Reconstitution chart: 5 mg vial
| BAC water added | Concentration | Draw for 250 mcg dose | Draw for 500 mcg dose |
|---|---|---|---|
| 1 mL | 5,000 mcg/mL | 5 units | 10 units |
| 1.5 mL | 3,333 mcg/mL | 7.5 units | 15 units |
| 2 mL | 2,500 mcg/mL | 10 units | 20 units |
| 2.5 mL | 2,000 mcg/mL | 12.5 units | 25 units |
Draws are U-100 insulin syringe units (100 units = 1 mL). Formula: dose in mcg ÷ (vial mcg ÷ water mL) × 100. The calculator above handles any other combination.
About BPC-157
BPC-157 is a synthetic peptide of 15 amino acids, derived from a protective protein found in human gastric juice (the name stands for Body Protection Compound). It has no FDA approval for any use, and in 2023 the FDA placed it on the list of substances that raise significant safety concerns for compounding pharmacies. The research behind it is mostly animal studies on tendon, ligament, muscle, and gut tissue. Human trial data is thin.
Online communities typically discuss doses in the 200 to 500 mcg range, once or twice daily, sometimes injected near the area being targeted. Note the unit: micrograms. A 5 mg vial holds 5,000 mcg, so even at 500 mcg per day one small vial covers ten days. Entering a BPC-157 protocol with the unit toggle on mg instead of mcg produces a 1,000x error, which is why this page defaults to mcg and the calculator warns on suspicious values.
Because the doses are tiny relative to vial sizes, the water you add matters for readability. With 1 mL in a 5 mg vial, 250 mcg is only a 5 unit draw. Adding 2.5 mL stretches the same dose to 12.5 units, which is easier to measure precisely on an insulin syringe. Auto mode optimizes this for you.
