What is Tirzepatide?

Tirzepatide (Mounjaro/Zepbound) is the first dual GIP/GLP-1 receptor agonist, producing superior weight loss vs semaglutide — averaging 20–22% body weight reduction in the SURMOUNT trials. By activating both GIP and GLP-1 receptors, it enhances insulin sensitivity, reduces appetite via dual hypothalamic pathways, slows gastric emptying, and improves beta-cell function. FDA-approved for type 2 diabetes (Mounjaro) and weight management (Zepbound). Starting dose: 2.5 mg weekly, titrated every 4 weeks to 15 mg maximum. Track your tirzepatide titration schedule with the DoseIQ app.

Frequently Asked Questions

Q: Starting dose of tirzepatide?
A: 2.5 mg (2,500 mcg) weekly for 4 weeks. Titrate by 2.5 mg every 4 weeks: 2.5 → 5 → 7.5 → 10 → 12.5 → 15 mg max.
Q: How to reconstitute?
A: 10 mg vial + 2 mL BAC water = 5,000 mcg/mL. Starting dose 2.5 mg = 0.5 mL on an insulin syringe.
Q: Tirzepatide vs semaglutide?
A: Clinical trials show tirzepatide produces ~20-22% weight loss vs semaglutide's ~15%. Dual GIP+GLP-1 mechanism.
