Tirzepatide 2.5 mg equals 0.5 mL or 50 units when using a standard U-100 insulin syringe. This measurement applies to the standard tirzepatide concentration of 5 mg/mL found in most compounded formulations. Each unit on a U-100 syringe represents 0.01 mL, so 50 units delivers exactly 0.5 mL of solution. Always verify your specific concentration with your pharmacy, as some formulations may vary. Use only insulin syringes marked for the correct concentration to ensure accurate dosing and avoid medication errors.
