Selank

Limited human dataBrain, mood & sleep

A nasal peptide based on tuftsin, used as a non-sedating anti-anxiety agent.

Approved in Russia (nasal drops) for anxiety; not approved elsewhere.

Used for

  • Anxiety and stress
  • Calm focus

How it works

Seems to modulate GABA signaling and slow the breakdown of enkephalins (the body’s own opioid peptides).

What the research shows

  • Lab and rat studies show enkephalin-enzyme inhibition and effects on GABA genes.
  • Russian clinical studies in anxiety disorders report benefits similar to a benzodiazepine; few are available in English.

Side effects

  • Nasal irritation
  • Mild tiredness

Cautions

  • Research-chemical vials have no quality control: purity, dose and sterility vary. Third-party testing helps but is no guarantee.

Storage

Unmixed powder: freezer or fridge, away from light.

Once mixed with bacteriostatic water: fridge; the common rule is to use it within 28 days.

There is no label or published stability data for this one, so treat these as habits, not limits.
