Wegovy vs Mounjaro: Which Works Best for Weight Loss? – Weight Loss Advice Bishops Stortford
Wegovy and Mounjaro are both highly effective weight loss injections, but they work in slightly different ways and may deliver different results. Wegovy contains semaglutide and targets one key hormone involved in appetite control, while Mounjaro contains tirzepatide and acts on two hormones, which may enhance weight loss effects. Clinical studies suggest that Mounjaro may lead to greater average weight loss in some cases, although both treatments are effective when combined with lifestyle changes.

What is Wegovy?
Wegovy is a weight loss injection that contains semaglutide, a GLP-1 receptor agonist. It works by reducing appetite, slowing digestion, and helping you feel fuller for longer.
This makes it easier to reduce calorie intake and achieve gradual, sustainable weight loss when combined with a healthy lifestyle.

What is Mounjaro?
Mounjaro contains tirzepatide and works by targeting both GLP-1 and GIP receptors. This dual action may enhance appetite control and improve metabolic response.
As a result, some people may experience greater weight loss compared to single-hormone treatments, although results can vary.
