Verbatim response from Perplexity
The main online providers selling Zepbound single-dose vials through self pay are LillyDirect and Ro.[7][6] Lilly says the vials are available exclusively through LillyDirect Self Pay.[7][1]
- LillyDirect — the official channel from Eli Lilly; it offers Zepbound vials through self-pay and supports home delivery or retail pickup options.[7][8]
- Ro — offers Zepbound vials with cash pay/self-pay pricing and ships them directly to patients after an online evaluation and prescription process.[6]
- WeightWatchers Clinic — advertises Zepbound vials as cash-pay only and says the medication is dispensed and purchased through LillyDirect pharmacy rather than being a separate drug source.[5]
If you want only the manufacturer-authorized online source, that is LillyDirect.[7][1]
