| Retatrutide | Ozempic (semaglutide) | |
|---|---|---|
| Drug class | GLP-1 + GIP + glucagon (triple) | GLP-1 only (single) |
| FDA status (2026) | Phase 3, not approved | Approved (diabetes; Wegovy for weight) |
| Reported weight loss | Up to ~24% (Phase 2) | Up to ~15% (STEP trials, Wegovy) |
| Availability | Clinical trials only | Prescription via licensed provider |
The headline difference is breadth of mechanism. Ozempic/Wegovy act on a single receptor (GLP-1); retatrutide adds GIP and glucagon activity, which appears to drive larger average weight loss in early studies. The trade-off is maturity and access: semaglutide is approved and widely available, while retatrutide remains investigational.

Frequently asked questions
Is retatrutide stronger than Ozempic?
Early trials suggest greater average weight loss with retatrutide, but it is unapproved and far less studied. Ozempic/Wegovy (semaglutide) is approved with an established safety record.
Can I switch from Ozempic to retatrutide?
Not through standard prescribing, because retatrutide isn’t approved. Any change should be guided by a clinician.
