Step 2: Doctor Review – A licensed U.S. physician reviews your information and, if appropriate, prescribes a personalized GLP-1 plan.

Step 3: Medication Shipped – Your compounded medication is prepared by a licensed U.S. pharmacy and shipped for free, usually within 5 business days.

Step 4: Ongoing Support – You get unlimited messaging with your doctor, free follow-ups, and access to digital tools and a peer community.

#4 - Medical Support and Safety

Medical Support:

Willow states that its care is led by board-certified U.S. physicians, including its Chief Medical Officer, Dr. Michael Green. Their website states they offer same-day prescription, if clinically appropriate, unlimited messaging with the assigned doctor, free follow-up consultations, and access to educational tools and a peer community. According to Willow, these features are designed to provide ongoing, personalized medical support throughout the treatment.

Safety:

Willow explains that its medications are custom-compounded by licensed U.S. pharmacies and are not FDA-approved or clinically tested. The company advises using them only under physician supervision. Willow notes that common side effects – such as nausea, vomiting, and constipation – are generally mild and manageable, with doctors available to adjust dosages or prescribe anti-nausea medication if needed. Tapering off treatment is recommended to help maintain results safely.
