Willow GLP-1 is an online, doctor-led weight-loss program for adults who may qualify for semaglutide or tirzepatide after a clinician reviews their health history. Willow says its plans start at $299 per month, include medication, physician messaging, support and shipping, and offer both weekly injections and daily dissolving tablets.

Willow’s official site is startwillow.com. Its program is built around an online assessment, a physician review and medication delivery when the clinician decides a prescription is appropriate.
Is Willow GLP-1 legit?
Yes. Willow is a telehealth platform that connects adults with independent, licensed physicians and pharmacy partners. The company says a physician reviews your assessment, health history and goals before writing a prescription, if appropriate. It also says you can message your physician through the patient portal and usually keep the same physician during care.
For a community buyer, the useful point is that Willow is not itself the doctor’s office or the pharmacy. Willow’s terms say it facilitates the connection to physicians and pharmacies. That makes the details of your prescribed medicine, dose, pharmacy and follow-up plan worth confirming before you pay.
What does Willow offer?
Willow markets compounded semaglutide and tirzepatide in injectable and daily dissolving-tablet forms. The maker describes semaglutide as working on GLP-1 receptors involved in appetite and digestion. It describes tirzepatide as acting on GLP-1 and GIP receptors.
Willow says its program includes a same-day assessment, ongoing physician access, 24/7 care-team support and free shipping. It serves adults age 18 and older in the states listed on its FAQ page. It says people who are pregnant or breastfeeding, people with certain conditions, and people with diabetes are not eligible through its program.
Is Willow semaglutide FDA approved?
No. Willow says its semaglutide and tirzepatide products may be compounded medications. Compounded medications are made for an individual prescription and are not reviewed or approved by the FDA for safety, effectiveness or quality in the same way as FDA-approved drugs. The FDA is the place to ask about the difference between a compounded medicine and an FDA-approved medicine.
That difference matters if you have seen ads using familiar drug names. Ask the prescribing clinician which exact medicine and form is being offered, whether it is compounded, and which pharmacy will fill it.
How much does Willow cost?
Prices were shown as of October 7, 2026; check the checkout for today’s price. Willow says its monthly program starts at $299. The company says medication cost can vary by dosage and prescription. It does not publish a separate tirzepatide price or a dose-by-dose price list in the supplied program information.
| Cost question | What Willow says |
|---|---|
| Starting monthly price | $299 per month |
| What is included | Medical evaluation, treatment plan, physician access, care-team support and shipping |
| Tirzepatide cost | Not published; medication costs vary by dosage and prescription |
| Insurance | Not required |
| HSA/FSA | Accepted at checkout |
| Extra fees | Willow says there are no hidden fees |
Why can a GLP-1 program feel expensive? You are paying for more than the medication: Willow says the monthly amount also covers the clinical review, ongoing physician access, support and delivery. Ask for the total monthly charge at your expected dose before enrollment, especially if you are considering tirzepatide.
What side effects should you know about?
Willow lists nausea, vomiting, diarrhea, constipation, abdominal pain, decreased appetite and indigestion as common possible side effects of semaglutide and tirzepatide. Willow says to contact a healthcare professional if symptoms persist or get worse.
| Topic | What to discuss before starting |
|---|---|
| Current medicines | Bring every prescription, over-the-counter medicine, vitamin and supplement. Ask the clinician whether any need special timing or monitoring. |
| Past health history | Share conditions, prior reactions to medicines, pregnancy or breastfeeding status, and past weight-management care. |
| Digestive symptoms | Ask what symptoms merit a message to the care team and how the dose plan may be handled. |
| Unexpected weight change | Ask your primary care clinician about it. Cleveland Clinic notes that unintentional loss of 10 pounds or 5% of body weight in six to 12 months deserves medical attention. |

Can you take a GLP-1 for only three months?
Willow says its program renews automatically each month. It also says you can cancel by messaging the Patient Care Team. To avoid the next charge, it says to send the request at least two business days before the next processing date.
Willow says people who stop semaglutide or tirzepatide may notice increased appetite and weight gain, and that its physician can help decide whether to continue, lower a dose or transition off medication. A three-month plan is therefore a question to settle with the prescriber before you start, not after the renewal date approaches.
How long does it take to lose 20 pounds?
There is no single timeline for losing 20 pounds. Willow’s homepage includes customer stories, but those are individual experiences, not a promise of a particular result. Your starting weight, dose plan, food intake, activity, sleep, other medicines and health history can all shape what happens over time.
A better first question for your clinician is: “What result and timeline are realistic for me, and when will we reassess?” If you feel stuck before starting medication, a primary care conversation can also help sort through the bigger picture. A PubMed-indexed review on difficulty losing weight describes active clinician involvement as useful when expected progress does not occur.
Will semaglutide reduce belly fat or kick-start weight loss?
Willow presents GLP-1 care as one option within a personalized plan, not as a body-area treatment. You cannot choose where your body changes first. Use the assessment to describe what has made weight management hard for you: hunger, schedule, mobility, sleep, caregiving demands, stress, past diets or medicine changes.
Be careful with catchy plans such as “30/30/30,” a “Japanese trick,” or claims that your body is simply holding on to weight. These phrases do not replace an individual assessment. If you want a low-pressure way to compare a non-prescription weight-management product with a telehealth medication program, see our LipoJaro guide and bring your questions to a clinician.
What happens after you sign up?
Willow says you complete a short online assessment and submit your health history. A licensed U.S. physician reviews it and may create a treatment plan. If medication is prescribed, Willow says pharmacy processing takes two to four business days, followed by home delivery that typically takes two to three days.
Willow says its shipping is free and discreet. It says to contact its Patient Care Team if a package is lost or delayed. Support is available through the website chat feature or at support@startwillow.com.
