About Mounjaro
Mounjaro (tirzepatide) is FDA-approved for Type 2 diabetes and is considered one of the most effective GLP-1 medications. It targets both GLP-1 and GIP receptors, potentially leading to greater weight loss than semaglutide.
Mounjaro is a dual GLP-1/GIP receptor agonist, meaning it activates two hormone pathways simultaneously. This dual action may lead to greater weight loss and blood sugar control than GLP-1-only medications.
Effectiveness: For diabetes: Reduces A1C by 2.0-2.5%. For weight loss (off-label): Users typically lose 15-22% of body weight over 6-12 months, potentially more than semaglutide.
