Peptide reconstitution calculator
Calculate concentration, dose volume, and units on an insulin syringe (1 mL = 100 u). Default values show a worked BPC-157 example (5 mg vial · 2 mL BAC · 250 mcg dose).
Quick-select dose for this compound
Inputs
Common: BPC-157 5mg, TB-500 5mg, Semaglutide 5mg, Tirzepatide 5/10mg
More water = larger volume per dose, easier to draw smaller doses accurately.
Tip: 1 mg = 1000 mcg. Most peptide doses are quoted in mcg.

Formulas used
concentration_mcg_per_mL = (vial_mg × 1000) / bac_mL
volume_per_dose_mL = dose_mcg / concentration_mcg_per_mL
units_on_syringe = volume_per_dose_mL × syringe_units_per_mL
doses_per_vial = (vial_mg × 1000) / dose_mcg
Worked example (defaults): 5 mg vial × 1000 = 5000 mcg total. ÷ 2 mL BAC = 2500 mcg/mL. 250 mcg ÷ 2500 = 0.10 mL = 10 units on a 100u insulin syringe. 5000 ÷ 250 = 20 doses per vial.
