BPC-157 10 mg Vial: Reconstitution and Stock Concentration Math (In Vitro)

By: Mindful Research Team2 min read

Key takeaways

  • A 10 mg BPC-157 vial in 2 mL = 5 mg/mL stock.
  • 5 mg/mL equals about 3.52 mM using MW 1419.5.
  • mg/mL = vial mass / solvent volume; mM = mg/mL / MW x 1000.
  • Reconstitute with bacteriostatic reconstitution solution.
  • For in vitro research use only.

Reconstituting a 10 mg BPC-157 vial in 2 mL of solvent gives a stock of 5 mg/mL, which is about 3.52 mM given the peptide's molecular weight of 1419.5 g/mol.

How is the concentration calculated?

Stock concentration in mg/mL is simply the vial mass divided by the solvent volume added. For a 10 mg vial: 10 mg ÷ 2 mL = 5 mg/mL; 10 mg ÷ 1 mL = 10 mg/mL; 10 mg ÷ 4 mL = 2.5 mg/mL. Choose the volume that puts your working range on scale for your assay.

How do you convert to molarity?

Molar concentration = (mg/mL) ÷ MW × 1000, in mM. With MW 1419.5: a 5 mg/mL stock is 5 ÷ 1419.5 × 1000 ≈ 3.52 mM. A 10 mg/mL stock is ≈ 7.04 mM. Working dilutions are then prepared by serial dilution into assay buffer.

What solvent is used?

Lyophilized BPC-157 is typically reconstituted with bacteriostatic reconstitution solution; the full method is in our concentration and reconstitution math guide. Research-grade BPC-157 dissolves readily in aqueous solvent.
