Research Overview
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.
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.
