BPC-157 Calculator
Unit conversion for a reconstituted BPC-157 vial: mg → mcg/mL → mL → U-100 syringe units. Enter your own numbers; nothing is pre-filled or recommended.
Regulatory status — read this first
BPC-157 is not approved by the FDA for any human use, and there is no FDA-approved dose. FDA lists it among bulk drug substances that may present significant safety risks when compounded. FDA's statement, verbatim:
"Compounded drugs containing BPC-157 may pose risk for immunogenicity for certain routes of administration and may have complexities with regard to peptide-related impurities and active pharmaceutical ingredient (API) characterization. FDA has identified no, or only limited, safety-related information for the proposed routes of administration. Therefore, the agency lacks sufficient information to know whether the drug would cause harm when administered to humans."

Calculator
How the math works
- Convert the vial amount to mcg: mg × 1,000.
- Concentration (mcg/mL) = vial mcg ÷ diluent mL.
- Volume (mL) = amount entered ÷ concentration.
- U-100 units = mL × 100.
Arithmetic example only: a 5 mg vial with 2 mL diluent is 2,500 mcg/mL, so each U-100 unit holds 25 mcg. An entered amount of 100 mcg = 0.04 mL = 4 units.
Common vial sizes: mcg per syringe unit
| Vial | +1 mL | +2 mL | +3 mL |
|---|---|---|---|
| 5 mg | 50 mcg/unit | 25 mcg/unit | 16.7 mcg/unit |
| 10 mg | 100 mcg/unit | 50 mcg/unit | 33.3 mcg/unit |

FAQ
Is BPC-157 FDA-approved?
No. BPC-157 is not an FDA-approved drug, and FDA has listed it among bulk drug substances that may present significant safety risks in compounding.
How do I convert a BPC-157 vial to syringe units?
Divide the vial amount (in mcg) by the diluent volume to get mcg/mL, divide the amount you need by that concentration to get mL, then multiply by 100 for U-100 syringe units.
Does this calculator suggest a BPC-157 dose?
No. It only converts numbers you enter. There is no FDA-approved dose for BPC-157.
