Both Start Willow and TMates will get a GLP-1 prescription to your door without an in-person visit. The question is what the year after that first shipment looks like.
GLP-1 dosing escalates over the first few months, and providers differ on whether the invoice escalates with it. TMates holds one rate at every dose; Start Willow's price moves from $249 to $299.
This comparison works from what each provider publishes: the entry price, what it becomes at month two, the medication actually dispensed, and what is bundled rather than billed. No number here is inferred; if a provider does not publish it, the table says so.
The short answer
- Lowest 12-month cost
- TMates — $2,388 against $3,538 at Start Willow, on each provider's own best published pricing.
- Most predictable bill
- TMates — Flat rate at every dose, so titration does not change what you are charged.
- Tirzepatide access
- Start Willow — The only one of the two that publishes a dual GIP/GLP-1 option.
- Most support included
- TMates — 24/7 access to U.S.-based doctors, not just messaging.

TMates finishes the year $1,150 cheaper. For some patients the support Start Willow bundles closes that gap; for a patient who only needs the prescription written, it does not.
Price escalation to plan for: Start Willow moves from $249 to $299, a 20% increase. Set a calendar reminder for the month it changes.
What happens to the price as your dose goes up
Semaglutide and tirzepatide are titrated upward over the first months of treatment. Some providers price per milligram in all but name, so the invoice climbs alongside the dose; others hold one rate the whole way.
TMates is in the second group: one flat $199 that survives every titration step, with doctors rather than a message queue behind it. Start Willow is in the first — at $299 ongoing it is among the most expensive compounded programs here — which means the number you compared at signup is not the number you will be paying at month four.
This is the single most common way people end up paying more than they planned for GLP-1 treatment. It is also the easiest to check: ask what the highest maintenance dose costs, not what the starting dose costs.

A closer look at TMates
TMates positions itself on one flat $199 that survives every titration step, with doctors rather than a message queue behind it. $199/month, every dose, no step-up fees
Practically: virtual check-in appointments, medication formulated in U.S. facilities, and a pricing model that is flat rate at every dose.
On the clinical side, 24/7 access to U.S.-based doctors, not just messaging, prescribing compounded semaglutide.
TMates pros
- Flat $199/month at every dose, no step-up fees as dosage escalates
- 24/7 access to U.S.-based doctors, not just messaging support
- Licensed coverage in all 50 states
- Medications formulated in U.S.-based facilities
TMates cons
- Compounded semaglutide only, limited public detail on tirzepatide availability

Who should choose Start Willow, and who should choose TMates
Choose Start Willow if:
- delivery works the way you want it to: delivery guaranteed in 3 days or less
- you want tirzepatide available without changing provider later
- what it leads on is worth paying for in your case: a delivery guarantee of three days or less and no membership stacked on the medication price
- the level of clinical contact suits you: direct-pay model that bypasses insurance pre-authorization
Choose TMates if:
- you want the price you sign up at to survive titration
- the monthly rate is the constraint — $199/mo against $299/mo
- the twelve-month total is what you are optimizing ($2,388 against $3,538)
- you are in a state where GLP-1 telehealth coverage is patchy
The trade-offs, stated plainly
On price. $199/mo against $299/mo. Start Willow is asking you to pay for a delivery guarantee of three days or less and no membership stacked on the medication price; decide whether that is a line item you will use.
On predictability. The pricing structures differ (promotional first month, then standard rate versus flat rate at every dose), and structure, not headline rate, determines the twelve-month bill.
On access. Start Willow advertises fully online, no in-person visits and delivery guaranteed in 3 days or less; TMates advertises virtual check-in appointments and medication formulated in U.S. facilities. Coverage differs too — not published against all 50 states — which decides the question before price does if you are in a restricted state.
On medication. Start Willow covers compounded semaglutide and compounded tirzepatide; TMates covers compounded semaglutide. Only Start Willow publishes a tirzepatide route, which matters if semaglutide underdelivers.
The medication, not the platform
Both platforms sell access to the same drug class, so the clinical record below applies equally to each.
In the STEP 1 trial, weekly semaglutide 2.4 mg produced a mean body-weight change of −14.9% at 68 weeks against −2.4% on placebo, per NEJM, STEP 1.
The STEP 1 extension found participants regained roughly two-thirds of the weight they had lost within a year of stopping semaglutide, per Diabetes, Obesity and Metabolism.
None of that settles which of these two to use. It does mean the drug is doing the work, and you are choosing who supplies it and on what terms.
Start Willow vs TMates: common questions
What happens when Start Willow's promotional price ends?
The rate moves to $299/mo, a 20% increase on the advertised entry price. Budget from that number rather than the headline, because it is the one you will pay for eleven of your first twelve months.
Does the price go up as my dose increases?
At TMates, no — one flat $199 that survives every titration step, with doctors rather than a message queue behind it. At Start Willow, the published structure is promotional first month, then standard rate, moving from $249 to $299. Since GLP-1 doses escalate over the first months, that difference is worth more than most feature comparisons.
How fast can I start with Start Willow compared with TMates?
Start Willow advertises fully online, no in-person visits, with delivery guaranteed in 3 days or less. TMates advertises virtual check-in appointments, with medication formulated in U.S. facilities. Both are subject to clinician review and to whether your state and health history clear, so treat the advertised timeline as a best case rather than a commitment.
Do Start Willow or TMates take insurance?
Both run on a direct-pay basis: you pay the platform and it does not bill your insurer. Neither publishes HSA/FSA acceptance, so budget the full amount as out-of-pocket spending.
Which has more patient reviews, Start Willow or TMates?
TMates, with 21,970 against 6,385. Ratings across this market cluster tightly, so volume is the more useful signal: it indicates how much operational load the platform has already absorbed, not how good the medication is.
The verdict
Strictly on cost, TMates takes it — $2,388 to $3,538 over twelve months.
The case for Start Willow is a delivery guarantee of three days or less and no membership stacked on the medication price. That is worth $96 a month to some patients and nothing at all to others — be honest about which you are.
Whichever you choose, diarise the month the introductory pricing ends and re-run the comparison then. Neither platform will remind you.
