Research Overview
Arginine Vasopressin
Animal and human studies indicate vasopressin can modulate hippocampal and limbic circuits involved in learning and memory. The effect size is context dependent, and results vary by dose, route, and baseline cognitive state.
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.
