BPC-157 peptide calculator
Pre-filled BPC-157 dosage and reconstitution math: a 5 mg vial, 2 ml of bacteriostatic water, and the resulting U-100 insulin-syringe units. Adjust the inputs below or open the full calculator.
How to reconstitute BPC-157
- Wipe both vial stoppers with a fresh alcohol swab and let them dry.
- Draw 2 ml of bacteriostatic water into a syringe.
- Insert the needle at an angle into the BPC-157 vial and let the water run slowly down the inner wall — do not inject directly onto the powder.
- Do not shake. Gently swirl the vial until the peptide fully dissolves.
- Store the reconstituted vial refrigerated (2–8 °C / 36–46 °F) and use within roughly 28 days.
- Draw each dose to the unit mark shown above for your target 250 mcg dose.
About BPC-157
BPC-157 is a synthetic pentadecapeptide fragment of body protection compound found naturally in gastric juice. It is studied for its effects on tendon, ligament, muscle, and gastrointestinal tissue repair.
Half-life: Oral form ~4 hours; subcutaneous estimated 4–6 hours
Typical dose range: 200–500 mcg per injection, 1–2x daily
Class: Gastric pentadecapeptide (15 amino acids)
BPC-157 calculator FAQ
Is this a BPC-157 peptide calculator or a reconstitution calculator?
Both. This BPC-157 calculator converts vial strength, bacteriostatic-water volume, and target dose into milliliters and insulin-syringe units. It does not recommend a medical dose.
How much bacteriostatic water for a 5 mg BPC-157 vial?
This page is pre-filled with 2 ml of bacteriostatic water for a 5 mg BPC-157 vial because that is a common research ratio. You can adjust the water amount in the full calculator.
How many units is a 250 mcg BPC-157 dose?
With the default 5 mg vial and 2 ml BAC-water ratio, the preview above calculates the U-100 syringe units for a 250 mcg dose. Change the dose if your protocol uses a different amount.
Does this BPC-157 dosage calculator give medical advice?
No. It only performs unit math. Dosing, titration, and whether BPC-157 is appropriate are clinical decisions that should be made with a licensed healthcare professional.
