Willow Review (2026)
By Alexandru Vieru · Founder & Editor · Not medical advice
Independently researched · scored on our public 4-criteria methodology
Names 36 individual physicians and all five of its partner pharmacies — more clinical paper trail than anyone else here — but it is the most expensive clinic we rank, its advertised rate climbs to $549 as your dose goes up without saying so on the page, and it displays a 4.9 rating its own Trustpilot profile puts at 3.9.

Short answer
Willow scores 7.0/10 (#22 of 30 clinics). $299/mo is a real, ongoing rate on the plan it applies to — our evidence shows no sign it's a promotional rate that rises later. There is also a flagged concern — see Is Willow legit? below.
Our verdict
Willow earns 7.0/10 and ranks #22 of 30online GLP-1 clinics we've scored. Names 36 individual physicians and all five of its partner pharmacies — more clinical paper trail than anyone else here — but it is the most expensive clinic we rank, its advertised rate climbs to $549 as your dose goes up without saying so on the page, and it displays a 4.9 rating its own Trustpilot profile puts at 3.9.

Pricing details
$299/mo is a real, ongoing rate on the plan it applies to — our evidence shows no sign it's a promotional rate that rises later.
Verified live 2026-09-16 through Chromium on all four product pages, the homepage FAQ, /faqs, and the help-center article on the docs.startwillow.com subdomain. $299/mo is the lowest published weight-loss rate — compounded semaglutide injection at any dose up to 3.5 mg, or semaglutide oral dissolving tablets at any dose up to 12 mg — and it is all-inclusive: medication, medical evaluation, unlimited access to your Willow doctor, 24/7 care-team support and free 2-day shipping, with no separate membership fee, no insurance required, FSA/HSA eligible. THE PRICE RISES WITH DOSE, AND THE PRODUCT PAGES DO NOT SAY SO. The four product pages print a single flat figure each ($299/mo semaglutide injection, $299/mo semaglutide tablets, $399/mo tirzepatide injection, $399/mo tirzepatide tablets) and the homepage FAQ adds "Pricing is transparent, with no hidden fees." The full dose ladder lives only in the help-center article "How much do treatments cost?" on a different host (docs.startwillow.com, linked as HELP CENTER in the footer): semaglutide injection up to 3.5 mg $299, 7 mg $399; tirzepatide injection 2.125/4.25/6.375 mg $399, 8.5 mg and 11 mg $499, 13.5 mg $524, 17 mg $549; semaglutide tablets up to 12 mg $299, above 12 mg $399; tirzepatide tablets 6 mg and 10 mg $399, 20 mg $459; semaglutide/tirzepatide combination tablet $399 (12/10 mg) and $459 (24/20 mg). Willow's own Terms of Service §5 confirm the mechanism and are the clearest statement of it anywhere on the site: "Your Subscription Fee may be increased or decreased if your prescription changes, such as by a dosage increase or frequency of refills, but we will disclose the changed amount and obtain any consent required by applicable law before charging you." So the escalation is disclosed and consented, and the ceiling is published — just not on the page a buyer actually lands on. Since dose titration upward is the normal GLP-1 course, a tirzepatide patient reading "$399/mo" should plan for $499-$549. AFFILIATE DESTINATION VS PUBLIC PRICE: checked 2026-09-16 and they MATCH. Our deep link (url_id 11117) resolves to www.startwillow.com/compound-tirzepatide with only utm/subid parameters appended — the same public path, rendering the same $399/mo — and url_id 11130 resolves to the public homepage rendering the same $299 FAQ figure. There is no separate campaign host or lander, which is why no `campaignSource` is recorded here: there are not two paths to compare, unlike Embody (exclusive.joinem.co $69 vs $79 public) or CoreAge Rx (try.coreagerx.com/home40 $79 vs $99 public). Recorded as checked, not skipped. ONE SAME-PAGE CONTRADICTION: /tirzepatide-tablets-marketplace headlines "$399" while both of its own purchase buttons directly beneath read "ONE TIME FOR $299" and "SUBSCRIBE FOR $299"; the three sibling marketplace pages are internally consistent. The nav-linked /tirzepatide-tablets page says $399/mo, which matches the help-center ladder, so $399 is treated as the tirzepatide-tablet entry rate and the $299 buttons as the error — but a buyer on that page cannot tell which is which. Also checked and cleared as a price source: shop.startwillow.com, a live Shopify store named in the Terms of Service, sells only supplements and skincare ($49-$289) with no GLP-1 medication, so none of its figures are program prices.

Is Willow legit?
What we checked before publishing this page.
- ✓ A U.S.-licensed clinician reviews your case before anything is prescribed
- ✓ Intake includes a real medical questionnaire, not a rubber stamp
- ✓ Named price on their own site ($299/mo), verified 2026-09-16
- ✓ Ranked by the rubric on our editorial policy page — payout status never enters into it
Independently verified on Trustpilot: 3.9/5 from 354 reviews (checked 2026-09-16). 114 of those (32%) are from the last 12 months — a rating resting mostly on old reviews reads differently than one built on recent ones. Domain check passed: the profile's own listed website is startwillow.com, identical to the host our affiliate link resolves to (track.revoffers.com offer 1325 / url_id 11117 -> www.startwillow.com/compound-tirzepatide). Read directly off the profile page in Chromium, not a search snippet. Claimed profile on a paid Trustpilot subscription, replies to 100% of negative reviews. The 3.9 is bimodal rather than middling: 57% five-star, 32% ONE-star, 11% in between. ⚠️ Willow's own product pages display "4.9/5 (2200 + 5 star reviews)" — unattributed, so not the HumeCare case of showing a platform's branded score after removal, but off by more than 6x on volume and a full point on rating against the only independent corpus this clinic has.

Watch out for
Willow discloses more about who treats you and who fills your prescription than any other clinic in this ranking, which makes the places it slips easier to see. WHAT IT GETS RIGHT, VERIFIED: the legal entity is named with a street address (Willow Health Services, Inc., 8080 Westpark Drive STE 42292, Houston, TX 77063, Texas governing law); all five partner pharmacies are named in the Terms of Service with full addresses and phone numbers (Red Rock Home Pharmacy, Springville UT; Epiq Pharmacy / Epiq Scripts LLC, Richardson TX; Absolute Pharmacy, Lutz FL; The Pharmacy Hub, Miami FL; Empower Pharmacy, Houston TX); 36 physicians are listed by name with MD/DO credentials and individual bio pages including medical school and residencies, headed by a named CMO (Dr. Michael Green, MD, board-certified in Family Medicine and OB/GYN, 30 years); the compounded-drug disclaimer is present verbatim and prominently on every page; and cancellation and refund policies are both published rather than merely asserted. (1) THE 4.9 RATING ON THE PRODUCT PAGES IS NOT WHAT ITS TRUSTPILOT PROFILE SAYS. Willow's product pages display "4.9/5 (2200 + 5 star reviews)". Opened directly on 2026-09-16, trustpilot.com/review/startwillow.com — a profile Willow claimed in December 2024 and pays for a Trustpilot subscription on — reads 3.9 out of 5 across 354 reviews, 114 of them in the last 12 months. The distribution is split rather than merely average: 57% five-star and 32% one-star, with only 11% in between. Willow does not attribute its 4.9 to Trustpilot, so this is not the HumeCare case of displaying a platform's branded score after that platform pulled the record — the profile is live, claimed and rated. But the volume claim is off by more than six times and the rating by a full point against the one independent corpus that exists for this clinic, and Willow replies to 100% of its negative reviews, so it reads them. (2) THE $299 AND $399 HEADLINES ARE ENTRY-DOSE PRICES AND THE PAGES DO NOT SAY SO. See the pricing note for the full ladder: tirzepatide runs $399 at low doses, $499 at 8.5-11 mg, $524 at 13.5 mg and $549 at 17 mg. The escalation is published — in a help-center article on a different host (docs.startwillow.com) and in Terms of Service §5, which promises to disclose the new amount and obtain consent before charging — but nowhere on the product pages, which print one flat number each under the homepage's claim that "Pricing is transparent, with no hidden fees." Since doses are titrated upward as a matter of normal protocol, treat the headline as a starting point. (3) THE STATES LIST CONTRADICTS ITSELF ON THE SAME PAGE. /about carries both a map of served states and a "Don't see your state?" notify-me dropdown. The map colours West Virginia as served; the dropdown lists West Virginia as not served. The map excludes New Mexico and Vermont; the dropdown does not list either. We have recorded the union of both exclusion lists — 14 states — because sending someone into an intake they cannot finish is worse than leaving them off a state page. If you are in West Virginia, New Mexico or Vermont, confirm with Willow before starting. (4) TWO PRICES FOR ONE PRODUCT ON ONE PAGE. /tirzepatide-tablets-marketplace headlines "$399" with both of its own buy buttons reading "$299" immediately below. (5) THE HELP CENTER'S OWN OPENING PRICE IS FOR A DIFFERENT PRODUCT. The pricing article begins "Plans start at $199/month" — $199 is NAD+ injectable, not a weight-loss treatment; the hub page of the same help center says "Start your weight loss journey for just $299/mo". (6) THE MEDICATION LIST ON /contact-us OMITS A PRODUCT IT SELLS. It lists semaglutide injection, semaglutide oral tablets and tirzepatide injection — leaving out tirzepatide tablets, which have their own product page and their own published price. (7) NO LEGITSCRIPT CERTIFICATION CONFIRMED. Willow's footer links to a LegitScript keyword SEARCH for startwillow.com rather than to a certificate, and LegitScript's checker returned 403 to direct lookup and requires a reCAPTCHA in-browser (2026-09-16). We do not assert a certification either way — this is a limit of our check, not a finding against Willow. (8) AN FDA WARNING-LETTER HISTORY AT ONE OF ITS NAMED PHARMACIES, NOT AT WILLOW. See the separate box on this page. WHAT WE CHECKED AND FOUND CLEAN: the FDA warning-letter database returns no letter for "Willow Health Services", "Willow Health" or "startwillow", and none for four of the five named pharmacies (searched fda.gov's own datatables-data endpoint directly, exact-phrase, 2026-09-16); BBB has no profile for Willow Health Services or startwillow.com (searched bbb.org's search API directly, 2026-09-16 — a null result, not a failed search); the Trustpilot profile is live and claimed, not suspended or removed. DISCLOSURE ON OUR SIDE: Willow's Katalys program lists a $315 payout, which we have not yet confirmed is paid on the GLP-1 action, so Willow is excluded from every promoted commercial slot on this site until we do. Its rank is computed from evidence only and never from commission.

FDA warning letters against a named fulfillment pharmacy — not against Willow
Willow names its partner pharmacies in its own Terms of Service. One of them holds 2 FDA warning letters, none of which has been closed out. This is a fact about the pharmacy that fills the prescription, not a finding against Willow, and it does not change Willow's score.
Empower Clinic Services, LLC dba Empower Pharmacy — MARCS-CMS 700964, issued 2025-04-02
one of the five compounding pharmacies Willow names in its own Terms of Service (7601 North Sam Houston Parkway West Suite 100, Houston, TX 77064 — the same facility address FDA inspected). Issued by Center for Drug Evaluation and Research (CDER). Subject: Compounding Pharmacy/Adulterated Drug Products. Posted 2025-04-29. No closeout letter posted.
Following an inspection from September 24 to October 4, 2024, FDA states that drug products intended or expected to be sterile were "prepared, packed, or held under insanitary conditions, whereby they may have become contaminated with filth or rendered injurious to health," making them adulterated under FDCA 501(a)(2)(A). Three specific observations: routine environmental monitoring did not sample within the critical area where aseptic processing occurs; media fills were not performed under the most challenging or stressful conditions, so there is "a lack of assurance that your firm can aseptically produce drug products"; and the stopper sorting bowl, supply hopper and insertion station contacting stoppers used for injectable products were not sterilized. FDA found some corrective actions adequate but could not fully evaluate others for lack of supporting documentation.

same pharmacy, earlier letter; this one cites a different facility (5980 West Sam Houston Parkway North, Houston) than the address Willow publishes. Issued by Office of Pharmaceutical Quality Operations, Division II. Subject: Compounding Pharmacy/Adulterated Drug Products. Posted 2021-10-26. No closeout letter posted.
Earlier letter to the same company on the same subject, at a different Houston facility. Recorded here because it establishes that the 2025 letter is the second on adulterated compounded drug products at this pharmacy, not an isolated finding.

What the research says
Dr. Daniel J. Drucker (Lunenfeld-Tanenbaum Research Institute, University of Toronto — co-discoverer of GLP-1 biology) reviewed the expanding evidence base for GLP-1 medicines beyond weight loss, including cardiovascular and kidney-disease benefit, alongside open questions on long-term safety that still require more data.

How Willow works
- 1. Online intake. Complete a medical questionnaire and eligibility check (often BMI-based) covering your health history.
- 2. Clinician review. A licensed clinician reviews your information and, if appropriate, prescribes semaglutide or tirzepatide with a dose-titration plan.
- 3. Delivery & monitoring. Your medication ships discreetly to your door, with check-ins and dose adjustments along the way.
