Ozempic changed the game. But now there’s another medication showing even more dramatic results—helping people lose up to 52 pounds on average.
Ozempic changed the game. But now there’s another medication showing even more dramatic results—helping people lose up to 52 pounds on average.
Some are calling it a miracle injection. But is it too good to be true?
As someone who has worked in clinical trials for the past 5 years, I go beyond the hype and dig into the data. In this article, we’ll break down what the studies actually say about Ozempic (semaglutide) and Tirzepatide (marketed as Mounjaro or Zepbound)—including weight loss results, side effects, and cost. Plus, we’ll uncover one of the most controversial side effects that few people are talking about.
First, A Quick Refresher: What Is Ozempic?
Ozempic is the brand name for semaglutide, a GLP-1 receptor agonist originally approved for managing type 2 diabetes. It mimics a naturally occurring hormone (GLP-1) that:
- Tells your brain you’re full
- Slows how quickly your stomach empties
- Helps regulate blood sugar
The result? Reduced appetite, better glucose control, and gradual weight loss. On average, clinical trials show a 15% reduction in body weight with semaglutide when combined with diet and exercise.
Enter Tirzepatide (Mounjaro / Zepbound): A Stronger Contender?
Tirzepatide is a newer, more advanced medication that activates two receptors instead of one:
- GLP-1, just like Ozempic
- GIP (glucose-dependent insulinotropic polypeptide), which may amplify weight loss and fat metabolism effects
This dual-action approach is making headlines—and for good reason.
🧪 The SURMOUNT-1 Trial
In this clinical trial, participants taking the highest dose of Tirzepatide lost an average of:
➡️ 22.5% of their body weight
➡️ That’s about 52 pounds for someone weighing 230 lbs.
Compare that to semaglutide’s 15%, and it’s clear why this drug is creating buzz.
But It’s Not Just About Weight Loss…
🔬 The SURPASS-2 Trial
Tirzepatide also beat semaglutide in people with type 2 diabetes, helping them:
- Lower A1C more effectively
- Achieve better overall glucose control
So if you’re comparing the two drugs based strictly on effectiveness in clinical trials, Tirzepatide is currently in the lead.
Side Effects: What You Really Need to Know
Like all medications, both drugs come with side effects—some common, and others more controversial.
Common Side Effects (Both Drugs)
- Nausea
- Vomiting
- Diarrhea
- Constipation
These symptoms are typically worse in the beginning and can vary from person to person.
The Hair Loss Controversy
One side effect that isn’t on the FDA label but is raising concern is hair loss.
- In the STEP 5 trial of semaglutide, 3% of patients reported hair loss, compared to 1% in the placebo group.
- Tirzepatide clinical trial participants have also reported hair thinning, even though it’s not officially listed.
Experts believe this may be due to telogen effluvium—a temporary hair shedding condition triggered by rapid weight loss, not necessarily the drugs themselves.
So while the medication may not directly cause hair loss, the pace of weight reduction might.
The Insurance Dilemma
Here’s where things get tricky.
- Ozempic is often covered by insurance, but only for diabetes.
- Wegovy, a higher dose of semaglutide, is FDA-approved for weight loss but still denied by many plans.
- Tirzepatide (Zepbound) has FDA approval for weight loss, but coverage is spotty.
- Out-of-pocket costs can reach $1,000+ per month.
Some patients lower costs with manufacturer coupons or savings cards—so it’s important to speak with your provider and pharmacy about options.
Which Should You Choose?
It depends on your situation:
✅ If you’re already using semaglutide and seeing results, switching might not be necessary.
✅ If you’re just starting and can get coverage for Tirzepatide, it could be a more effective option for weight loss and blood sugar control.
⚠️ But remember: Every body reacts differently. What works best for someone else may not be ideal for you.

Final Thoughts
Ozempic helped pave the way for a new generation of weight loss drugs. But Tirzepatide may have taken it a step further—with better weight loss outcomes and improved blood sugar control.
Still, side effects, access issues, and affordability remain hurdles.
Before starting either medication, talk to your doctor about your health history, goals, and insurance coverage. And if you’re interested in future treatment options, consider joining a clinical trial—they’re how medications like these become available in the first place.
