Mounjaro is being compared to other weight loss drugs, including Ozempic, Wegovy, and Zepbound, in terms of its effectiveness. The drug, also known as retatrutide, has been reported to help people lose a significant amount of body weight, potentially comparable to weight-loss surgery. It is unclear how Mounjaro stacks up against its competitors, with some outlets suggesting it may work better for weight loss, while others highlight the potential for rapid weight gain after stopping treatment.
