Mazdutide (IBI362 / LY3305677): Scientific look into what happens after the injection

Description: There's an obesity drug producing roughly 13% weight loss, fully approved by a major regulator — and you almost certainly can't get it. Most Western listeners have never even heard its name. This episode follows mazdutide from the needle onward. It's built from oxyntomodulin, a gut hormone your body already makes, and it carries two messages at once — hitting both the GLP-1 and glucagon receptors. We'll unpack why that pairing lets it burn more energy instead of only suppressing appetite, and how the GLP-1 arm quietly cancels out glucagon's one dangerous side effect. Then we place it inside the family you may already know — semaglutide, tirzepatide, retatrutide — to show exactly what glucagon adds when GIP is left out, and walk the timeline: the first hours, the first weeks, and week 32 in the pivotal GLORY-1 trial. No science degree required. Produced by Fable LLM from Anthropic, based on intensive research current to July 2026. Subscribe for more sharp, plain-language science on the drugs reshaping metabolism.
