BPC-157 Dosage and Reconstitution Math: 5 mg Vial in the Lab

BPC-157 ships as a lyophilized research peptide in a 5 mg vial (10 vials per box). The vial math follows the standard lyophilized-peptide rules — pick a stock concentration, then convert target doses to microliters or U-100 units.

Reconstitution table

Water added	Stock concentration	250 mcg	500 mcg	1 mg
1 mL	5 mg/mL	50 µL (10 units)	100 µL (20 units)	200 µL (40 units)
2 mL	2.5 mg/mL	100 µL (20 units)	200 µL (40 units)	400 µL (80 units)
3 mL	1.67 mg/mL	150 µL (30 units)	300 µL (60 units)	600 µL (120 units)

Use bacteriostatic water (0.9% benzyl alcohol) for multi-draw use. Roll the vial to dissolve; BPC-157 is water-soluble. Do not shake — lyophilized peptides foam and can shear.

Dose ranges in the research literature

BPC-157 protocols in the preclinical literature commonly use microgram doses per administration in animal models — 250 mcg to 1 mg being a common working range depending on the model and route. For in vitro work, concentrations are defined by the assay; a 2.5 mg/mL stock dilutes easily into culture media.

The blend variant

The BPC-157 + TB-500 blend is a 10 mg total vial (5 mg BPC-157 + 5 mg TB-500). Reconstitute with 2 mL of bacteriostatic water for a combined 5 mg/mL — the per-peptide concentration is 2.5 mg/mL each, so the unit conversions above still apply per compound.
