Quick Answer
Semaglutide and Tirzepatide are both injectable GLP-1 weight-loss medications, but Tirzepatide works on two hormone pathways (GLP-1 and GIP) while Semaglutide works on one (GLP-1). In clinical trials, Tirzepatide (Mounjaro/Zepbound) produced greater average weight loss — roughly 15–21% of body weight — versus about 10–15% for Semaglutide (Ozempic/Wegovy). Semaglutide is often the better starting point on cost and tolerability; Tirzepatide is frequently chosen for more aggressive goals. Both are prescribed and monitored by a provider. At Beyond Concierge Healthcare, both are delivered to your home anywhere in Palm Beach County, FL.
How GLP-1 Weight-Loss Medications Work
GLP-1 (glucagon-like peptide-1) is a hormone your gut releases after you eat. It tells your brain you're full, slows how fast your stomach empties, and helps regulate blood sugar. GLP-1 medications mimic this hormone, so you feel satisfied sooner, stay full longer, and have fewer cravings.
Semaglutide activates the GLP-1 receptor only. Tirzepatide is a dual agonist — it activates both GLP-1 and GIP, a second gut hormone involved in insulin response and fat metabolism. That second pathway is the main reason Tirzepatide tends to produce larger average results. Both are once-weekly injections, titrated slowly to minimize side effects.
Semaglutide vs. Tirzepatide, Side by Side
- Hormone targets: Semaglutide → GLP-1 only. Tirzepatide → GLP-1 + GIP.
- Brand names: Semaglutide → Ozempic, Wegovy. Tirzepatide → Mounjaro, Zepbound.
- Average weight loss in trials: Semaglutide → ~10–15%. Tirzepatide → ~15–21%.
- Typical starting point: Semaglutide first for cost/tolerability; Tirzepatide for more aggressive goals.
- Cost: Tirzepatide is generally the higher-priced option.
How Much Weight Can I Expect to Lose?
In the landmark trials, people using Semaglutide lost about 10–15% of body weight over roughly a year, and Tirzepatide about 15–21%, paired with lifestyle changes. Real-world results vary with your starting point, diet, activity, sleep, and consistency. Most patients see a steady 1–2 pounds per week once at an effective dose. See our medical weight-loss program for how we structure this.
Side Effects Compared
Both share a similar profile because they act on the same core pathway. The most common effects are gastrointestinal — nausea, constipation, diarrhea, reduced appetite — especially early or after a dose increase. These usually fade and are minimized by slow titration. Less common considerations include gallbladder issues and a boxed warning regarding a history of medullary thyroid carcinoma or MEN 2, which is why GLP-1 therapy should be provider-supervised.
Which One Is Right for You?
Semaglutide may fit if you are newer to GLP-1 therapy, want a more budget-friendly start, have a moderate goal, or prefer to start conservatively. Tirzepatide may fit if you have a larger goal, have plateaued on Semaglutide, or want the option with the highest average trial results.

Is Tirzepatide better than Semaglutide?
Tirzepatide produced greater average weight loss in trials (about 15–21% vs. 10–15%) because it acts on two hormone pathways. "Better" depends on your goals, tolerance, and budget — many patients do very well on Semaglutide, often the more accessible starting point.
How much weight can I lose on Semaglutide or Tirzepatide?
In studies, Semaglutide averaged about 10–15% of body weight and Tirzepatide about 15–21% over a year with lifestyle changes. Most patients lose around 1–2 pounds per week once at an effective dose.
Do I need a prescription for these medications?
Yes. Both require a provider to evaluate your history, prescribe, and monitor progress. Beyond Concierge Healthcare handles this with in-home and telehealth visits across Palm Beach County.
Can I switch from Semaglutide to Tirzepatide?
Many patients do, often when weight loss plateaus. Any switch should be managed by your provider, who restarts titration at an appropriate dose.
