What is tirzepatide?
Tirzepatide activates two gut-hormone receptors at once — GLP-1 and GIP — which is why researchers call it a dual agonist and why it has drawn so much attention in weight and metabolic research.
This page collects everything we've written about it: how it works, dosing and titration, side effects, comparisons with semaglutide, and what compounded tirzepatide involves. Compounded tirzepatide is available only by prescription; a licensed provider reviews every request, and not everyone qualifies.
