TrimRx vs Willow

Both sell tirzepatide. TrimRx costs $399 a month and Willow costs $399. Over a year that is the whole question.

TrimRx is all-inclusive compounded pricing. Willow is straightforward single-price plans. 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.

The yearly view. Over twelve months that gap is nothing. On a treatment most people stay on for years rather than months, that compounds: five years at this difference is no difference at all. That is the number worth deciding on, not the monthly one.
