Medications

continuous glucose monitoring

Pros

✓A genuinely different approach: a continuous glucose monitor plus an app that tells you how your own body responds to specific foods, rather than a prescription subscription
✓Published plan pricing: $127/month on the longest plan, $150/month on the mid plan and $225/month on the shortest, each discounted from a higher list price
✓Two CGM sensors per month are included in every plan
✓HSA/FSA eligible, which matters at these prices
✓Registered dietitian support is included, with in-app chat and the option of a face-to-face session
✓A 30-day results guarantee: if you do not learn something new about how your body loses weight, a senior Signos coach audits your data free, described as a $250 value
✓One membership covers the sensors, the app, the coaching and the behaviour-change programme instead of stacking separate subscriptions
✓It pairs sensibly with a GLP-1 rather than competing with one, and the company states medication costs are included in the Signos programme where applicable
✓Stress and sleep tracking are built in alongside glucose

Cons

✗This is not a GLP-1 prescribing service in the way the rest of this site is. If you came here for a semaglutide prescription, Signos is a different kind of product
✗The cheapest per-month rate requires the longest commitment, and six-month plans ship in three-month bundles
✗CGM-guided eating for weight loss in people without diabetes has far weaker evidence behind it than GLP-1 medication
✗HSA/FSA eligibility is qualified - "Possibly, but it depends on your HSA/FSA provider" - and Signos states it is not responsible for reimbursement, with the cancellation policy still applying if your provider refuses
✗The results guarantee pays out in a free data audit, not money back
✗Outcome claims reflect individual Signos patient experiences rather than published clinical studies, which the company discloses
✗Not suitable if you are on insulin without speaking to your own clinician first, which the signup flow asks you to confirm

Medications

semaglutidetirzepatide

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
