — how many mL of bacteriostatic water you'll inject into the vial to reconstitute the peptide.
  3. Enter your desired dose — type the number and pick your preferred unit (mcg, mg, or syringe units). Results update automatically.
  4. Read your results — the calculator shows concentration, all dose equivalents, and how many injections are in the vial.

Your Vial Details

For your own reference — appears on the printed summary. Does not affect calculations.

Total milligrams of peptide in the vial, as stated on the label. This is not your dose — it is the entire contents of the vial.

The volume of bacteriostatic water (BW) you will inject into the vial. More water dilutes the peptide further, lowering the concentration per mL and increasing the volume per dose. Most users choose 1–2 mL for convenient dosing with a standard insulin syringe.

Your Desired Dose

Required

Type your dose in whichever unit you prefer. mcg (micrograms) is most common for peptides. Syringe units are the tick marks on a standard U-100 insulin syringe (100 units = 1 mL).
