Research Overview
Insulin Glargine
Clinical and translational studies support its use as a basal comparator because of prolonged absorption and stable glycemic control. It is heavily used in basal-bolus regimen research and insulin-delivery optimization studies.
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.
