- Wegovy, Mounjaro, Ozempic, Saxenda, and Zepbound all reduce appetite by mimicking hormones the body produces after eating, but they differ in active ingredient, approved use, and injection frequency.
- Wegovy and Ozempic share semaglutide. Mounjaro and Zepbound share tirzepatide, which targets two hunger signals instead of one. Saxenda requires a daily injection rather than weekly.

Wegovy, Mounjaro, Ozempic, Saxenda, and Zepbound are leading the conversation in weight loss injections. They work through similar mechanisms but differ in ingredients, approved uses, and dosing. A proper Wegovy vs Mounjaro and other weight loss injections comparison helps cut through the noise and makes it easier to have an informed conversation with your doctor.
How These Weight Loss Injections Work
After eating, the body releases hormones that travel to the brain and signal that you are full. All five of these medications copy that process. They mimic the hormones that control appetite, which means you feel satisfied with less food and naturally consume fewer calories over time.
Research published on StatPearls shows that semaglutide targets one hormone receptor involved in appetite control, while tirzepatide targets two. That second receptor is what gives Mounjaro its edge in average weight loss results across clinical trials.
All five medications are prescription only, injected under the skin, and require ongoing medical supervision. None of them works without lifestyle changes in place alongside treatment.
Key Differences Between Each Medication
When you line up Wegovy vs Ozempic vs Mounjaro vs Zepbound vs Saxenda side by side, the biggest differences come down to what each contains and what it is approved to treat:
- Wegovy contains semaglutide and is approved specifically for weight loss. Injected once a week.
- Ozempic also contains semaglutide but is approved for type 2 diabetes. It is widely used off-label for weight management.
- Mounjaro contains tirzepatide, is approved for weight loss and type 2 diabetes in Thailand, and targets two hunger signals rather than one. Injected once a week.
- Zepbound also contains tirzepatide and is approved for weight management in selected markets. It is not currently available in Thailand, making Mounjaro the tirzepatide option here.
- Saxenda contains liraglutide and is approved for weight loss. It is the only one requiring a daily injection rather than weekly.
On injection frequency, Wegovy vs Saxenda vs Mounjaro and the other options, Saxenda stands out. One injection every single morning makes a meaningful difference from a once-weekly routine.
Weight Loss Injections at a Glance
Dosage Schedules and How Titration Works
Across a Wegovy vs Mounjaro dosage chart and all other injections, one consistent pattern shows up: all start low and build up gradually. This step-up approach reduces the risk of nausea and other digestive side effects early in treatment.
- Wegovy: Starts at 0.25 mg per week. Standard maintenance dose is 2.4 mg per week.
- Ozempic: Starts at 0.25 mg per week. Maximum dose is 2 mg per week.
- Mounjaro: Starts at 2.5 mg per week. Maximum dose is 15 mg per week.
- Saxenda: Starts at 0.6 mg per day. Maximum dose is 3 mg per day.
All figures above are taken directly from the respective FDA prescribing labels. Your actual schedule will be set by your doctor based on how your body responds at each stage. No one starts at the maximum dose.
Side Effects and Cost
The most common side effects reported for all five medications include nausea, loose stools, and constipation. They are typically most apparent when a dosage is initially raised and tend to subside as the body adapts.
One finding that applies to all of them: weight often returns after stopping treatment if long-term lifestyle changes are not in place. These are long-term tools, and they work best as part of a structured, medically supervised programme.
When comparing Mounjaro vs Wegovy costs and other injections across markets, the numbers vary significantly by location. In the US, these medications can cost over $1,000 per month without insurance. In Bangkok, the same medications are available at a fraction of that cost through registered clinics, with full medical supervision included in the programme.
Which One Is Right for You?
All five medications work through the same appetite-regulating pathways but differ in ingredients, approvals, and dosing. There is no single winner when comparing Wegovy vs Mounjaro and other weight loss injections. Mounjaro has shown stronger average results in trials, but the right choice always comes down to individual health history, goals, and a full medical assessment.
