This research blend combines two well-studied synthetic neuropeptides — Selank and Semax — in equal 10mg quantities per vial (20mg total). Both peptides were originally developed at the Institute of Molecular Genetics of the Russian Academy of Sciences and have been investigated extensively for their effects on the central nervous system, neurotransmitter systems, and neurotrophic signaling.

Selank is a synthetic heptapeptide analog of tuftsin, an endogenous immunomodulatory peptide. Research studies have examined its role in modulating GABAergic and serotonergic neurotransmission, influencing anxiolytic pathways without the sedative profile typical of benzodiazepines. Additional investigations have explored its effects on BDNF (brain-derived neurotrophic factor) expression, immune regulation, and enkephalin metabolism.

Semax is a synthetic heptapeptide derived from a fragment of adrenocorticotropic hormone (ACTH 4-10), modified to remove hormonal activity while retaining neurotropic effects. Research has focused on its influence on BDNF and NGF (nerve growth factor) expression, dopaminergic and serotonergic systems, neuroprotection in ischemic models, and cognitive and attentional pathways.

Research areas exploring this combination include:

  • Neurotrophic factor expression (BDNF, NGF)
  • Anxiolytic and stress-response pathways
  • Cognitive performance and memory consolidation
  • Neuroprotection and neuroregeneration models
  • Neurotransmitter system modulation (GABA, serotonin, dopamine)
  • Immune-nervous system crosstalk
