Research Overview

Dulaglutide

Dulaglutide has repeatedly shown small-to-moderate reductions in body weight alongside glycemic improvement in large diabetes trials. It is a useful comparator for GLP-1 receptor agonist effects on appetite and weight.

Oxyntomodulin

Human studies showed acute reductions in food intake and modest weight loss, helping establish the GLP-1 and glucagon co-agonism concept. It remains a foundational peptide for obesity and satiety research.
