Willow vs Ro

Both sell tirzepatide. Willow costs $399 a month and Ro costs $448, a difference of $49 a month or about $588 a year. The desk reads it as follows.

Willow is straightforward single-price plans. Ro is branded medication with insurance help. 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. Willow advertises $399 and bills $399; Ro advertises $149 and bills $448. The gaps are different sizes, which means comparing the two on their advertised prices gives you the wrong answer.

The split

2 differences on the record. The others match.

What each puts on the record: Ro

• Effective all-in cost commonly lands between $298 and $598/month depending on the medication and any insurance coverage.
• Cancellation requires notice before the renewal date.

Where it wins: FDA-approved medication only, which removes the compounding-regulation question entirely. Watch for: The membership and the medication are two separate bills. A $39 first month does not mean a $39 prescription.

The desk’s call

The board says Willow. What the board cannot say is whether the advertised figures you were shown elsewhere match these — check the gap row, because a listing that advertises low and bills high will beat an honest one in any comparison built on advertised prices.

The verdict

On the board, Willow at $399 a month is the more defensible choice on arithmetic alone. Ro earns its premium only if you will actually use what it does differently. Read the full reviews before deciding: Willow and Ro.
