Ozempic® vs Wegovy® vs Zepbound®
General information, not medical advice · A medical provider licensed in your state makes every medical decision
Published
Three brand names, two different medications, and a lot of confusion. Here’s the plain-English map of Ozempic® vs Wegovy® vs Zepbound® — what molecule each contains, what the FDA actually approved each one for, and where compounded options fit — so you can have a clearer conversation with a medical provider.
Two molecules, not three
The first thing to understand is that these three brands come from two different medications:
- Semaglutide — a single GLP-1 receptor agonist. It’s the medication in both Ozempic® and Wegovy®. As the FDA puts it, “Wegovy contains semaglutide, a glucagon-like peptide-1 (GLP-1) receptor agonist.”[3]
- Tirzepatide — a different molecule and the medication in Zepbound®. Per the clinical literature, tirzepatide “is a dual agonist for the glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP) receptors.”[5]
What each brand is FDA-approved for
This is where most of the confusion lives — same molecule, different approved use:
- Ozempic® (semaglutide) — FDA-approved “as an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes mellitus.”[2] It is a diabetes product, not a weight-loss product.
- Wegovy® (semaglutide) — the semaglutide product FDA-approved for chronic weight management in certain adults with obesity or overweight.[3]
- Zepbound® (tirzepatide) — FDA-approved, per its label, “in combination with a reduced-calorie diet and increased physical activity: to reduce excess body weight and maintain weight reduction long term in adults with obesity.”[4]
So if your goal is weight, the FDA-approved-for-weight branded products are Wegovy® and Zepbound® — not Ozempic®.
Where do compounded options fit?
You’ll also see “compounded semaglutide” and “compounded tirzepatide.” These are pharmacy-prepared medications made per-patient by state-licensed compounding pharmacies in FDA-regulated facilities. The regulatory fact to hold onto: “Compounded drugs are not FDA-approved.”[1] A compounded preparation is not a generic version of, or a substitute for, any of the branded products above, and we never present it as equivalent. It’s a separate option a licensed provider may consider.
So which is right for you?
That’s a clinical decision, not something a webpage should answer. The molecule (semaglutide vs tirzepatide), the goal (diabetes vs weight), your medical history, and tolerability all matter, and none of these medications is right for everyone. A medical provider licensed in your state weighs all of it.

Frequently asked questions
What's the difference between Ozempic®, Wegovy®, and Zepbound®?
Ozempic® and Wegovy® both contain semaglutide; Zepbound® contains tirzepatide, a different molecule. Ozempic® is FDA-approved for glycemic control in type 2 diabetes; Wegovy® is FDA-approved for chronic weight management; Zepbound® is FDA-approved for weight reduction. A medical provider determines what, if anything, is appropriate for you.
Is semaglutide the same as tirzepatide?
No. Semaglutide is a single GLP-1 receptor agonist. Tirzepatide is a dual agonist, acting on both GIP and GLP-1 pathways. They are different molecules, and which is appropriate — if either — is a clinical decision.
Where does compounded medication fit in?
Compounded semaglutide and compounded tirzepatide are pharmacy-prepared medications that are not FDA-approved. They are not generics or substitutes for the branded products above, and we never present them as equivalent. A licensed provider decides whether a compounded option is appropriate.
Which one is best for weight?
That's a medical decision, not a marketing one. Wegovy® and Zepbound® are the FDA-approved-for-weight branded products; Ozempic® is a diabetes product.
