Selank
Selank – 11mg (Lyophilized Peptide) – For Research Use Only
Selank is a synthetic peptide analog of the naturally occurring tetrapeptide Tuftsin, extensively studied for its potential nootropic, anxiolytic, and immunomodulatory properties. Research suggests that Selank may support cognitive function, anxiety reduction, and immune system regulation through its interaction with neurotransmitter systems, particularly GABA and serotonin pathways.

Selank peptide Details
Selank is a synthetic analog of the endogenous immunomodulatory peptide tuftsin, developed by the same Russian research group responsible for Semax. Structurally extended for metabolic stability, Selank has been studied primarily for its anxiolytic (anti-anxiety) and nootropic properties without the sedation or dependency profile associated with benzodiazepine-class compounds. Research has examined its effect on GABAergic tone, monoamine (serotonin/dopamine) balance, and expression of BDNF, positioning it as a peptide of interest for stress modulation, emotional regulation, and cognitive resilience under pressure. As with Semax, Selank carries an existing regulatory registration in Russia as a prescription nasal-spray anxiolytic, and much of the peer-reviewed literature originates from that clinical context, with an expanding body of international preclinical research into its neuroimmune signaling properties.
Selank peptide Scientific Research
- GABAergic System Modulation
Selank is widely used in studies investigating central GABA-A receptor signaling. It is evaluated for its ability to influence inhibitory synaptic tone and neuroplasticity-related mechanisms in rodent brain tissue models. - Neuroimmune Regulation and Cytokine Activity
In controlled in-vitro systems and in-vivo experiments, Selank has been shown to alter the expression of interleukins such as IL-6 and modulate pathways associated with immune–neural crosstalk, particularly in inflammation and stress-related studies. - Neurotransmitter-Linked Gene Expression
Selank is investigated for its transcriptional influence on BDNF and other genes associated with dopaminergic and serotonergic systems. Researchers often measure its effects on enkephalin-degrading enzymes and monoamine metabolism. - Stress Response and Behavioral Studies
Rodent behavioral paradigms using Selank include elevated plus maze, open field, and restraint stress tests, aimed at exploring peptide-based regulation of anxiety and emotional behavior under CNS-relevant conditions.
5. Peptide Stability and Pharmacodynamics
Due to its synthetic structure and neurobiological relevance, Selank is utilized in pharmacokinetic and receptor engagement studies, especially those analyzing long-acting peptide stability in biological systems.
