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.
L-692,429
L-692,429 was important in early GH secretagogue research because it showed that nonpeptide molecules could trigger robust GH release. It remains a classic tool compound for studying receptor-mediated GH pulsatility and appetite signaling.
