Research Overview
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.
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.
