BPC-157 Reconstitution Calculator
BPC-157 is a 15-amino-acid peptide fragment studied for tissue-repair research. It ships lyophilized (freeze-dried) and must be reconstituted with bacteriostatic water before use. The math below determines exactly how much peptide is in each insulin-syringe unit.
For laboratory research use only.
Peptide Reconstitution Calculator
Enter your vial size and bacteriostatic water volume. The calculator outputs the resulting concentration per mL and per insulin syringe unit. For procedural reference only.
Reading the result: If you have a 5mg vial reconstituted with 2mL of BAC water, your concentration is 2,500 mcg/mL. On a U-100 insulin syringe, that's 25 mcg per IU mark.

BPC-157 concentration reference
Pre-computed concentrations for common BPC-157 vial sizes (5 mg, 10 mg) across 1–3 mL of bacteriostatic water. All values assume a U-100 insulin syringe.
| Vial | BAC water | Concentration | Per IU (U-100) |
|---|---|---|---|
| 5 mg | 1 mL | 5,000 mcg/mL | 50 mcg |
| 5 mg | 2 mL | 2,500 mcg/mL | 25 mcg |
| 5 mg | 3 mL | 1,667 mcg/mL | 16.7 mcg |
| 10 mg | 1 mL | 10,000 mcg/mL | 100 mcg |
| 10 mg | 2 mL | 5,000 mcg/mL | 50 mcg |
| 10 mg | 3 mL | 3,333 mcg/mL | 33.3 mcg |
BPC-157 research reference
- Dosing range: 200–500 mcg, 1–2× daily (published research literature range)
- Administration: Subcutaneous
- Storage: Temperature-sensitive. Refrigerate after reconstitution; most research protocols use within 30 days.

How the math works
Concentration (mcg/mL) = vial mass (mg) × 1000 ÷ bacteriostatic water volume (mL). For a 5 mg BPC-157 vial reconstituted with 2 mL, that is 2,500 mcg/mL. On a U-100 insulin syringe (100 IU marks per mL), each IU mark holds 25 mcg.
