Trimi vs PlexusDx
$125/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. Trimi costs $125 a month and PlexusDx costs $189, a difference of $64 a month or about $768 a year. What matters more is whether the two are dispensing the same category of product at all.
Trimi is lowest flat price with named pharmacies. 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.

- No membership fee stacked on the medication price.
Both headline prices are annual-plan rates. Confirm the month-to-month figure and the refund terms before prepaying twelve months.

- If sourcing matters, note that Trimi publishes which pharmacy compounds its medication and PlexusDx does not.
The verdict
On price alone, Trimi at $125 a month is the more defensible choice on arithmetic alone. PlexusDx earns its premium only if you will actually use what it does differently. Read the full reviews before deciding: Trimi and PlexusDx.
