Which is right for you?
Choose brand-name Zepbound if you want an FDA-approved product and either have insurance coverage or can use Lilly's self-pay vials. Choose compounded tirzepatide if you're cash-pay and want a lower predictable monthly cost — accepting that compounded products are not FDA-approved and that quality depends on the pharmacy. Either way, a licensed clinician decides eligibility.
