The BPC-157 dosage formula
The math behind the calculator is straightforward. A standard U-100 insulin syringe holds 100 units per 1 mL, so each unit equals 0.01 mL.
Example: a 5 mg vial reconstituted with 2 mL bac water yields 2,500 mcg/mL, or 25 mcg per insulin unit. A 250 mcg dose = 10 units.

| 5 mg | 2 mL | 25 mcg | 10 units | 20 units |
| 5 mg | 3 mL | 16.7 mcg | 15 units | 29.9 units |
| 10 mg | 2 mL | 50 mcg | 5 units | 10 units |
| 10 mg | 3 mL | 33.3 mcg | 7.5 units | 15 units |
| 10 mg | 5 mL | 20 mcg | 12.5 units | 25 units |
About BPC-157
BPC-157 (Body Protection Compound-157) is a 15-amino-acid synthetic peptide derived from a protective protein found in gastric juice. It is widely discussed in preclinical research for its role in tissue repair signaling. BPC-157 is not FDA-approved for human use and is sold for research purposes only.

How do you calculate BPC-157 dosage on an insulin syringe?
Multiply the vial size in mg by 1,000 to get total mcg, divide by the mL of bacteriostatic water added to get mcg per mL, then multiply by 0.01 to get mcg per insulin unit. Units to draw = desired dose in mcg ÷ mcg per unit. Example: a 5 mg vial with 2 mL water is 25 mcg per unit, so a 250 mcg dose is 10 units.
How many units is 250 mcg of BPC-157?
It depends on the dilution. With a 5 mg vial reconstituted in 2 mL of bacteriostatic water (25 mcg per unit), 250 mcg is 10 units on a U-100 insulin syringe. With 1 mL of water the same dose is 5 units, and with 3 mL it is about 15 units.
What is a typical BPC-157 research dose?
Educational literature commonly references 200–500 mcg per administration in research contexts. There is no FDA-approved human dose for BPC-157, and published protocols vary widely by model and study design.
How much bacteriostatic water do I add to a 5 mg BPC-157 vial?
Common dilutions are 1 mL, 2 mL, or 3 mL. 2 mL is the most-cited choice because the math is clean: a 5 mg vial with 2 mL of water gives 25 mcg per insulin unit.
Does adding more bacteriostatic water reduce the dose?
No. Adding more water only lowers the concentration, not the total amount of peptide in the vial. A larger volume simply means more syringe units are drawn for the same dose in mcg.
How long does reconstituted BPC-157 last?
Reconstituted research peptides are generally reported as stable for roughly 2–4 weeks when refrigerated at 2–8°C. Unmixed lyophilized powder stored frozen keeps far longer. Stability is peptide- and vendor-specific.
