BPC-157 peptide calculator
A 5 mg BPC-157 vial mixed with 2 ml of bacteriostatic water holds 2.5 mg/ml. A 250 mcg dose is 0.10 ml — 10 units on a U-100 insulin syringe — and the vial holds 20 doses of that size.
BPC-157 dosage chart: units to draw
Units on a U-100 insulin syringe (100 units = 1 ml) for BPC-157 doses from 200 mcg to 500 mcg, by how much bacteriostatic water is in a 5 mg vial. The highlighted row is the 250 mcg dose used above.
| Dose | 1 ml water 5 mg/ml | 2 ml water 2.5 mg/ml | 3 ml water 1.67 mg/ml | Doses per vial |
|---|---|---|---|---|
| 200 mcg | 4 u 0.040 ml | 8 u 0.080 ml | 12 u 0.12 ml | 25 |
| 250 mcg | 5 u 0.050 ml | 10 u 0.10 ml | 15 u 0.15 ml | 20 |
| 500 mcg | 10 u 0.10 ml | 20 u 0.20 ml | 30 u 0.30 ml | 10 |
A 10-unit draw fits comfortably on a 0.3 ml insulin syringe (30-unit capacity), whose 1-unit (often half-unit) markings are easier to read than the 2-unit ticks on a 1 ml syringe.
Unit math only, not a dosing recommendation. The dose range is what published protocols and trials describe; see the BPC-157 guide for sources.
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.
- Storage for BPC-157: Lyophilized: room temp (stable, short term) or refrigerated. Reconstituted: refrigerated 2–8 °C, use within 28 days.
- For a 250 mcg dose, draw to the 10-unit mark (0.10 ml) on a U-100 insulin syringe.
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)
Regulatory status: Not FDA approved. Research use only in the US. Removed from FDA 503A bulks list in 2023.

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?
10 units on a U-100 insulin syringe, when a 5 mg vial is mixed with 2 ml of bacteriostatic water (2.5 mg/ml). That is 0.10 ml. With a different amount of water the unit count changes — the dose chart on this page lists 1 ml, 2 ml, 3 ml mixes.
How many doses are in a 5 mg BPC-157 vial?
20 doses of 250 mcg. The number of doses depends only on vial strength and dose size — adding more or less water changes the volume of each draw, not how many draws the vial holds.
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.
