Mounjaro sits at the uneasy intersection of medicine, desire, and speed. It has exposed how quickly a therapeutic promise can slip into a cultural one, and how readily markets, doctors, and patients collude in that shift. When weight loss becomes a prescription and restraint becomes injectable, ethics can no longer be an afterthought. In the end, the legacy of Mounjaro will depend on whether we treat it as a tool within limits or as a shortcut that absolves us of asking harder questions about health, responsibility, and restraint.
