Comparison
The two registered weight-management and diabetes medicines people most often compare. Both are lawful prescription products — the differences are mechanism, evidence and access.
Both are genuine, well-evidenced prescription medicines — a different category to the unapproved peptides elsewhere on this site. Which is appropriate (if any) is a clinical decision for your prescriber.
The shared caution is around unapproved “compounded” or online versions, which do not carry the same quality assurance as the registered products.
Weight studies have generally shown larger effects for tirzepatide, but “better” depends on the individual, the indication, tolerability and availability. That is a clinical judgement, not something to decide from a comparison table.
