N-Acetyl Selank at a glance

NameN-Acetyl Selank
Also known asN-Acetyl Selank Amidate, NA-Selank
CategoryCognitive & neuroprotective
TypePeptide
SequenceN-acetylated analog of Selank, a synthetic heptapeptide based on the immunomodulator tuftsin
Typical dose~250-900 mcg per day (commonly cited)
FrequencyOnce daily or divided into two or three applications
RouteIntranasal (research)
Half-lifeReported longer than unmodified Selank, still relatively short (hours).

Overview

N-Acetyl Selank is a modified form of Selank, a synthetic peptide derived from the endogenous tetrapeptide tuftsin. The acetylation is described as intended to increase stability. As with Semax, most data originate from Russian research settings, and large-scale international clinical trials are absent. Included for educational context only.

How it’s thought to work

  • Reported to modulate GABAergic and serotonergic signaling.
  • Appears to influence expression of brain-derived neurotrophic factor (BDNF).
  • Studied for effects on the balance of pro- and anti-inflammatory cytokines.

Researched uses

  • Anxiety-like behavior in animal and early human studies
  • Cognitive and memory support in exploratory research
  • Stress resilience and mood regulation

Commonly cited protocol

Typical dose~250-900 mcg per day (commonly cited)
FrequencyOnce daily or divided into two or three applications
RouteIntranasal (research)
NotesApplied as nasal drops or spray; the acetyl form is cited as more stable than plain Selank.

Reconstitution

Typically sold as a ready-to-use intranasal solution, so injection unit math does not apply.

Cautions

  • Not FDA-approved; classified as a research chemical in most markets.
  • Evidence base is largely limited to Russian studies.
  • Concentration and purity differ between suppliers.
  • Long-term safety is not established.
