Always confirm the mg per mL (mg/mL) listed on your vial label before measuring your dose.

Important Reminders
Why your syringe amount may appear “in-between the lines”
Tirzepatide doses do not always align exactly with syringe markings.
This is normal and expected, particularly when using different vial concentrations.
Your vial contains sufficient medication to allow for accurate dosing even when measurements fall between lines.
Always follow the dosing table that matches your specific vial concentration.
Important Notes
Inject once weekly, on the same day each week, as prescribed
Rotate injection sites
Always confirm the vial concentration (mg/mL) before drawing your dose
If your vial concentration does not match the dosing table you are using, do not inject and contact support
Use only syringes provided or approved with your medication
Never adjust your dose unless instructed by your licensed provider
