GLP-1 for diabetes vs weight loss: same drug, different labels

The same molecules are sold under different brand names for different indications: semaglutide is Ozempic/Rybelsus (diabetes) and Wegovy (weight); tirzepatide is Mounjaro (diabetes) and Zepbound (weight/OSA). The drug is the same, but the approved indication, dose, and evidence base differ by product.
The full picture
It confuses a lot of people that 'Ozempic' and 'Wegovy' are the same molecule. They are — semaglutide — but approved and dosed for different purposes. The weight-management products were studied and labeled specifically for weight, at doses established in the STEP and SURMOUNT programs.
This matters for compounded shopping because a compounded 'semaglutide' isn't tied to any of these specific approved products or their doses. It's a separate preparation, and the indication and dose are whatever the provider and prescriber decide, not what a brand label specifies.
The oral wrinkle returns here too: Rybelsus (oral semaglutide) is a diabetes product, not a weight-loss one, and a compounded 'oral semaglutide' is neither Rybelsus nor an approved weight product.
