What does it do?

Helps the mind feel steadier under stress
Supports focus without much stimulation
Can take the edge off anxious mental noise
Is used for calm performance more than raw drive
May improve how stress sits in the body
Does not feel like a sedative for most people

How does it work?

Is built from tuftsin, an immune-related peptide
Can influence GABA and enkephalin pathways tied to calm
Supports neurotransmitter balance involved in anxiety and focus
Acts in the brain more than in muscle or gut
The signal is settling, not switching the brain off
