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.
Efinopegdutide
Human trials have shown meaningful weight loss and improvements in hepatic steatosis biomarkers. It remains a research compound with ongoing development in metabolic disease.
