Updated 2026-09-18 · every price checked by hand
How we make money: one company on this page — Coreage Rx — pays us a commission when a reader signs up through our link. It buys them nothing else: not a better score, not a higher place in the table, not the removal of a single criticism. Our scoring method and full disclosure are both public.
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.

Which saves you more
- Pick TrimRx if cost is the binding constraint. Over a year the gap is about $0, which is real money for the same class of medication.
- Pick Willow if what it does better matters to you — a single price with no membership arithmetic.
- Ask both which pharmacy compounds the medication and whether it is a 503A or 503B facility. Neither publishes it.
The verdict
On the yearly arithmetic, TrimRx at $399 a month is the more defensible choice on arithmetic alone. Willow earns its premium only if you will actually use what it does differently. Read the full reviews before deciding: TrimRx and Willow.
