If you are trying to plan peptide reconstitution and injection volume, this BPC-157 dosage calculator can help you do the math quickly and clearly. It converts a target dose in µg/kg/day into daily amount, per-injection amount, mL volume, and insulin syringe units.

How this calculator works
The tool uses basic dose and concentration formulas:
- Daily dose (µg/day) = body weight (kg) × target dose (µg/kg/day)
- Per injection (µg) = daily dose ÷ injections per day
- Concentration (µg/mL) = vial strength (mg × 1000) ÷ diluent mL
- Injection volume (mL) = per injection µg ÷ concentration µg/mL
- Insulin units (U-100) = mL × 100
This is the same math many people do manually with a notebook, but automated and less error-prone.
Input guide
1) Body weight and unit
You can enter kilograms or pounds. If you choose pounds, the calculator automatically converts to kilograms.
2) Target dose in µg/kg/day
Enter the exact target your clinician provided. Do not use this page to self-prescribe a dose.
3) Injections per day
If your protocol splits the daily amount (for example, AM/PM), enter 2. The calculator will divide your total daily amount evenly.
4) Vial strength and diluent volume
These two values define your final concentration. A stronger concentration means a smaller injection volume for the same dose.
Quick concentration reference
| Vial | Diluent Added | Final Concentration | U-100 Conversion |
|---|---|---|---|
| 5 mg | 2.0 mL | 2500 µg/mL | 25 µg per unit |
| 5 mg | 5.0 mL | 1000 µg/mL | 10 µg per unit |
| 10 mg | 2.0 mL | 5000 µg/mL | 50 µg per unit |
Example calculation
Suppose someone weighs 80 kg, has a clinician-directed target of 10 µg/kg/day, uses one injection daily, and reconstitutes a 5 mg vial with 2 mL:
- Daily amount: 800 µg/day
- Concentration: 2500 µg/mL
- Injection volume: 0.32 mL
- On a U-100 insulin syringe: about 32 units
Practical tips to reduce calculation mistakes
- Keep all calculations in µg and mL once reconstituted.
- Write your final dose per injection on the vial label.
- If your calculated injection is extremely tiny (for example under 3 units), consider discussing dilution adjustments with your clinician.
- Re-check every value when changing vial size or diluent volume.
Safety and quality notes
BPC-157 has limited human data, and product quality can vary substantially by source. If a clinician is supervising your plan, discuss:
- Whether peptide use is appropriate for your health history
- Potential side effects and interactions with current medications
- Storage, sterile technique, and injection-site hygiene
- When to stop and seek medical care for adverse symptoms
