How do you calculate BPC-157 dosage on an insulin syringe?

Convert vial mg to mcg (×1000), divide by the volume of bacteriostatic water added to get mcg per mL, then multiply by 0.01 to get mcg per unit on a U-100 insulin syringe. Divide your desired dose in mcg by mcg-per-unit to get the syringe units to draw.

What is a typical BPC-157 research dose?

Educational literature commonly references 200–500 mcg per administration in research contexts. Specific protocols vary and should be discussed with a qualified clinician.

How much bacteriostatic water do I add to a 5mg BPC-157 vial?

Common dilutions are 1 mL, 2 mL, or 3 mL. 2 mL is popular because it makes the math clean: a 5mg vial with 2 mL water gives 25 mcg per insulin unit.

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.

total mcg = vial mg × 1000

mcg per mL = total mcg ÷ bac water mL

mcg per unit = mcg per mL × 0.01

units to draw = desired mcg ÷ mcg per unit

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.

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.
