Common questions

Where can I get GLP-1 weight loss treatment in Long Island?

This page lists 5 clinics in and around Long Island that publish GLP-1 or medical weight loss services. Each card shows the services the clinic lists, plus its phone number and website where available.

Do I need a prescription for GLP-1 weight loss medication?

Yes. Semaglutide (Wegovy, Ozempic) and tirzepatide (Zepbound, Mounjaro) are prescription medications. A licensed clinician has to evaluate you first, either in person at a clinic or through telehealth.

How do I make sure I'm losing fat and not muscle on a GLP-1?

Track body composition, not just weight. In the STEP 1 semaglutide trial, roughly 39% of the weight participants lost was lean mass. A DEXA body composition scan before you start and every 8–12 weeks shows fat, lean muscle and visceral fat, so you and your provider can adjust protein, training and dosing.

What's the difference between brand-name and compounded GLP-1s?

Brand-name medications (Wegovy, Zepbound and others) are FDA-approved. Compounded versions are made by pharmacies and are not FDA-approved, so ask any provider which they prescribe, where it is compounded and how the dose is checked.

Can I get GLP-1 treatment online if there's no clinic near me?

Yes. Many states allow telehealth prescribing after a virtual evaluation. DEXASCAN.COM partners with Zyndio, a physician-led telehealth platform, if you'd rather start online and pair it with in-person scans.

How do I claim or update my clinic's listing?
