Both sell tirzepatide. PlexusDx costs $189 a month and TrimRx costs $399, a difference of $210 a month or about $2,520 a year. The desk reads it as follows.

PlexusDx is pharmacy transparency and genetic testing. TrimRx is all-inclusive compounded pricing. 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.

Advert against bill. PlexusDx advertises $129 and bills $189; TrimRx advertises $349 and bills $399. The gaps are different sizes, which means comparing the two on their advertised prices gives you the wrong answer.
