Research Overview

Neuropeptide S

Animal studies suggest NPS can reduce anxiety-like behavior while altering wakefulness and alertness through the NPS receptor system. Human cognitive data are very limited, and it has no approved clinical indication.

Dulaglutide

Dulaglutide has repeatedly shown small-to-moderate reductions in body weight alongside glycemic improvement in large diabetes trials. It is a useful comparator for GLP-1 receptor agonist effects on appetite and weight.
