Research Overview

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.

Endomorphin-1

Endomorphin-1 is a key research peptide in studies of endogenous mu-opioid signaling and spinal analgesia. Like other peptide analgesics, its main translational hurdles are enzymatic instability, limited oral bioavailability, and delivery across barriers.
