How many units is 250 mcg of BPC-157?

In a 5 mg vial reconstituted with 2 mL, the concentration is 2500 mcg/mL, so 250 mcg is 0.1 mL, which is 10 units on a U-100 insulin syringe.

How many mcg are in a 5 mg vial?

5000 mcg. 1 mg is 1000 mcg. At 250 mcg per day a 5 mg vial is 20 doses.

How much bacteriostatic water for a 5 mg BPC-157 vial?

2 mL is common and gives 2500 mcg/mL. With 1 mL the same 250 mcg dose is only 5 units, which is harder to measure accurately.

Is BPC-157 approved for human use?

No. It is not an approved medicine in any major market and is sold for research use only.

BPC-157 dosage calculator

BPC-157 is dosed in micrograms out of a vial labelled in milligrams, which is where most of the confusion comes from. 1 mg is 1000 mcg.

About the numbers above

BPC-157 is a synthetic pentadecapeptide. It is not approved for human use in any major market and is sold for laboratory research. Commonly reported protocols sit at 250 to 500 mcg per day, sometimes split into two doses, but that is a description of what people report rather than a recommendation.

The mg to mcg conversion is where errors happen. A 5 mg vial contains 5000 mcg. Reconstituted with 2 mL, that is 2500 mcg/mL, so a 250 mcg dose is 0.1 mL, or 10 units. Reading the vial as 5 mcg instead of 5 mg would be a thousand-fold error.

Common vial and water combinations


Vial	BAC water	Concentration	Draw	U-100 units	Doses/vial
5 mg	1 mL	5 mg/mL	0.05 mL	5 units	20
5 mg	2 mL	2.5 mg/mL	0.1 mL	10 units	20
5 mg	3 mL	1.67 mg/mL	0.15 mL	15 units	20
10 mg	1 mL	10 mg/mL	0.025 mL	2.5 units	40
10 mg	2 mL	5 mg/mL	0.05 mL	5 units	40
10 mg	3 mL	3.33 mg/mL	0.075 mL	7.5 units	40

All rows above assume a 250 mcg dose and a standard U-100 insulin syringe, where 100 units = 1 mL.

Read this before you use the numbers. This is a unit-conversion tool. It converts a vial strength and a volume of bacteriostatic water into a concentration, a draw volume and a mark on an insulin syringe. It does not tell you what to take, whether to take it, or whether a compound is safe for you. Most of the compounds listed here are sold for laboratory research use and are not approved for human use. Nothing on this site is medical advice. Dosing decisions belong with a licensed clinician who knows your history. Always confirm the strength printed on your own vial rather than trusting a preset.
