This is the question that gets asked more than any other, and the answer is shorter than people expect: they are the same molecule, made by the same company. Everything that differs about them is regulatory or commercial rather than chemical.

Same drug, different label

Ozempic is semaglutide approved for type 2 diabetes — and, for some patients, to lower cardiovascular risk — with doses running up to about 2 mg a week.

Wegovy is the same semaglutide approved for chronic weight management, with a higher ceiling of up to 2.4 mg a week. Same substance, different indication, different maximum.

So which is "for weight loss"?

Wegovy is the one approved for it, which is why it is dosed higher and prescribed for it. Ozempic is frequently used off-label toward the same end but is, on paper, a diabetes drug.

In practice, coverage and supply decide more than anything on this page does. Which brand you end up holding is very often a question your insurer answered before your prescriber did.

Where Rybelsus fits

Rybelsus is also semaglutide, taken as a daily tablet rather than a weekly injection, and approved for type 2 diabetes.

Tirzepatide — Mounjaro and Zepbound — is a genuinely different molecule and a separate comparison.

What matters for you

Whichever box you were handed, the work is identical: titrate at the pace your prescriber sets, protect the muscle with protein, manage the side effects, and keep a record of how you responded rather than how the internet did.

Lean Protocol does not care which label is on the vial. Educational, not medical advice — your prescriber chooses your medication, dose, and indication.
