Ozempic vs Wegovy vs compounded semaglutide: what's actually different

Three products, one molecule, a lot of confusion. Ozempic, Wegovy, and compounded semaglutide are all built around semaglutide, but they are not interchangeable in the eyes of the FDA, your prescriber, or your wallet. Here's what actually separates them.

Same molecule, different labels

Ozempic and Wegovy are both FDA-approved semaglutide products made by the same manufacturer, but they're approved for different things: Ozempic for type 2 diabetes, Wegovy for chronic weight management in adults who meet the label's BMI criteria¹. They're also formulated and dosed somewhat differently to fit their respective approved indications and maximum doses. Off-label prescribing — a doctor prescribing Ozempic for weight loss in someone without diabetes, for instance — does happen in medicine generally, but it means you're outside the specific population the drug was studied and approved for at that dose.

Where compounded semaglutide fits

Compounded semaglutide is a third category entirely: a version of the same active ingredient prepared by a licensed compounding pharmacy rather than sold as either FDA-approved brand³. It is not FDA-approved as a product — the agency does not review each compounded formulation for safety and efficacy the way it does Ozempic or Wegovy³. That doesn't make it inherently unsafe; compounding is a legitimate, longstanding part of pharmacy. It does mean the quality floor depends entirely on the specific pharmacy behind it, which is why vetting matters so much more here than with a brand product. The full checklist for that is in is compounded semaglutide legit?.

Why the compounded market exists at this scale

For a long stretch, semaglutide spent time on the FDA's official drug-shortage list, and shortage status gives compounding pharmacies more latitude to prepare copies of a drug in short supply⁴. That regulatory window is a major reason the cash-pay compounded semaglutide market grew as fast as it did. As brand supply has recovered, that latitude has narrowed — the full story is in GLP-1 shortages and supply, and the mechanics of why compounded pricing looks the way it does are in compounded vs brand-name GLP-1, explained.

The price and access trade-off

Brand-name Ozempic and Wegovy carry high list prices and, for the weight-loss indication specifically, inconsistent insurance coverage — see our insurance coverage guide for how that actually works. Compounded semaglutide is typically priced far lower out of pocket because it isn't tied to a manufacturer list price, which is the whole reason cash-pay telehealth desks built a business around it. Our full cost breakdown, across all three paths, is in how much does semaglutide cost.

Same underlying safety profile

Whichever version you're on, the active molecule carries the same FDA-described boxed warning about thyroid C-cell tumors seen in rodent studies and the same contraindication for anyone with a personal or family history of medullary thyroid carcinoma or MEN 2¹. A compounding pharmacy doesn't change the underlying pharmacology — it changes who's making the product and how tightly that process is regulated. Whether telehealth prescribing of any of these three products is even available in your state is its own separate question, covered in is GLP-1 telehealth legal in my state?.

Which one should you actually use?

That's a clinical decision between you and a prescriber, not something to self-select based on price alone.
