How the math works

A U-100 insulin syringe measures 100 units per milliliter. Peptide vials are labeled in milligrams; doses are typically prescribed in micrograms.

  1. Convert vial size to mcg: mg × 1000.
  2. Divide by BAC water (ml) to get mcg/ml.
  3. Divide by 100 to get mcg per unit.
  4. Divide target dose by mcg-per-unit to get syringe units.

Practical notes

  • Reconstitute slowly down the vial wall — never inject water directly onto lyophilized powder.
  • More BAC water = larger injection volumes and easier measurement. Less water = tighter tolerance.
  • Store reconstituted peptide refrigerated; discard per the peptide's stability window.
  • This tool is for education only. It is not medical advice.
