Research Overview
NGF
NGF is one of the most established growth factors in neurobiology and has been investigated for both central and peripheral neuronal repair. Its strongest cognitive relevance comes from supporting basal forebrain cholinergic neurons and downstream memory circuitry.
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.
