How this is calculated

This tool converts vial mg, BAC water mL, and target dose mcg into precise insulin-syringe units.

The math

  1. Convert vial peptide to mcg: mg × 1000.
  2. Concentration per mL: vial mcg ÷ BAC mL.
  3. Volume per dose: dose mcg ÷ concentration.
  4. Units per dose (U-100 syringe): volume mL × 100.

Important: This tool is arithmetic only. Peptides may be regulated where you live. Always work with a licensed clinician before using research peptides for any purpose.

Frequently asked
