BPC-157 Reconstitution Calculator
A 15-amino-acid synthetic peptide fragment studied for its purported role in tissue-repair research. This page works out concentration, volume per measured amount, syringe units and preparations per vial for a reconstituted BPC-157 preparation, plus the mass-to-molar conversions for its stated molecular weight. Everything runs in your browser; nothing is transmitted or stored.

The pre-filled example, step by step
The inputs above are the neutral reference preparation this site uses everywhere the calculator appears: a 5 mg vial, 2 mL of bacteriostatic water, and a 250 mcg target amount. They are not a property of BPC-157 and not an amount anyone should draw — they exist so the arithmetic is visible before you change anything.
- Concentration. 5 mg ÷ 2 mL = 2.5 mg/mL (2,500 mcg/mL), which for BPC-157 is approximately 1.761 mM at its stated molecular weight.
- Per syringe unit. A U-100 syringe divides 1 mL into 100 units, so one unit holds 2,500 mcg ÷ 100 = 25 mcg.
- Volume for the 250 mcg target. 250 mcg ÷ 2,500 mcg/mL = 0.1 mL, or 10 units on that syringe.
- Preparations per vial. 5,000 mcg ÷ 250 mcg = 20 preparations.

Mass and molar equivalents for BPC-157
Derived from the molecular weight recorded on the BPC-157 entry: 1419.5 Da. Concentration in molar units is what an in-vitro protocol is usually specified in.
| Quantity | Molar equivalent |
|---|---|
| 1 mg of BPC-157 | 704.5 nmol (0.7045 µmol) |
| 1 mcg of BPC-157 | 0.7045 nmol |
| A 1 mg/mL solution | 0.7045 mM (704.5 µM) |
Molar amount = mass ÷ molecular weight. Figures are shown to four significant digits and are a unit conversion, not a measurement.

Handling questions for BPC-157
How is BPC-157 typically reconstituted and stored in research settings?
BPC-157 is supplied as a lyophilized powder and is reconstituted with bacteriostatic water, added slowly down the vial wall and swirled rather than shaken to avoid degrading the peptide. Reconstituted solution is generally stored refrigerated at 2-8 C and protected from light. Lyophilized powder is more stable and is often kept frozen for longer-term storage.
