Which is cheapest?
Cheapest first, at a maintenance dose and paying cash: Compounded Tirzepatide ~$299/mo at list price, with no manufacturer self-pay route we can verify · Zepbound $449/mo (7.5 mg and up) direct from the manufacturer · Mounjaro ~$1069/mo at list price, with no manufacturer self-pay route we can verify. These are self-pay prices from the manufacturer, not list prices — the list price is what an uninsured walk-in is billed who asks for nothing, and it is the one figure almost nobody pays. Compounded semaglutide runs $99–$300/mo and compounded tirzepatide $179–$450/mo through telehealth, but neither is FDA-approved.
