// Overview

What is Selank?

Selank (Thr-Lys-Pro-Arg-Pro-Gly-Pro) is a synthetic heptapeptide derived from the naturally occurring immunomodulatory peptide tuftsin (Thr-Lys-Pro-Arg), with an added Pro-Gly-Pro tail for enzymatic stability. Developed at the same Russian institute as Semax, Selank was approved in Russia in 2009 for treatment of generalized anxiety disorder and neurasthenic conditions.

Selank provides anxiolytic (anti-anxiety) effects comparable to benzodiazepines but without sedation, cognitive impairment, addiction potential, or withdrawal symptoms. It achieves this through modulation of GABA, serotonin, and enkephalin systems, as well as immunomodulatory effects through its tuftsin heritage.

The combination of anxiolytic and nootropic effects makes Selank unique among anti-anxiety compounds. Users typically report calm focus rather than sedated relaxation — an ideal state for productivity and social situations where anxiety would otherwise impair function.

// How It Works

How Selank Works

Selank modulates anxiety through multiple neurotransmitter systems:

  1. GABAergic enhancement — Allosterically modulates GABA-A receptor function, enhancing inhibitory neurotransmission without directly binding the benzodiazepine site. This avoids sedation and dependence.
  2. Serotonin modulation — Affects serotonin metabolism and 5-HT receptor expression in the brain, contributing to mood stabilization and anxiolysis.
  3. Enkephalin stability — Inhibits enkephalinase, increasing endogenous enkephalin (endorphin) levels. This provides natural analgesic and mood-elevating effects.
  4. BDNF expression — Like Semax, Selank increases BDNF levels, providing nootropic effects alongside anxiolysis.
  5. Immune modulation — The tuftsin backbone activates natural killer cells and phagocytes, providing subtle immune support alongside neurological effects.

Dosage Information (User-Reported)

Disclaimer: Dosage information is compiled from user reports and published research. This is not medical advice. Consult a healthcare professional before use.
Level Dose Frequency Duration
Anxiolytic 250-500 mcg 2-3x daily (intranasal) 14-21 day cycles
Stress Management 300 mcg 2-3x daily (intranasal) As needed
Immune Support 500 mcg 2-3x daily (intranasal) 14 days

What to Expect

First Dose

Calming effect within 15-30 minutes. Reduced mental chatter and anxiety. No sedation — clarity maintained. Social anxiety diminishes.

Day 1-3

Consistent anxiolysis with each dose. Improved ability to handle stressful situations. Sleep may improve from reduced evening anxiety.

Day 7-14

Cumulative mood stabilization. Anxiety episodes less frequent and less intense. Cognitive function enhanced rather than impaired.

Post-Cycle

Anxiolytic effects may persist for days after discontinuation. No withdrawal symptoms or rebound anxiety (unlike benzodiazepines).
