The Three Generations of Incretin Peptide Research The progression from single to dual to triple agonist peptides represents a research trajectory that has played out in roughly ten years: Generation 1 Single GLP-1 Agonists (Semaglutide, Liraglutide, Exenatide) The first incretin peptides to reach broad clinical research were GLP-1 receptor agonists
Research has explored its activity in fatty acid metabolism pathways, mitochondrial function, and cellular energy regulation in controlled laboratory environments
