What is Neuropeptide S?

A 20-amino-acid neuropeptide best known for its anxiolytic and arousal-modulating effects in preclinical studies. It is of interest for stress resilience, attention, and mood regulation, but it remains research-only.

Key Benefits & Mechanisms

anxiolysis

stress resilience

attention support

arousal modulation

Research Summary

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.

Arginine Vasopressin

8-Arginine Vasopressin

Arginine vasopressin is a naturally occurring nonapeptide hormone that also has documented CNS effects on memory and social cognition. In research settings it has been studied for its potential to influence consolidation, recall, and arousal-linked learning.
