About Orforglipron — Research Context
Orforglipron is Eli Lilly’s oral non-peptide GLP-1R agonist — the first small molecule activating GLP-1R via an allosteric transmembrane site, enabling once-daily oral administration without fasting requirements. Phase 3 ATTAIN trials confirmed significant weight reduction and cardiovascular risk reduction; FDA approved for T2D in 2025. As one of the most-watched compounds in metabolic research, Orforglipron supply consistency and purity are critical for reproducible research outcomes.
