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

Strong: multiple large phase 3 RCTs (SUSTAIN, STEP programmes) and regulatory approval.
