Nootropics overview

A growing family of neuro-active research peptides, from the Russian nootropics Semax and Selank through Noopept, Dihexa, Cerebrolysin, DSIP and more, studied for cognition, stress resilience, mood and sleep. This section covers what the class is, what the literature looks at, and how each compound sits in our catalogue.

Several of the compounds gathered here are sometimes called the “Russian nootropic peptides”: short, synthetic sequences derived from naturally occurring fragments and studied in research models for effects on memory, focus, anxiety and sleep regulation. Others, such as Dihexa, PE-22-28 and Cerebrolysin, come from different research lineages but share the same broad focus on the central nervous system. Everything documented here is supplied strictly for laboratory research use only, not for human or veterinary use.

What nootropic peptides are

Nootropic peptides are short amino-acid sequences investigated for their influence on the central nervous system, the pathways behind cognition, focus, stress resilience and related neuro signalling. Unlike the metabolic or repair peptides covered elsewhere in these docs, this class is studied primarily for its effects on the brain: neurotrophic signalling (such as BDNF), neurotransmitter modulation and the regulation of sleep and the stress response.

The compounds

This section spans ten compounds across three research themes. Each has its own page with a detailed mechanism, sourced study data, class, molecular weight and CAS.
