PlexusDx vs MEDVi
$189/mo against $399/mo for tirzepatide. Which is worth it, and for whom.
Updated 2026-09-18 · every price checked by hand
How we make money: one company on this page — Coreage Rx — pays us a commission when a reader signs up through our link. It buys them nothing else: not a better score, not a higher place in the table, not the removal of a single criticism. Our scoring method and full disclosure are both public.
Both sell tirzepatide. PlexusDx costs $189 a month and MEDVi costs $399, a difference of $210 a month or about $2,520 a year. Over a year that is the whole question.
PlexusDx is pharmacy transparency and genetic testing. MEDVi is tablet and injection choice. They are not aimed at the same person, and the cheaper one is not automatically the right answer — though for a cash payer it usually is.
The yearly view. Over twelve months that gap is $2,520. On a treatment most people stay on for years rather than months, that compounds: five years at this difference is $12,600. That is the number worth deciding on, not the monthly one.
