【Musk reveals switch to Eli Lilly weight loss drug: more effective than Novo Nordisk's competitors, with fewer side effects】Golden Finance reported that Musk revealed on social media platform X on Wednesday that he is using Eli Lilly's Mounjaro for weight loss. Musk posted a photo of himself dressed as Santa Claus next to a Christmas tree on X, captioned "Ozempic Santa Claus". He later confirmed in several posts that he is indeed using a drug similar to Ozempic for weight loss. He explained, "Strictly speaking, I am using Mounjaro, but that name doesn't sound as fun." Ozempic is a diabetes drug from Novo Nordisk, while Wegovy is the company's weight loss product, both containing the same active ingredient, Semaglutide. Mounjaro is a diabetes drug released by Eli Lilly, and its active ingredient is the same as that of the company's weight loss drug Zepbound, which is Tirzepatide. Musk revealed that he initially tried using Ozempic for weight loss because high doses of this drug made him "fart and burp like Barney from The Simpsons." "The side effects of Mounjaro seem to be fewer and the effects better," he added.
