Quick Verdict
Editorial Take
Best Overall: Neither, and the choice is not really about which is better. Ro prescribes FDA-approved branded medications and helps you use insurance; Willow prescribes compounded formulations cash-pay, including needle-free tablets Ro does not match across both molecules. These are different products, not two versions of the same one.
Best for Budget: Depends entirely on your insurance. If your plan covers Wegovy or Zepbound, Ro plus its insurance concierge is likely cheapest by a wide margin. If you have no coverage, compounded programmes like Willow are usually the lower cash-pay route.
Best for Fast Approval: Willow. It advertises same-day doctor approval and free 2-day shipping, while Ro tells you whether you are eligible within 2 days and then works through insurance, which adds time before medication ships.

- ✗The insurance step adds time before medication ships
- ✗No tirzepatide tablet, so the needle-free options are semaglutide or orforglipron only
- ✗Membership fee applies on top of medication cost
Honest Tradeoffs
Pricing
Head-to-head price tables mislead here: Ro can be far cheaper than any compounded programme if insurance covers Wegovy or Zepbound, and pricier if it doesn't. Willow's cash-pay cost is fixed and knowable at the assessment regardless of plan. Check your coverage first, it decides which is cheaper.
Medication Types
The real difference: Ro dispenses FDA-approved Wegovy, Zepbound, Ozempic and the newer Foundayo (orforglipron). Willow dispenses compounded semaglutide and tirzepatide, which Willow states are not FDA approved or trial-evaluated for safety, efficacy or therapeutic equivalence, but counters with format, the only one of the two offering a daily needle-free tirzepatide tablet.
Doctor Involvement
Both are genuinely clinician-led. Willow offers same-day doctor review, unlimited care access, messaging and free follow-ups. Ro's Ro Body membership includes unlimited provider messaging, titration support and 1:1 coaching under a named board-certified obesity medicine physician. Ro offers more structured coaching; Willow offers faster access.
Delivery Speed
Willow is faster to start: same-day approval and free 2-day shipping. Ro determines eligibility within 2 days, then works through insurance before dispensing, a slower path by design since that step is what can make the medication far cheaper.
Subscription Model
Willow is a monthly cash-pay prescription service with FSA/HSA eligibility. Ro's membership bundles coaching, messaging and the insurance concierge with medication access, a support programme versus a medication supply.
Pricing Breakdown
| Aspect | Willow | Ro |
|---|---|---|
| Payment model | Cash-pay only | Insurance or cash-pay |
| Insurance help | None; no insurance accepted | Dedicated insurance concierge |
| FSA / HSA | Eligible | Varies by plan and product |
| Entry cost | Confirm at the free assessment | $39 to get started |
| Cash-pay discounts | Confirm at assessment | FDA-approved GLP-1s at half the usual price; Prepay & Save on Wegovy |
| Shipping cost | Free, 2-day | Included with membership |
| Cost predictability | Fixed and knowable before you start | Depends on coverage; not quotable up front |
What You Actually Pay Over 12 Months
Advertised starting prices are the least useful number in this comparison, so below is what each provider costs across a realistic course of treatment rather than on day one. Pricing verified July 30, 2026; confirm the final figure at enrollment, as offers change.
| Willow | Ro | |
|---|---|---|
| First month | Cash-pay; varies by treatment format, confirm at the free assessment | $39 to get started |
| 6-month total | Six times the quoted monthly rate; fixed, since no insurance variable applies | Not computable in advance; ongoing cost is half the usual price of the FDA-approved medication, then adjusted by your insurance coverage |
| 12-month total | Twelve times the quoted monthly rate; fixed for the same reason | Not computable in advance, for the same reason |
| Price includes | Medication, same-day doctor review, free 2-day discreet shipping, doctor messaging, free follow-ups and Care Team support | Ro Body membership: FDA-approved medication access, insurance concierge, unlimited provider messaging, titration and side-effect support, weight and dose tracking, 1:1 health coaching |
| What can raise it | Price differs across the four formats, so switching between tablets and injections can change the rate | Losing coverage moves you to cash-pay; Prepay & Save reduces cash-pay Wegovy pricing |
No single cheaper-or-not answer exists here. Willow's cash-pay cost is fixed and knowable upfront. Ro's is genuinely unknowable until you run its insurance check, because coverage for Wegovy or Zepbound can cut cost far below any compounded programme. If your plan covers a branded GLP-1, Ro is likely cheaper and FDA-approved, the stronger case on both counts. If not, you're comparing two cash-pay prices, and Willow's fixed rate and needle-free tablets become the argument.
Medication Comparison
Semaglutide
Willow offers compounded semaglutide as a weekly injection or daily needle-free tablet. Ro offers FDA-approved semaglutide as the Wegovy pen (insurance or cash-pay), the Wegovy pill (cash-pay only) and Ozempic (FDA approved for type 2 diabetes, prescribed off-label for weight loss).
Tirzepatide
Willow offers compounded tirzepatide as a weekly injection or daily needle-free tablet. Ro offers FDA-approved tirzepatide as the Zepbound pen (insurance or cash-pay) and KwikPen (cash-pay only), with no pill option, so a needle-free dual-agonist is Willow-only.
Which Provider Offers What
Ro has the broader medication range, adding orforglipron (Foundayo), which Willow doesn't carry. Willow has the broader format range, the only one with tablets for both semaglutide and tirzepatide. Want FDA-approved, choose Ro; want needle-free tirzepatide, choose Willow.
Results Expectations
Safety Considerations
Side Effects
Both carry the GLP-1 side-effect profile: nausea, vomiting, upset stomach, stomach pain, constipation and diarrhoea. Both carry a thyroid C-cell tumour warning and should not be used with a personal or family history of MTC or MEN 2. Review full safety information with your clinician before starting.
Doctor Supervision
Both require U.S. licensed clinician review before dispensing. Willow provides doctor messaging, free follow-ups and unlimited care access. Ro provides unlimited provider messaging, side-effect management, titration support and 1:1 coaching within the Ro Body membership.
Prescription Requirement
Both are prescription-only after an online consultation. The critical distinction is regulatory: Ro dispenses FDA-approved medications, while Willow's compounded products are, in Willow's own words, not approved or evaluated for safety, effectiveness or quality by the FDA, and are not substitutes for Mounjaro, Zepbound, Wegovy or Ozempic.
How We Evaluated These Providers
We evaluated both providers based on the following criteria:
- ✓Regulatory status of the medications each provider dispenses, FDA-approved against compounded
- ✓The full product range at each, including formats and molecules
- ✓How cost is determined, and whether it can be known before starting
- ✓Insurance handling and the presence of coverage support
- ✓Speed from assessment to medication in hand
- ✓State availability, which excludes Willow entirely for some patients
- ✓Included clinical support: messaging, follow-ups, coaching and titration
Final Verdict
Editorial Take
Best for Budget Users
Check your insurance before deciding, because that answer flips the result. With coverage for Wegovy or Zepbound, Ro and its insurance concierge will almost certainly be cheaper. Without coverage, a cash-pay compounded programme like Willow is usually the lower-cost route.
Best for Fast Results
Willow starts faster, with same-day approval and 2-day shipping against Ro's 2-day eligibility answer followed by an insurance step. On the pace of weight loss itself, only Ro's FDA-approved medications carry trial data behind them; Willow's compounded formulations do not.
Best for Doctor Supervision
Ro, on structure. Both are clinician-led, but Ro includes 1:1 health coaching, titration support and named board-certified obesity medicine leadership. Willow offers faster and more open-ended access, with unlimited care and a peer community.
Best Premium Experience
Ro. The Ro Body membership bundles FDA-approved medication access, an insurance concierge, coaching and dose logging into one programme. Willow is the leaner, faster, cash-pay option that gives you formats Ro cannot match.
