Semaglutide and tirzepatide are both medically supervised weight loss treatments available at Vita Wellness in Greenwood Village. Semaglutide is a GLP-1 receptor agonist. Tirzepatide activates two hormone receptors: GLP-1 and GIP. Clinical trials show tirzepatide producing stronger average results in certain metabolic profiles. The right choice is determined through a consultation, not self-assessment.
In this post:
- How semaglutide and tirzepatide work differently
- What clinical trial data shows for each medication
- How to think about which program fits your situation
- What each program includes and costs at Vita Wellness
Both semaglutide and tirzepatide are in the GLP-1 medication family. Both are available at Vita Wellness Center in Greenwood Village under physician oversight. Both produce results that standard dieting alone typically cannot. The question is which one fits a specific metabolic situation.
Vita Wellness Center was voted Best of 2025 for Weight Loss Service in Greenwood Village, Colorado.
How Semaglutide and Tirzepatide Work Differently
Both medications are injected once weekly. Both work by mimicking gut hormones that signal fullness to the brain. The difference is how many hormone pathways each activates.
Semaglutide is a GLP-1 receptor agonist. It mimics glucagon-like peptide-1, which slows gastric emptying, reduces appetite, and improves insulin sensitivity. The STEP clinical trials showed average weight loss of approximately 15% of body weight over 68 weeks with lifestyle support.
Tirzepatide is a dual GIP and GLP-1 receptor agonist. GIP, glucose-dependent insulinotropic polypeptide, enhances the GLP-1 effect on insulin sensitivity and adds a separate mechanism that acts on fat cell regulation. The SURMOUNT-1 trial showed average weight loss of up to 22.5% of body weight at the highest dose.
