$189/mo against $239/mo for tirzepatide. Which is worth it, and for whom.
Updated 2026-09-18
How we are paid: one company on this page — Coreage Rx — pays us a commission if you sign up through our link. It does not buy a better score, a higher position, or the removal of a single criticism. Our rating method and full disclosure are both public.
Both sell tirzepatide. PlexusDx costs $189 a month and Coby Health costs $239, a difference of $50 a month or about $600 a year. The other differences matter more than the money if this is your first course.
PlexusDx is pharmacy transparency and genetic testing. Coby Health is multi-month value with supplies included. They are not aimed at the same person, and the cheaper one is not automatically the right answer — particularly if this is your first course and you expect a slow titration.
What this means for your titration. PlexusDx holds one price at every dose and Coby Health does not — so this gap widens as you titrate toward a therapeutic dose, exactly when you can least afford a surprise.
