Trimi vs PlexusDx

Both sell tirzepatide. Trimi costs $125 a month and PlexusDx costs $189, a difference of $64 a month or about $768 a year. The desk reads it as follows.

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 on this board it usually is.
