A comparison of single-target GLP-1 agonism versus dual GIP/GLP-1 receptor engagement. Both compounds are studied for metabolic pathway modulation but differ fundamentally in receptor pharmacology.
| Criterion | ||
|---|---|---|

Research Assessment
Semaglutide is the established benchmark for GLP-1R-specific research. Tirzepatide adds GIP receptor engagement for studies requiring dual incretin pathway investigation. The choice depends on whether single- or dual-receptor pharmacology is needed for the research model.
