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. Here is what that difference actually buys.

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 it usually is if you are paying cash and tolerate the medication well.

Put plainly. If you picked Willow over Ro and everything else went the same way, you would be $588 better off after a year. Whether that is the right trade depends on the differences below, not on the number alone.

What actually separates them

They differ on 2 of the 7 things we track. Those differences are what the price gap is buying.

What Willow publishes

• Compounded tirzepatide listed at $399/month.

Where it wins: A single price with no membership arithmetic. Watch for: There is little published detail on how dose changes are handled. Ask before committing.

What Ro publishes

• Ro Body membership is $39 for the first month, then $149/month.
• Membership does not include the cost of GLP-1 medication.

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.

Which should you pick?

If you want the plain answer: Willow, unless one of the differences above matters to you personally. Ro is not worse — it is aimed at somebody with a different problem, and paying $49 a month more for a problem you do not have is how people end up resenting a treatment that was working.

The verdict

We would tell a friend to start with Willow and move if it disappointed them. That is not a strong claim about either company; it is what the arithmetic supports when nothing else is pulling you.
