N-Acetyl Selank Amidate

NA-Selank · N-Acetyl-Selank · Selank Amidate

N-Acetyl Selank Amidate is a modified, more stable version of Selank, a synthetic peptide analogue of the naturally occurring immunomodulatory peptide tuftsin. Selank was developed at the Institute of Molecular Genetics of the Russian Academy of Sciences and has been approved in Russia as an anxiolytic since 2009. The N-acetyl amidate modification protects the peptide from rapid enzymatic degradation, resulting in improved bioavailability and a longer duration of action compared to native Selank.,Selank acts primarily through modulation of the GABAergic and serotonergic systems, and it influences the expression of brain-derived neurotrophic factor (BDNF) and several interleukins. Unlike benzodiazepines, it does not produce sedation, cognitive impairment, or dependence at standard doses. Research has focused on its anxiolytic, nootropic, and immunomodulatory properties.,While Selank is an approved pharmaceutical in Russia, N-Acetyl Selank Amidate specifically remains a research compound outside of Russia. Clinical trials of the parent compound Selank have been conducted in Russian institutions, but Western regulatory agencies have not evaluated or approved either form.

How it works

Modulates GABAergic neurotransmission and enhances the inhibitory effect of GABA, producing anxiolytic effects without sedation or dependence.,Increases expression of brain-derived neurotrophic factor (BDNF) and influences serotonin metabolism, supporting neuroplasticity and mood regulation.,Modulates cytokine expression (IL-6, IL-10) and influences T-helper cell balance, contributing to immunomodulatory effects.

Interactions & stacking

What's safe to combine, and what belongs in a separate pin.

Safe & synergistic

BPC-157Tissue repair peptide and anxiolytic peptide act through independent mechanisms
EpithalonTelomerase activation and anxiolytic effects are independent pathways
Thymosin Alpha-1Immune modulation and anxiolytic effects do not conflict
KPVAnti-inflammatory peptide and anxiolytic peptide have non-overlapping mechanisms

Keep separate

GHK-CuCopper-peptide complex may degrade Selank via metal-catalyzed oxidation - do not mix in same syringe
