Research Overview
NPY
NPY has been shown in animal studies to protect neurons from excitotoxic injury and to dampen stress-linked cognitive impairment. It is often discussed as a counterbalance to overactive glutamatergic and stress pathways in the brain.
Davunetide
Preclinical work showed davunetide can protect neurons, preserve synaptic structure, and improve performance in memory tasks. Human trials largely focused on neurodegenerative disease outcomes rather than stand-alone nootropic use, but the literature supports CNS activity.
