Is Compounded semaglutide or Ozempic better for weight loss?

Only Ozempic has a trial figure recorded here: 6.4% average weight loss, worked out from the kilograms on its label. Compounded semaglutide has none on this site — a compounded preparation has no trial of its own, so the two cannot be compared on effect and this page does not pick one on it.

Can you switch between Compounded semaglutide and Ozempic?

They are the same molecule, semaglutide, but Compounded semaglutide is a compounded preparation and Ozempic the approved product, so switching changes the product even though the molecule stays the same.

Compounded semaglutide is $129–$349 a month all-in, the range its sellers here charge, oldest read 2026-09-13; Ozempic (semaglutide, diabetes label) is $199–$499, read from its own page on 2026-09-22.

Flags recorded here: Compounded semaglutide — not FDA approved, supply risk. Ozempic (semaglutide, diabetes label) is an FDA-approved product and Compounded semaglutide is a compounded copy made under the pharmacy-compounding exemption, which is a legal status rather than a quality claim. The published formula scores them 1.9 and 5.1 out of 10, arithmetic over the same stored fields rather than an editor's preference. Cost here is scored on what a patient pays once titrated, never on the entry price, because an introductory rate covers the months before anybody has reached the dose they stay on.

Off-label for weightBoxed warning

Compounded semaglutide

Pros

+$129–$349 a month puts semaglutide within reach for people who would otherwise take nothing; branded semaglutide costs $299 a month for the Wegovy pill and $349 for the pens once past the starting doses.[1]
+Often shipped in vials with flexible dosing, so a provider can titrate in smaller steps than the fixed branded pen doses allow.[1]

Cons

−Not FDA approved. The agency does not review compounded drugs for safety, efficacy or manufacturing quality — potency and sterility depend entirely on the individual pharmacy.[1]
−The FDA declared the semaglutide shortage resolved, which removed the legal basis for mass compounding of copies. Providers now rely on 'personalized dose' arguments that Novo Nordisk is actively litigating.[2]
−Supply can stop mid-titration. A court order or state action against your compounder ends your prescription with no notice — in March 2025 Washington's Pharmacy Commission issued a limited stop-service order against Aequita, the Kirkland pharmacy that then supplied Mochi Health.[3]
−Some products are semaglutide salts (sodium or acetate) rather than the base molecule studied in trials. The FDA has warned these are different substances.[1]

Ozempic (semaglutide, diabetes label)

Pros

+New self-pay patients pay $199 for the first two monthly fills on TrumpRx, through 31 December 2026, then $349 a month at 0.25 to 1 mg.[2]
+Identical active molecule to Wegovy.[2]
+If you have type 2 diabetes, this is the on-label product and the one insurance is most likely to cover.[2]

Cons

−Using it for weight loss without diabetes is off-label. Insurers deny it on that basis and prescribers vary in willingness.[2]
−Its top dose is 2 mg, against 2.4 mg for standard Wegovy and 7.2 mg for Wegovy HD; the Ozempic label reports no weight-loss percentage to set beside Wegovy's.[5]
−Prescribing it off-label for weight competes with diabetes patients for supply — a recurring shortage driver.[2]
