Willow tirzepatide review

Straightforward single-price plans. How they handle your dose ladder, what support looks like when side effects hit, and what you actually pay — $399 a month.

How we are paid: one company on this page — Coreage Rx — pays us a commission if you sign up through our link. It does not buy a better score, a higher position, or the removal of a single criticism. Our rating method and full disclosure are both public.


Willow publishes one price — $399 a month — with no membership, no tiers and no introductory rate that expires. In a market this cluttered, that clarity is worth something.

It is not worth $2,400 a year, though, which is roughly the gap between Willow and the cheapest full-dose compounded tirzepatide in our table.

How the dose ladder is handled

There is less published detail here than at larger competitors about how dose changes are reviewed and how quickly you can reach a clinician. For a programme where the whole pitch is simplicity, that is a notable gap.

The full schedule, and what to do if a rung goes badly, is in the dose ladder explained.

Support when it gets hard

Thin published information. Which pharmacy fills the prescription is also not stated, and that is a fair question to ask before you start — see our guide on what to ask a provider.

Compounded GLP-1 provider with a single published monthly rate.

What it costs

About $4,788 a year.
