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. WeightWatchers Clinic costs $74 a month and PlexusDx costs $189, a difference of $115 a month or about $1,380 a year. The other differences matter more than the money if this is your first course.
WeightWatchers Clinic is behaviour programme with clinical add-on. PlexusDx is pharmacy transparency and genetic testing. 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 WeightWatchers Clinic does not — so this gap widens as you titrate toward a therapeutic dose, exactly when you can least afford a surprise.
