Research Overview
Mazdutide
Clinical programs have shown substantial reductions in body weight and improvements in cardiometabolic risk markers. It is a prominent newer dual agonist in the obesity literature.
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.
