Noopept

A synthetic dipeptide nootropic developed in Russia and studied for cognitive effects.

What research shows

Everything we verified for noopept is preclinical: cognitive measures in rats, neurotrophic factor expression in rat hippocampus, and mechanistic chemistry of the dipeptide class. Russian clinical use is widely described but we verified no randomized human trial in the literature searched.
