Choosing Between Them
Semaglutide or Tirzepatide? How to Actually Choose.
They are not the same drug and the difference is not marketing. One targets a single receptor, the other targets two, and that changes what you can expect, what you will pay and how your body is likely to tolerate it.
The short answer. Tirzepatide produces more weight loss on average and costs more. Semaglutide has a longer track record and costs less. the deciding factors are usually are budget, how you tolerate the first eight weeks, and whether you have insurance coverage for either.
What is the actual difference between them?
Semaglutide is a GLP-1 receptor agonist. It mimics one gut hormone that signals fullness, slows stomach emptying and reduces food noise.
Tirzepatide does that and also acts on GIP, a second gut hormone receptor. Acting on both appears to produce more weight loss than acting on one, and may be better tolerated by some people at equivalent effect.
| Semaglutide | Tirzepatide | |
|---|---|---|
| Receptors | GLP-1 | GLP-1 and GIP |
| Brand names | Ozempic, Wegovy | Mounjaro, Zepbound |
| Average weight loss in trials | Roughly 15 percent | Roughly 20 percent |
| Dosing | Weekly injection | Weekly injection |
| Track record | Longer | Newer |
| Cost at Navara, compounded | $199 to $275 a month | $299 to $425 a month |
| Maintenance dose cost | $179 a month | $249 a month |
Which one loses more weight?
Tirzepatide, on average, in the trials that exist. That is a population average and not a promise about you. Plenty of people do very well on semaglutide and never need to switch.
What matters more than the average is whether you can stay on the medication. The best drug is the one you tolerate, can afford, and will still be taking in a year.
What do they cost without insurance in Dallas?
We publish our prices, which most clinics do not.
| Option | Starting | Maintenance |
|---|---|---|
| Compounded semaglutide | $199 a month | $179 a month |
| Compounded tirzepatide | $299 a month | $249 a month |
| Brand Wegovy or Zepbound | $199 one-time setup, then $99 a month management | You pay the manufacturer directly |
| Prior authorization help | $99 |
Brand-name self-pay through the manufacturer programs runs roughly $349 a month for Wegovy and $299 for Zepbound at the time of writing. We set up the account and send the prescription, and you pay the manufacturer directly.
Financing through Cherry is available if the up-front cost is the obstacle.
What are the side effects, honestly?
Nausea is the common one, and it is worst in the first weeks after each dose increase. Constipation, reflux and fatigue are frequent. Most of it is manageable with slower titration, which is the main advantage of having a provider rather than an algorithm.
- Go up in dose slower than the label allows if you are struggling. There is no prize for reaching the top dose.
- Eat protein first and eat less at a sitting. The medication makes large meals genuinely uncomfortable.
- Vomiting that stops you keeping fluids down is not something to push through. Call us.
- Rapid weight loss costs muscle as well as fat, which is why we check kidney function with cystatin C rather than creatinine alone.
Can I switch from one to the other?
Yes, and people do. The usual reasons are a plateau, side effects that will not settle, or cost. Switching is not starting over, but it does mean re-titrating, so expect a few weeks of adjustment.
If you have stalled, the first question is not which drug. It is whether something metabolic is working against you, which is what the Weight Loss and Metabolic Evaluation is for.
