|---|---|---|

| Class | GLP-1 agonist | GLP-1 agonist |
| Summary | A once-daily GLP-1 drug with large RCT support for glucose control, weight loss, and lower cardiovascular risk in high-risk type 2 diabetes. | An investigational triple-hormone agonist with striking weight-loss data in trials, but not yet FDA-approved and with no peer-reviewed Phase 3 results. |

Liraglutide
Liraglutide is one of the better-studied metabolic drugs of the last fifteen years, and the direct predecessor to semaglutide.

Retatrutide
Retatrutide (Lilly code LY3437943) is an investigational injectable drug for obesity and type 2 diabetes. It has produced some of the largest weight-loss figures seen in trials so far, but as of June 2026 it is not approved anywhere and its pivotal Phase 3 data have not yet been peer-reviewed.
