Calculate how much reconstituted peptide to draw for your desired dose. Enter your vial size, bacteriostatic water volume, and target dose — the numbers update as you type.
Step 1:Enter the total amount of peptide in your vial (usually printed on the label, e.g. 5 mg).
Step 2:Enter how much bacteriostatic water you added to reconstitute (a common amount is 2 mL).
Step 3:Enter your desired dose per injection (e.g. 250 mcg for BPC-157 or 0.25 mg for semaglutide).
Step 4:Select your syringe size. Most insulin syringes are 1 mL / 100 unit.
The calculator tells you exactly how many units (tick marks) to draw, the volume in mL, and how many total doses you'll get from the vial.
Working out how much bacteriostatic water to add in the first place, or how long a vial will last on your schedule? Use the reconstitution calculator, which adds protocol presets and a days-supply estimate.
Our mission is to make peptide research clear, credible, and usable for people who refuse to rely on hype.
