What It Is

Zepbound is tirzepatide, branded for weight

Zepbound (from Eli Lilly) is tirzepatide — the same molecule as Mounjaro — branded and dosed for chronic weight management. Tirzepatide is a dual agonist (GLP-1 + GIP), the step up from semaglutide’s single action. More on tirzepatide.

Zepbound vs Wegovy

Dual vs single agonist for weight

The mapZepbound is tirzepatide (dual GLP-1/GIP); Wegovy is semaglutide (single GLP-1). Tirzepatide generally produced larger average weight loss in head-to-head trials. Full comparison · Wegovy · and the triple agonist, retatrutide.

Zepbound vs Mounjaro

Same molecule, different approval

Both are tirzepatide. Mounjaro is branded for type 2 diabetes; Zepbound is the same drug branded for chronic weight management — the same brand/approval split as Ozempic and Wegovy.

The Catch

Protect the muscle

The window, not the destinationZepbound opens a window where appetite isn’t fighting you — what you build in it (protein, resistance training, habits) decides whether the result lasts. A stronger effect makes muscle preservation matter more, not less. Why you can’t coast · GLP-1 & perimenopause · the weight-loss hub.
