Description
N-Acetyl Selank is an acetylated version of Selank, a synthetic peptide derived from the immune peptide tuftsin. Limitless Life Nootropics supplies it in 20mg and 30mg vials, made in the USA and independently tested.
What Is N-Acetyl Selank?
Selank was developed at the same Russian institute that created Semax. It is based on tuftsin (Thr-Lys-Pro-Arg), a natural tetrapeptide fragment of immunoglobulin G, extended with a Pro-Gly-Pro tail for stability. The result is the heptapeptide Thr-Lys-Pro-Arg-Pro-Gly-Pro.
Preclinical research has explored the peptide’s effects on GABAergic signaling, enkephalin metabolism, serotonin and immune markers such as interleukin-6. It is frequently studied in models of anxiety and stress, where investigators look for anxiolytic-like effects without the sedation associated with benzodiazepines.
The N-acetyl modification is designed to slow N-terminal enzymatic breakdown. Both Premium lyophilized and Non-Lyophilized grades are available in 20mg and 30mg sizes.
Areas of Scientific Investigation
Laboratory studies have explored this peptide across several areas of investigation:
- GABA-A receptor modulation studies
- Anxiety and stress paradigms in rodents
- Enkephalin-degrading enzyme activity
- Immune cytokine expression (IL-6, interferon)
- Comparisons with non-acetylated tuftsin analogs
Researchers can review peer-reviewed studies on this compound through the National Library of Medicine (PubMed) database.
