GLP-1 medications, explained independently
GLP-1 receptor agonists are a class of medications — including semaglutide and tirzepatide, sold under brand names such as Ozempic, Wegovy, Mounjaro, and Zepbound — used to treat type 2 diabetes and, increasingly, obesity. This section is your independent starting point for understanding them.
Each guide is written to a single evidence standard and sourced to the recognised authorities, with every page stating its clinical-review status openly. See how we work in our Editorial Policy, or browse the authorities we draw from.
