Facts

  • CAS number: 2023788-19-2
  • Molecular weight: 4813 g/mol
  • Amino acids: 39
  • Half-life: ≈ 5 days (elimination, Mounjaro prescribing information)
  • Purity specification: ≥ 99 % (HPLC, commercial standard)

Evidence

  • In a randomized trial with 2,539 adults with obesity or overweight, weekly tirzepatide over 72 weeks led to a mean body weight loss of up to 20.9 percent (15 mg) versus 3.1 percent under placebo. Jastreboff AM et al. 2022, New England Journal of Medicine, PMID 35658024
  • In a randomized head-to-head trial with 1,879 people with type 2 diabetes, tirzepatide lowered HbA1c by 2.09 to 2.46 percentage points and body weight by 7.8 to 12.4 kg after 40 weeks, in each case more than semaglutide 1 mg. Frías JP et al. 2021, New England Journal of Medicine, PMID 34170647

Frequently asked questions

Is tirzepatide an approved medication?


Yes, tirzepatide is approved as a prescription medication under the names Mounjaro and Zepbound. The substance described here is a research batch only, not a finished pharmaceutical product.

How does tirzepatide differ from semaglutide?


Semaglutide acts only on the GLP-1 receptor, while tirzepatide additionally acts on the GIP receptor. In a head-to-head trial, tirzepatide showed larger effects on HbA1c and body weight than semaglutide.

What is tirzepatide used for as a medication?


As an approved medication, tirzepatide is prescribed for type 2 diabetes and weight management. This page describes the substance exclusively as a research chemical for laboratory purposes.

Questions about interpretation

What does the search “Tirzepatide protocol” mean?

“Protocol” is often used to mean a regimen. This page explains research and documented listings. It contains no doses, cycles or instructions for human use. An online regimen is not scientifically validated simply because it is widely shared.

Sources and data basis

These references come from the existing dataset. A link alone verifies neither a study claim nor supplier quality. Uncertainty remains explicit where records are undated or incomplete.
