Research Overview
BDNF
BDNF is repeatedly associated with learning, long-term potentiation, and recovery from neurologic injury in preclinical literature. Direct protein delivery is difficult, so most studies focus on pathways that raise endogenous BDNF or on localized experimental administration.
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.
