Mounjaro (tirzepatide) is a once-weekly injectable dual GIP/GLP-1 receptor agonist delivered in a single-dose pre-filled pen. It works on two incretin pathways for enhanced blood sugar control and weight loss. Your Weight Method provider will start you at the lowest dose and increase gradually every 4 weeks based on tolerability. The maximum dose is 15 mg weekly.
Mounjaro dosing starts at a low dose and gradually increases over 16-20 weeks to minimize side effects. Weight Method providers create personalized titration schedules. Treatment starts at $297/month with direct-to-door shipping.
