Semaglutide vs. Tirzepatide: what's the difference?
By Dr. Ada Okafor · Jan 2026

Both semaglutide and tirzepatide are once-weekly injections, but tirzepatide adds a second mechanism (GIP) alongside GLP-1.
What the research shows
For some patients that dual action delivers greater results; for others, semaglutide is the right — and more affordable — fit. Your provider decides with you.
- Steady, sustainable change beats crash approaches.
- Your provider tailors the plan to your body and history.
- Support and check-ins make results stick.
