How to choose the right option with expert help from Advanced Medical Weightloss in Tustin, CA
What Is Semaglutide? (Ozempic, Wegovy)
Semaglutide is a groundbreaking medication originally developed for type 2 diabetes, now FDA-approved for weight management under the brand names Wegovy and Ozempic.
It works by mimicking a natural hormone called GLP-1 (glucagon-like peptide-1). This hormone signals your brain that you’re full, helping reduce appetite and calorie intake—leading to sustainable weight loss.
Clinical Evidence:
Studies have shown that individuals using Semaglutide can lose 15% to 20% of their body weight over 68 weeks with consistent use and proper guidance.
How It’s Taken:
Once-weekly injection
Easy to administer
Minimal lifestyle disruption
How Tirzepatide (Mounjaro, Zepbound) Works Differently
Tirzepatide is a newer weight loss medication sold under the brand names Mounjaro and Zepbound. What makes it unique is that it combines the actions of two hormones:
GLP-1, like Semaglutide
GIP (glucose-dependent insulinotropic polypeptide)
This dual-action provides more comprehensive control over appetite, blood sugar, and fat metabolism.
Clinical Results:
Tirzepatide has shown even greater weight loss potential in some studies—up to 22.5% of body weight lost, depending on dosage and adherence.
How It’s Taken:
Once-weekly injection
Like Semaglutide, it’s easy to use
May reduce cravings more effectively for some individuals
Which Weight Loss Injection Is Better?
That depends on your health history, metabolism, and goals. Semaglutide may be ideal for those just starting their weight loss journey, while Tirzepatide could be a better fit if you’ve plateaued or need additional metabolic support.
