Pure Peptides

Cognitive & Neuropeptide Research

Nootropic and neuropeptide compounds for cognitive and neurological pathway research, including Semax, Selank, and Dihexa.

Cognitive and neuropeptide compounds are studied for their influence on BDNF signalling, neurotransmitter regulation, and neuroplasticity. Semax is an ACTH(4–10) analogue developed at the Institute of Molecular Genetics in Moscow, investigated as a BDNF and VEGF modulator. Selank is a tuftsin analogue studied for anxiolytic and GABAergic effects. Dihexa is among the most active pro-cognitive compounds in pre-clinical models. Orexin A and B regulate hypothalamic arousal and appetite circuits.
