Research Overview

Insulin Degludec

Studies highlight prolonged action and lower glycemic variability compared with many other basal insulins. It is frequently used in research on ultra-long basal coverage and hypoglycemia reduction.

GLP-1

Native GLP-1 has a very short half-life because of rapid DPP-4 cleavage, so it is mainly used as a mechanistic research peptide. Across animal and cellular studies it reduces beta-cell apoptosis, improves insulin gene expression, and enhances islet resilience.
