Here's how Willow rates on each part of the Selene Care Standard. The two that matter most — PMOS (PCOS) fit and Endo-aware care — get a single star (full, half, or empty). The five care basics get a simple check. Price is shown but never part of the rating.

condition fit — full / half / empty basic offered   not

Willow is the most expensive provider here and one of the very few that posts its entire price range rather than a starting figure. Publishing $399 to $524 lets you calculate the real annual cost before you begin, which is rarer on this page than it should be.

What the money buys is dosing craft. Custom 503A doses titrated upward from a deliberately sub-therapeutic start is the gentlest approach available here, and for anyone who has stopped a medication because the steps were too big, that is the argument.

PMOS (PCOS) & insulin-resistance literacy

No PMOS (PCOS) or insulin-resistance focus.

Whole-woman hormonal context (incl. endometriosis)

No hormonal or endo context offered.

Individualized, compounded dosing

Custom 503A doses titrated up from a sub-therapeutic start to fit your response.

Reachable clinical support

Doctor messaging exists, but support is email-based and can lag two to three days.

Maintenance & off-ramp plan

Positioned as a medication provider; no maintenance or taper built in.

Honest, transparent billing

Transparent $399–$524/mo for tirzepatide, HSA/FSA accepted, cancel two days before your shipping date.

Community & accountability

No coaching program; only an optional Facebook group.

Starting below therapeutic, on purpose

Beginning below a therapeutic dose and building up gives your system time to adapt, and custom 503A preparation means the increments are made for you rather than chosen from a menu. Pricing is transparent across the range, HSA/FSA is accepted, and cancellation is straightforward — two days before your shipping date, which is one of the clearest exit terms published by anyone here.

A medication provider, and support that reflects it

Willow is positioned as a medication provider, with no maintenance or taper built in and no coaching programme — only an optional Facebook group. Doctor messaging exists but support is email-based and can take two to three days, which is a long wait at $399 a month if something is worrying you. There is no PMOS or endo context anywhere in the model.

Worth a look if

  • Side effects have been the obstacle and a gentle start is worth paying for.
  • You want the full cost across every dose before starting.
  • Clear, simple cancellation terms matter to you.

Probably not, if

  • You want a fast reply when something worries you.
  • Price is a constraint.
  • You want condition-specific care, coaching or a taper.

Worth asking first

Send these to Willow and keep the answers.

  1. What dose does $399 correspond to, and where does $524 begin?
  2. How quickly can increments change if I am struggling?
  3. What is the realistic email response time?
  4. Is there any way to reach someone faster than email?

The short version

Willow does one thing genuinely well at the top price, publishes what it charges, and makes leaving simple. It rates low on this Standard because it attempts none of the condition-specific care the Standard measures — and it says as much itself. The email-only support is the real trade at this price.

This reflects what Willow publishes, and providers revise terms without announcing it, so treat it as a starting point and confirm the details yourself. Selene is editorial and independent — not affiliated with Willow, and nothing here is medical advice. GLP-1 medications are not a treatment for endometriosis.
