Overview
A GLP-1 receptor agonist approved for type 2 diabetes and, at higher doses, chronic weight management. It is the best-evidenced peptide in this library, backed by large randomised trials.
Mechanism
Mimics glucagon-like peptide-1, enhancing glucose-dependent insulin secretion, slowing gastric emptying and reducing appetite via central pathways.
Evidence
