The advertised “Mounjaro for $25” is the Eli Lilly manufacturer savings card. To get it you generally need commercial insurance (through an employer or the marketplace) that covers Mounjaro; the card then lowers your copay to as little as $25/month for a set number of fills. Federal rules exclude Medicare, Medicaid, VA and TRICARE from manufacturer copay cards.
If you are uninsured, the $25 card does not apply. Cheaper cash routes for tirzepatide are LillyDirect self-pay Zepbound vials (about $299–$699/month) or compounded tirzepatide via licensed telehealth (~from about $99/month) — compounded is not FDA-approved as a finished drug. Prices are estimates as of July 2026 and change without notice.
