Selank
Selank is a synthetic heptapeptide (a chain of seven amino acids) primarily recognized for its anxiolytic (anti-anxiety) and nootropic (cognitive-enhancing) properties.
Developed by the Institute of Molecular Genetics of the Russian Academy of Sciences, it was designed as a stable, synthetic analogue of tuftsin, a naturally occurring peptide in the human body involved in immune system regulation.
Key Characteristics & Benefits
Anxiety Reduction: It is often used to manage stress and generalized anxiety. Unlike traditional benzodiazepines, Selank is generally considered non-sedating and does not typically cause cognitive "fog," lethargy, or physical dependence.
Cognitive Support: It is categorized as a nootropic because it may improve focus, memory, and learning capacity, particularly during periods of high stress.
Neuroprotection: Research suggests it can increase the expression of Brain-Derived Neurotrophic Factor (BDNF), a protein essential for the survival and growth of neurons.
Immune Modulation: Because it is derived from tuftsin, it retains some ability to influence the immune system, potentially modulating inflammatory responses.
GABAergic System: It acts as a positive allosteric modulator of GABA receptors, which helps calm the central nervous system.
Monoamines: It influences the levels and metabolism of serotonin and dopamine, which are critical for mood regulation and motivation.
Enkephalins: It can inhibit the enzymes that break down enkephalins (natural pain-killing peptides), potentially prolonging their stress-reducing effects.
