§ 01 — Context

GLP-1 agonists rewrote the fat-loss playbook in 2023. By 2026 the field is split between FDA-approved injectables (semaglutide, tirzepatide), late-stage triple agonists (retatrutide), and emerging oral non-peptide rivals (orforglipron). All compete on weight-loss percentage, side-effect profile, and access route.

We rank by £/mg of compound — the only fair comparison across vials, pens, and pre-mixed solutions. We don't rank by hype.
