Medications

Pros
- ✓Flat published pricing: $299/mo for compounded semaglutide as a weekly injection or a daily tablet, and $399/mo for compounded tirzepatide (checked July 26, 2026)
- ✓One fee covers the medical evaluation, the medication, unlimited doctor messaging and free discreet shipping, with no separate consultation charge
- ✓Names its partner pharmacies in its terms - Red Rock Home Pharmacy (Springville, UT), Epiq Pharmacy / Epiq Scripts (Richardson, TX) and The Pharmacy Hub (Miami, FL) - which most compounded GLP-1 sellers do not do
- ✓Publishes a Florida telehealth provider registration number (TPME1718) and names the exact states it is licensed to serve
- ✓The 'compounded drug products are not approved or evaluated for safety, effectiveness, or quality by the FDA' disclaimer sits on the homepage itself, not buried in a footer
- ✓Full refund if you cancel before the prescription is submitted to the pharmacy, processed within 5-10 business days
- ✓Needle-free daily tablets available for both semaglutide and tirzepatide, and the program is HSA/FSA eligible
- ✓Same-day prescription review claimed, with support from a named care team
Cons
- ✗In December 2025 the National Advertising Division found Willow had not substantiated its weight-loss and efficacy claims for compounded semaglutide, Willow declined to comply, and NAD referred it to state attorneys general and ad platforms. That is the most serious independent mark against any provider on this site
- ✗At $299-$399 a month this is one of the more expensive compounded GLP-1 programs; several competitors advertise $149-$199
- ✗The flat rate is not locked. The terms state your subscription fee 'may be increased or decreased if your prescription changes, such as by a dosage increase or frequency of refills', so titrating up can raise your bill
- ✗The site advertises '4.9/5 (2200 + 5 star reviews)' with no source named. Trustpilot, the one public platform we could find, showed 3.8 from 351 reviews on July 26, 2026
- ✗Cancellation must be received two full calendar days before your next shipping date, or the next order ships and bills
- ✗The terms tell you to cancel at startwillow.com/contact/ - that URL returned a 404 when we checked, as did the site's /contact and /help-center pages
- ✗No customer phone number or support email is published anywhere on the public site
- ✗The published terms are dated November 24, 2021, well before the current product line and pricing
- ✗Not available nationwide: Willow's terms limit service to 36 states, and this offer in particular is not available in Alabama, Alaska, Arkansas, Delaware, Kansas, Louisiana, Maine, Massachusetts, Mississippi, New Mexico, North Dakota, Rhode Island, South Dakota, Tennessee, Utah, Vermont, West Virginia or Wyoming
- ✗No insurance billing, and the terms confirm Medicare and Medicaid do not cover the service
