If Ro.co and Start Willow are the two tabs still open, the deciding information is not on either homepage — it is in what happens after the first month.
Choosing between them is really choosing between an approved finished drug and a compounded preparation. Ro.co sits on one side of that line and Start Willow on the other, and no amount of feature comparison makes the distinction go away.
Below, the two programs are set against the things that change the bill — the advertised rate, the rate after the promotion expires, the medication class and the inclusions. Every figure traces back to the provider's own published material, and the missing ones stay missing.
The short answer
- Lowest ongoing rate
- Ro.co — $39/mo against $299/mo, though only one of the two publishes enough to total a full year.
- FDA-approved medication
- Ro.co — FDA-approved Wegovy pill (oral GLP-1) and brand-name GLP-1 injectables — a finished product the FDA has reviewed, rather than a compounded preparation.
- Tirzepatide access
- Start Willow — The only one of the two that publishes a dual GIP/GLP-1 option.
- Easiest to pay for
- Ro.co — Neither publishes financing; both expect the full amount monthly.

What you will have spent by month twelve
The cheapest first month and the cheapest year are frequently different providers. The figures underneath convert both offers into what you will have spent by month six and month twelve.
| Ro.co | Start Willow | |
|---|---|---|
| First month | $39 | $249 |
| Months 2 onward | Not published | $299/mo |
| 6-month total | Not computable | $1,744 |

Price escalation to plan for: Start Willow moves from $249 to $299, a 20% increase. Set a calendar reminder for the month it changes.
The regulatory difference, in plain terms
On Ro.co's side of the line sits FDA-approved Wegovy pill (oral GLP-1) and brand-name GLP-1 injectables — product manufactured under an approved application, with the batch-to-batch consistency that approval requires.
Start Willow supplies compounded semaglutide and compounded tirzepatide — compounded medication prepared by a pharmacy rather than manufactured under an approved application. That is what makes $299/mo possible in the first place, and it is also why the oversight is not the same.
Neither choice is wrong, but they are different risks. Paying $39/mo buys regulatory certainty. Paying less buys access, on terms where the manufacturing oversight is not the same.

Where each program concedes something
On price. Ro.co is the cheaper program at $39/mo against $299/mo. What Ro.co gives up for that is an FDA-approved finished medication costs multiples of a compounded vial; what Start Willow charges for is a delivery guarantee of three days or less and no membership stacked on the medication price.
On clinical contact. Established full-service platform with clinician oversight at Ro.co; direct-pay model that bypasses insurance pre-authorization at Start Willow. Neither is a substitute for in-person care if you have complicating conditions, and both bill you directly rather than your insurer.
On medication. Ro.co covers FDA-approved Wegovy pill (oral GLP-1) and brand-name GLP-1 injectables; Start Willow covers compounded semaglutide and compounded tirzepatide. Only Start Willow publishes a tirzepatide route, which matters if semaglutide underdelivers.
On access. Ro.co advertises online consultation and home delivery; Start Willow advertises fully online, no in-person visits and delivery guaranteed in 3 days or less. Neither publishes its state coverage, so confirm you are eligible before paying for anything.
Evidence and regulatory status
Neither Ro.co nor Start Willow manufactures the molecule it prescribes, and the clinical evidence behind GLP-1 treatment belongs to the drug rather than to any platform selling access to it.
The NIH position is that weight-management medication works alongside changes in eating and activity, not instead of them, per NIH, NIDDK.
Cardiovascular benefit has been demonstrated for semaglutide in a specific population: adults with overweight or obesity and existing cardiovascular disease but no diabetes, per NEJM, SELECT.
Neither platform's marketing changes any of that. It is the same evidence base whichever one takes your card.
Ro.co vs Start Willow: common questions
Is Ro.co cheaper than Start Willow?
Yes, on the ongoing rate. Ro.co runs $39/mo once promotional pricing ends, against $299/mo at Start Willow — a difference of 7.7x. Compare the first-month offers separately, because both providers discount entry differently from the rate you will actually be paying by month three.
Does Ro.co or Start Willow offer tirzepatide?
Start Willow does. Ro.co publishes FDA-approved Wegovy pill (oral GLP-1) and brand-name GLP-1 injectables only, so moving to tirzepatide would mean moving provider — a new intake, a new price, and the loss of any rate you had locked in.
Can I switch from Ro.co to Start Willow later?
You can, and people do — usually when an introductory price expires. Budget for a repeat intake and a short overlap in supply, and confirm what happens to any unused portion of a multi-month plan before you cancel it.
Do Ro.co and Start Willow prescribe the same medication?
No. Ro.co dispenses brand-name, FDA-approved finished medication; Start Willow dispenses compounded medication prepared by a pharmacy rather than manufactured under an approved application. That is a regulatory difference rather than a branding one, and it is the main reason the two prices are not directly comparable.
Are Ro.co and Start Willow legitimate?
Both are licensed telehealth platforms that route a prescription through a clinician review before anything is dispensed; neither sells medication without one. Ro.co operates on promotional first month, then standard rate with pricing partly published, Start Willow on promotional first month, then standard rate, published upfront. The meaningful due diligence is on the medication category and the terms, not on whether the platforms are real.
The verdict
Ro.co is the cheaper of the two to run at $39/mo, but a full-year total is only computable for one side of this comparison, so treat that as a directional finding rather than a settled one.
Start Willow's case is a delivery guarantee of three days or less and no membership stacked on the medication price; its cost: at $299 ongoing it is among the most expensive compounded programs here.
Neither choice is irreversible. Start with the program whose weaknesses you can tolerate, and reassess at month three when you know how you respond to the medication.
