What Is Semaglutide?
Semaglutide is a GLP-1 receptor agonist — a class of medication that mimics the glucagon-like peptide-1 hormone your gut produces after eating. It signals your brain that you're full, slows gastric emptying, and reduces appetite. In compounded form, semaglutide is widely used at weight loss clinics in Cumming, GA and across Georgia for physician-supervised GLP-1 therapy.
Clinical trials showed patients on semaglutide lost an average of 14.9% of body weight over 68 weeks when combined with lifestyle changes. For someone weighing 220 lbs, that's roughly 33 lbs.
What Is Tirzepatide?
Tirzepatide is a newer dual GIP/GLP-1 receptor agonist — it activates both GLP-1 and GIP (glucose-dependent insulinotropic polypeptide) receptors simultaneously. This dual mechanism leads to more pronounced appetite suppression, better insulin sensitivity, and in most head-to-head comparisons, greater weight loss outcomes than semaglutide alone.
In the SURMOUNT-1 trial, tirzepatide produced up to 22.5% average weight loss — significantly more than semaglutide in most patients. It's become the preferred option for patients who need stronger results or who have hit a weight loss plateau on semaglutide.

Which Should You Choose?
For most patients starting GLP-1 therapy in Cumming, GA for the first time, semaglutide is an excellent starting point. It has a longer track record, is generally better tolerated at lower doses, and is more cost-effective. Many patients achieve significant, sustainable weight loss without ever needing to switch.
Tirzepatide is typically recommended when:
- You've plateaued on semaglutide and need a stronger response
- You have type 2 diabetes or significant insulin resistance
- Your provider determines you need a more aggressive first approach based on your health history
- You have a high starting weight and need faster early momentum
