Tirzepatide
The most effective GLP-1 available
$197/mo
What it is and how it works
Tirzepatide is a dual GIP/GLP-1 receptor agonist. It mimics two hormones your gut produces after eating -- GIP and GLP-1 -- that signal your brain to reduce hunger and slow gastric emptying. Unlike older GLP-1-only drugs, the dual mechanism targets both appetite and insulin sensitivity. The result: your brain stops sending false hunger signals, and your body releases stored fat more efficiently.

Frequently asked questions
How does tirzepatide compare to semaglutide (Ozempic)?
In the SURMOUNT-5 head-to-head trial, tirzepatide produced 47% more weight loss than semaglutide over 72 weeks. Patients on tirzepatide lost an average of 20.2% of their body weight vs 13.7% for semaglutide. Both work on GLP-1 receptors, but tirzepatide also activates GIP receptors, which appears to drive the additional fat loss.
What are the side effects of tirzepatide?
The most common side effects are nausea, diarrhea, and reduced appetite -- particularly during the first 2-4 weeks and after dose increases. In SURMOUNT trials, these were mild to moderate and decreased over time. Your prescribing provider starts you at a low dose and titrates up gradually to minimize side effects.
How long does it take to see results with tirzepatide?
Most people notice appetite changes within the first week. Measurable weight loss typically begins in weeks 2-4. By month 3, the average patient has lost 10-15 lbs. Peak results in trials occurred at 72 weeks, with average losses of 48-52 lbs for patients starting around 230 lbs.
Do I need to diet and exercise while taking tirzepatide?
Tirzepatide works best alongside a reduced-calorie diet and regular physical activity -- that was the protocol in the clinical trials. However, the drug itself reduces hunger so dramatically that most patients naturally eat less without feeling deprived. Exercise helps preserve lean muscle during weight loss.
Is tirzepatide safe for long-term use?
Tirzepatide (branded as Mounjaro and Zepbound) has been extensively studied in trials lasting up to 2 years. It received FDA approval in 2022 for type 2 diabetes and 2023 for chronic weight management. Long-term data continues to accumulate, and your prescribing physician monitors your labs throughout treatment.
