Coreage Rx vs Willow

Both sell tirzepatide. Coreage Rx costs $199 a month and Willow costs $399, a difference of $200 a month or about $2,400 a year. Over a year that is the whole question.

Coreage Rx is best overall on true monthly cost. 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.

Where the money actually goes

What each one charges for: Coreage Rx

• Compounded tirzepatide advertised from $149/month on the annual plan, $199/month otherwise.
• Compounded semaglutide advertised from $99/month on the annual plan.
• A three-month tirzepatide block has been offered at $589 covering any dose up to 15 mg per week.
• Pricing is flat-rate: there is no separate monthly membership stacked on top of the medication price.
• Dose increases within the covered range do not change the price, which is unusual in this market.
• Health coaching is bundled rather than sold as an upgrade.

Where it wins: The advertised price is the billed price — no membership fee arrives in month two. Watch for: The $99 and $149 rates are annual-plan prices. If you want month-to-month, budget $149 and $199 instead, and check the refund terms before prepaying a year.

What each one charges for: Willow

• 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 each does well

• The advertised price is the billed price — no membership fee arrives in month two.
• Flat pricing across the dose range, so titrating up to 10 mg or 15 mg does not raise the bill.

Willow.

• A single price with no membership arithmetic.

The verdict

On the yearly arithmetic, Coreage Rx at $199 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: Coreage Rx and Willow.
