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.

Tianeptine sodium

Clinical studies support tianeptine as an antidepressant with a distinctive glutamatergic and neuroplasticity-related profile. Some evidence suggests cognitive benefits in mood-impaired populations, likely secondary to improved stress handling and affect.
