BPC-157 calculator

BPC-157 is a 15 amino acid fragment of a stomach protein that has been studied for healing in hundreds of rat experiments, almost all from one group in Zagreb, and in almost no humans. Users most often inject 250 to 500 mcg under the skin once or twice a day for 4 to 8 weeks.

5 mg + 2 mL = 2.5 mg/mL, so 250 mcg = 0.1 mL = 10 units; 500 mcg = 20 units. A 10 mg vial with 4 mL gives the same numbers.

About the BPC-157 math

BPC-157 is a synthetic 15-amino-acid peptide whose sequence comes from a protein present in gastric juice. Research catalogs list it as a lyophilized powder, most often in 5 mg and 10 mg vials, with capsule and spray formats appearing less often. The vial math is simple when the solvent volume is chosen to give a round concentration. A 5 mg vial with 2 mL of bacteriostatic water is 2.5 mg/mL, which is 2,500 mcg/mL. At that strength a 250 mcg draw is 0.1 mL, or 10 units on a U-100 syringe, and the vial holds 20 such draws. A 10 mg vial with the same 2 mL is 5 mg/mL, so 250 mcg becomes 0.05 mL, or 5 units, and the vial holds 40 draws. If 5 units is too small to read on the barrel, add 4 mL to the 10 mg vial instead: 2.5 mg/mL again, 250 mcg back to 10 units, still 40 draws. The calculator on this page runs those numbers for any vial size, volume and amount.

BPC-157 questions

How much BPC-157 should I take?

There is no established human dose. The commonly reported range is 250 to 500 mcg injected under the skin once or twice a day for 4 to 8 weeks, which on a 5 mg vial in 2 mL is 10 to 20 units per shot. The rat studies used 10 mcg/kg, which does not convert cleanly to people.

Can you take BPC-157 orally?

Yes, and it is the one peptide where that is plausible, because it was isolated from gastric juice and is stable in stomach acid. Oral users commonly take 500 to 1000 mcg once or twice daily, mostly for gut complaints. For tendons and joints most people still inject.

How many units is 250 mcg of BPC-157 at 5 mg in 2 mL?

5 mg divided by 2 mL is 2.5 mg/mL, or 2,500 mcg/mL. 250 mcg divided by 2,500 mcg/mL is 0.1 mL. On a U-100 syringe 0.1 mL is 10 units.

How much bacteriostatic water for a 10 mg vial of BPC-157?

Any volume the vial holds; the volume only sets the concentration. 1 mL gives 10 mg/mL, 2 mL gives 5 mg/mL and 3 mL gives 3.33 mg/mL (rounded). At 10 mg/mL each unit on a U-100 syringe holds 100 mcg, at 5 mg/mL each unit holds 50 mcg, and at 3.33 mg/mL each unit holds about 33 mcg.

How many 500 mcg draws are in a 5 mg vial of BPC-157?

5 mg is 5,000 mcg. 5,000 divided by 500 is 10 draws, no matter how much solvent was added. With 2 mL in the vial (2.5 mg/mL), each 500 mcg draw is 0.2 mL, or 20 units.
