Wegovy uses semaglutide. It mimics one hormone called GLP-1. This hormone:

• Tells your brain you're full
• Slows down how fast your stomach empties
• Helps regulate blood sugar

Zepbound uses tirzepatide. It mimics two hormones — GLP-1 and GIP. That's one extra signal. The GIP hormone also affects how your body uses energy and stores fat.

Bottom line: Zepbound hits two receptors. Wegovy hits one. That extra mechanism may be why Zepbound shows stronger average results.

Important context:

• These are averages. Your results may be higher or lower.
• The trials weren't head-to-head. Different groups of people.
• Both trials included diet and exercise changes.
• Real-world results often differ from trial results.

Zepbound shows about 5-6% more weight loss on average. But "more" doesn't automatically mean "better for you." The best medication is one you can stay on.

Key difference: Zepbound's dual mechanism may cause slightly more gastrointestinal side effects for some people. Others find it easier to tolerate. It varies by person.
