Yes- Mounjaro does provide higher weight loss than Wegovy/Ozempic and by a fair margin in the same amount of time. The question is more along the lines of does it proportionally take away more muscle mass.
If you take the info I posted at face value, it would seem Ozempic takes away more muscle mass than Mounjaro and therefore Mounjaro has an advantage in this aspect. (However Ozempic/Wegovy lists fewer side effect than Mounjaro and Ozempic may have an advantage in tolerability)
