NA-Selank

NA-Selank

Also known as: N-Acetyl Selank, Acetylated Selank, NA-Selank Amidate

Overview

Key Facts

Primary Goal: Research and therapeutic applications of NA-Selank

Same GABAergic and serotonergic modulation as Selank with improved pharmacokinetic profile. N-acetyl group confers resistance to aminopeptidase degradation.

Dosing Information

Half-Life

~20-60 minutes (extended over parent Selank)

Typical Dose

100–400 mcg

Frequency

1-2 times daily

Cycle Length

14-30 days

Administration Routes:
subcutaneous

Benefits

  • Stronger and longer-lasting anxiolytic effects compared to standard Selank
  • Improved metabolic stability over parent peptide
  • Enhanced cognitive focus and mental clarity
  • Preserved immunomodulatory activity
  • Greater CNS bioavailability due to acetylation

Side Effects

Mild nasal irritationmild
Occasional headachemild
Less clinical data available compared to standard Selankmild
Rare reports of transient brain fog at initiationmild

Mechanism of Action

1

Same GABAergic and serotonergic modulation as Selank with improved pharmacokinetic profile

2

N-acetyl group confers resistance to aminopeptidase degradation

3

Enhanced blood-brain barrier penetration increases central anxiolytic and nootropic activity

4

Retains tuftsin-derived immunomodulatory properties

Contraindications

Do not use this peptide if any of the following apply:

  • Pregnancy or breastfeeding
  • Active autoimmune conditions
  • Known hypersensitivity to Selank or tuftsin-derived peptides

Research Summary

Preclinical

NA-Selank is a pharmacokinetically optimised derivative of Selank designed to overcome the rapid enzymatic degradation that limits the parent peptide's duration of action. While standard Selank has extensive Russian clinical data, the acetylated form has been studied primarily in in vitro and preclinical settings. Research confirms the N-acetyl modification significantly extends the peptide's plasma half-life while preserving its anxiolytic and immunomodulatory pharmacology. It is widely used in research communities as an enhanced-stability alternative to Selank.
