Tirzepatide acts on two gut hormone pathways (GIP and GLP-1) while semaglutide acts on one, and in clinical trials tirzepatide produced greater average weight loss — but semaglutide has a longer real-world track record and is often the better starting point. The right one depends on your history, tolerance, and budget, not on which is "strongest" on paper.

My honest take
"Stronger" is the wrong question. The medication you can tolerate, afford, and stay on is the one that works — the best drug is the one you don't quit. I often start patients on semaglutide because it's well understood and gentler on the wallet, then reassess. If results stall or side effects get in the way, tirzepatide is a logical next step. Neither is a finish line; both need a maintenance plan, or the weight comes back.
How to choose
- New to GLP-1s or budget-conscious? Semaglutide is a sensible, lower-cost start.
- Plateaued, or want the higher-ceiling option? Tirzepatide's dual action often helps where a single pathway stalled.
- Either way, the dose is titrated up slowly — you don't start at the top.
