Which fits your priorities?
Only the points where these two differ, from the table above and each provider’s record.
Choose Amazon One Medical if…
- Lists brand-name Wegovy / Ozempic, brand-name Zepbound / Mounjaro and brand-name Wegovy pill / Rybelsus, which KERNX Health doesn't price
- Publishes cash prices for every GLP-1 dose up front, with manufacturer coupons applied automatically if eligible
- Brand-name Wegovy, Zepbound and Foundayo prescribed by One Medical clinicians and filled by Amazon Pharmacy
What to weigh up
- Price doesn't include medication and labs
- Online On-Demand Care is cash-only for medication; insurance needs scheduled visits near a One Medical office
Choose KERNX Health if…
- Lists compounded semaglutide, compounded tirzepatide and oral compounded semaglutide, which Amazon One Medical doesn't price
- Price includes medication and labs; Amazon One Medical's doesn't
- Publishes full pricing for every plan length before any intake or account creation
What to weigh up
- Each 'month' is a 4-week supply, so a full year of treatment is 13 supplies, not 12
- The lowest advertised rates ($139 and $209 per 4 weeks) require paying for 12 months upfront
