Research Overview
Exendin-4
Exendin-4 helped establish GLP-1 receptor biology in diabetes and remains a classic beta-cell protective peptide. Preclinical studies show reduced beta-cell apoptosis, improved insulin content, and better islet function under metabolic stress.
Insulin Aspart
Research consistently shows faster onset and earlier peak action than regular human insulin. It is commonly studied for meal-time glycemic control and pump-based insulin delivery.
