Research Overview
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.
Cotadutide
Phase 2 studies reported dose-dependent weight loss and favorable changes in glycemic and liver-related markers. It is one of the most cited synthetic dual-agonist peptides for obesity research.
