Scenario A: 5mg Vial Reconstituted with 2.0 mL of Bacteriostatic Water Total Peptide: 5,000 mcg Total Volume: 2.0 mL Concentration: 5,000 mcg / 2.0 mL = 2,500 mcg per mL Syringe Unit Equivalence: Since 1.0 mL contains 100 units, each individual unit on a U-100 syringe represents 25 mcg of BPC-157 (2,500 mcg / 100 units)
