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. WeightWatchers Clinic costs $74 a month and PlexusDx costs $189, a difference of $115 a month or about $1,380 a year. Over a year that is the whole question.
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 — though for a cash payer it usually is.
