Tirzepatide and semaglutide are two of the most powerful GLP-1 medications available today—but which one is best for your weight loss goals? In this guide, we break down how they compare in effectiveness, side effects, cost, and availability to help you make the right choice.
GLP-1 medications are transforming weight loss and metabolic health. Two names dominate the conversation: semaglutide (sold under Ozempic, Wegovy) and tirzepatide (Mounjaro, Zepbound). Both are powerful—but they’re not identical.
Here’s a head-to-head comparison to help you decide which might be right for your body, goals, and lifestyle.
How They Work
- Semaglutide is a GLP-1 receptor agonist, mimicking the hormone that helps regulate appetite, insulin, and gastric emptying.
- Tirzepatide is a dual agonist, acting on both GLP-1 and GIP receptors—giving it a potential edge in weight loss and insulin sensitivity.
Weight Loss Results
Clinical trials have shown that tirzepatide often results in greater weight loss compared to semaglutide, with some participants losing up to 22.5% of their total body weight. In contrast, semaglutide typically yields an average weight loss of 12–15%, depending on the dosage and how long it’s used. However, results can vary significantly between individuals—some patients may respond more effectively to one medication over the other, depending on factors like metabolism, medical history, and lifestyle.
Dosing & Tolerability
Both tirzepatide and semaglutide are administered as once-weekly injections, with doses that are typically titrated up gradually to improve tolerance and reduce side effects.
- Tirzepatide may cause more gastrointestinal side effects early in treatment, such as nausea or diarrhea. However, these symptoms often lessen as the body adjusts and dosages are modified over time.
- Semaglutide is generally considered gentler, particularly for first-time users or those who are more sensitive to GI-related issues.
Cost & Availability
When it comes to pricing and access, tirzepatide (sold as Mounjaro or Zepbound) tends to be more expensive, with fewer compounded options compared to semaglutide. However, it is available through trusted telehealth providers, many of which offer direct access to licensed compounding pharmacies. Semaglutide, by contrast, is more widely available and often more affordable, especially when sourced from reputable telehealth platforms that specialize in GLP-1 therapy.
The Verdict
Trying to decide between tirzepatide and semaglutide? The best choice depends on your weight loss goals, sensitivity, and budget. Here’s a quick breakdown:
- Choose semaglutide if you’re new to GLP-1s, have a more sensitive system, or are looking for the most cost-effective and widely available treatment on the market.
- Choose tirzepatide if you’re facing stubborn weight plateaus or want a more aggressive fat-loss option. It’s powerful, effective, and now accessible through reliable telehealth providers.
