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
~20-60 minutes (extended over parent Selank)
100–400 mcg
1-2 times daily
14-30 days
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
Mechanism of Action
Same GABAergic and serotonergic modulation as Selank with improved pharmacokinetic profile
N-acetyl group confers resistance to aminopeptidase degradation
Enhanced blood-brain barrier penetration increases central anxiolytic and nootropic activity
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
Storage & Reconstitution
Unreconstituted (Powder)
Reconstituted (Mixed)
Note: Protect from light. Do not freeze reconstituted solution.
Research Summary
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.
