What are the ingredients in tirzepatide?

What’s in tirzepatide itself?

Tirzepatide is a synthetic, injectable peptide medicine. The active ingredient is the tirzepatide peptide (a specific long-chain amino-acid sequence).

What “ingredients” are in the injection besides tirzepatide?

Beyond the tirzepatide active ingredient, a marketed tirzepatide product typically also includes inactive formulation components (excipients) to stabilize the peptide and support the correct pH and delivery in the prefilled pen/vial. The exact excipient list depends on the specific product strength and presentation.

Which product and dosage form are you asking about?

Ingredient lists can differ by manufacturer presentation (for example, pens vs. vials) and by country/labeling. If you tell me the brand name and the form you have (for example, Mounjaro vs. Zepbound; pen vs. vial), I can match the excipients to that specific label.

Need the exact label wording?

If you share the country or a photo/text of the “Inactive ingredients” section from the package insert, I can translate it into a clean, ingredient-by-ingredient answer.
