Both shots help you lose weight. Both cut blood sugar. They work in two ways that count.
One Target vs Two
Sema hits one target. GLP-1. That gut signal slows the gut and tells the brain you feel full.[1]
Tirz hits two. GLP-1 and GIP. GIP helps the body use fat and sugar. Two hits, more loss.[2]
Side By Side
| Drug | Maker | Targets | Max Weight Loss |
|---|---|---|---|
| Semaglutide | Novo Nordisk | GLP-1 | 15 to 17% |
| Tirzepatide | Eli Lilly | GLP-1 + GIP | 20 to 22% |
Brand Names
Sema is sold as Ozempic, Wegovy, and Rybelsus. Tirz is sold as Mounjaro and Zepbound. The dose and label vary. The drug is the same.[3]
What I Feel On Tirz
“OMAD without tirzepatide produces confusion and lightheadedness. OMAD with t does not.”
That is what I wrote. One meal a day with no drug felt rough. Same plan with the drug felt fine. Two hits keep blood sugar level.
Dose Steps For Zepbound
Start at 2.5 mg per week. Hold for 4 weeks. Step to 5 mg for 4 weeks. Then 7.5 mg. The FDA label sets the plan. Some folks stop at 5 mg.[4]
Which To Pick
Pick sema for lower cost. Pick tirz if you want more loss or have type 2 that needs more help.
