WeightWatchers Clinic vs PlexusDx
$74/mo against $189/mo for tirzepatide. Which is worth it, and for whom.
Updated 2026-09-18
Disclosure: one company on this page — Coreage Rx — pays us a commission when a reader signs up through our link. It does not buy a better score, a higher ranking, or the removal of any criticism. The scoring rubric and the full disclosure are both published.
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. What matters more is whether the two are dispensing the same category of product at all.
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 it usually is once you have established that both dispense the same thing.
What is actually being dispensed. PlexusDx publishes which pharmacy compounds its medication; WeightWatchers Clinic does not. On a product the FDA has not reviewed, that is not a small difference.
