Availability in Thailand

Selank is available from Thai peptide vendors as a nasal spray. It is not typically offered at Thai clinics, as it is primarily a self-administered nootropic peptide used for anxiety reduction and stress relief.

Prescription: Not required from peptide vendors in Thailand.

Legal status: Approved as a prescription anti-anxiety medication in Russia. Available as a research peptide in Thailand.

Overview

Selank is a synthetic heptapeptide based on the immune-regulating peptide tuftsin, with added anxiolytic (anti-anxiety) properties. Developed in Russia and approved there as a prescription anti-anxiety medication, it modulates GABA activity and serotonin metabolism in the brain to reduce anxiety and improve emotional stability — without the sedation, dependence, or cognitive impairment associated with benzodiazepines.

How It Works

GABA modulation

Selank enhances GABAergic neurotransmission, increasing the activity of the brain's primary inhibitory neurotransmitter. This produces anxiolytic effects similar to benzodiazepines but without sedation, tolerance development, or withdrawal symptoms.

Serotonin metabolism

Modulates serotonin and its metabolites in the brain, stabilising mood and reducing the excessive neural activation associated with anxiety and stress responses.

Immune modulation

Based on tuftsin — a naturally occurring immune peptide — selank also has immunomodulatory properties. It can help regulate immune function, which research increasingly links to brain health and mental well-being through the gut-brain-immune axis.

BDNF influence

Like semax, selank also increases BDNF, supporting neuroplasticity and cognitive resilience. However, its primary effect is anxiolytic rather than cognitively stimulating.

Protocol Quick Reference

starting Dose
250-300 mcg (2-3 drops per nostril) 1-2 times daily
maintenance Dose
300-600 mcg per day, divided into 2-3 doses
escalation
Start with lower doses for the first 3-5 days to assess response
injection Sites
Not applicable — nasal spray
full Titration
3-5 days at starting dose
cycle Length
14-21 days is the standard Russian protocol. Rest 14 days between cycles
storage
Refrigerated
reconstitution
Usually supplied as pre-mixed nasal spray
timing
Afternoon and evening preferred. Can be used any time anxiety symptoms are present
special Notes
Selank can be used situationally (before stressful events) or as a daily cycle. It pairs well with semax — semax in the morning for cognitive performance and selank in the afternoon/evening for anxiety management and calm.

Benefits & Uses

  • Anxiety reduction: Reduces anxiety through GABAergic modulation without the sedation or dependence of benzodiazepines
  • Stress resilience: Improves the ability to handle stressful situations with greater emotional stability
  • No sedation or dependence: Unlike traditional anti-anxiety medications, selank does not cause drowsiness, cognitive impairment, or physical dependence
  • Mood stabilisation: Balances serotonin metabolism for more consistent emotional states
  • Pairs with semax: Selank (calm) + semax (focus) creates a balanced cognitive enhancement stack
  • No injection needed: Nasal spray administration — convenient and non-invasive

Side Effects

Common

  • Mild nasal irritation
  • Mild fatigue — not sedation, but a calming effect that some interpret as tiredness

Less Common

  • Headache
  • Mild dizziness

Serious

  • Generally well-tolerated with clinical use in Russia
  • No physical dependence or withdrawal reported
  • No cognitive impairment — can be used while working or driving
  • May potentiate the effects of other anxiolytics or sedatives — use caution with combinations

FAQ

Is selank addictive like benzodiazepines?

No. Selank does not produce physical dependence, tolerance, or withdrawal symptoms. While it modulates GABA similarly to benzodiazepines, it does so through a different mechanism that avoids the dependency pathway. It can be stopped without tapering.

Can I use selank with semax?

Yes — this is one of the most popular nootropic peptide stacks. Semax provides cognitive stimulation and focus, while selank provides calm and anxiety reduction. Together they create a balanced state of focused calm. Typically semax is used in the morning and selank in the afternoon or evening.

Will selank make me drowsy?

No. Unlike benzodiazepines, selank reduces anxiety without causing sedation or cognitive impairment. You can use it while working, driving, or performing tasks that require focus.

How quickly does selank work?

Effects are typically noticeable within 15-30 minutes of nasal administration. For ongoing anxiety, consistent daily use over a 14-21 day cycle produces more sustained benefits.
