Is Willow legit?
Yes — Willow is a real, operating US telehealth company, not a fake storefront. That is usually what the question means, and it is the easy part.
The harder part is what it sells you. It supplies compounded medication — prepared by a compounding pharmacy, not an FDA-approved product. We have 3 sourced regulatory or legal actions on record against it, listed below with links to the primary documents.

What it actually supplies
Supplies compounded semaglutide or tirzepatide — medication prepared by a compounding pharmacy, not an FDA-approved product. Cheaper, legal, and the category the FDA has been issuing warning letters about.
Named on its own site: compounded semaglutide injection, compounded semaglutide tablet, compounded tirzepatide injection, compounded tirzepatide tablet.
What regulators and courts have said
Each of these links to its source, and each says which kind of source that is. We publish what the record says and nothing beyond it — an action against a company is not proof that a particular customer was harmed.
December 2025
The National Advertising Division, on a challenge by Novo Nordisk, recommended on 4 December 2025 that Willow Health Services discontinue or modify health claims for its compounded semaglutide products. Willow declined to provide a compliance statement, and NAD referred the matter to regulatory authorities and to the platforms carrying the advertising.
July 2026
Reopened NAD matter closed after Willow Health Services voluntarily discontinued claims that its compounded semaglutide was proven to support weight loss, delivered results comparable to FDA-approved semaglutide, and produced effective weight loss without diet or exercise.
February 2026
Eli Lilly sued Willow Health Services, Inc. in the Central District of California on 23 April 2025 (No. 2:25-cv-03570) over compounded tirzepatide. The case was dismissed with prejudice on 3 February 2026 for failure to establish Lanham Act standing — the court held the prescribing physician, not Willow's advertising, was the proximate cause of any lost sales — with no ruling on whether the marketing was misleading. Lilly has appealed to the Ninth Circuit (No. 26-1317).
Other signals on file
Not regulatory or legal actions, and not counted as any. These are recorded because they are sourced and worth knowing — complaint volumes, third-party reports, disputes between companies.
BBB profile for 'Start Willow' (Austin TX) rating D, not accredited, with 5 complaints of which 1 unanswered.
Third-party review reports Willow uses three compounding pharmacies (Red Rock Home Pharmacy, Epiq Pharmacy, The Pharmacy Hub) and that cancellation language conflicts between the FAQ and the informed-consent document.
Worth knowing
EDITOR MUST CHECK: the report could not documentarily confirm that startwillow.com is operated by 'Willow Health Services, Inc.', the entity named in the Lilly suit and both NAD decisions; verify before attributing those matters to the consumer brand. Site states plainly that its products are compounded and not FDA approved. Refund policy per the official FAQ: cancel at least 2 business days before the next charge for a full refund in 5-10 business days if the pharmacy has not processed the order.
