Selank

Well Studied

Anxiolytic & Nootropic Peptide | Tuftsin Analog

Dose 250-500mcg per dose
Frequency 1-2x daily (morning and/or evening)
Cycle 2-8 weeks on
Storage Reconstituted: 2-8°C, use within 30 days

Selank is a synthetic heptapeptide analog of the naturally occurring immune peptide tuftsin, developed by the Russian Academy of Sciences. It provides anxiolytic effects comparable to benzodiazepines but without sedation, amnesia, tolerance, or withdrawal.

Mechanism of Action

Works through allosteric modulation of GABA-A receptors, serotonin and dopamine system optimization, enkephalin degradation inhibition, IL-6 and cytokine balance regulation, and BDNF upregulation in the hippocampus.

Key Benefits

  • Rapid onset anxiolytic effects
  • Enhanced BDNF expression (30% increase)
  • Improved stress resilience
  • Cognitive enhancement
  • Immune modulation
  • No tolerance or withdrawal
  • Neuroprotective effects

Anxiety

  • Generalized Anxiety Disorder

    Clinical trials show significant reduction in anxiety symptoms comparable to benzodiazepines but without sedation or amnesia.

  • Post-Traumatic Stress Disorder

    Research indicates effectiveness in PTSD treatment.

  • Social Anxiety

    Reduces anticipatory anxiety and performance stress.

Cognitive

  • Memory Enhancement

    Improves memory consolidation and learning capacity.

  • Attention and Focus

    Enhanced sustained attention during demanding cognitive tasks.

  • Neuroprotection

    BDNF upregulation supports long-term brain health.

Immune

  • Immune Modulation

    Balances immune system function through cytokine regulation.

  • Antiviral Activity

    Shows activity against influenza, HSV, and cytomegalovirus.

  • Inflammation Regulation

    Modulates inflammatory gene expression.

Subcutaneous injection is the primary method with well-documented protocols. Provides reliable absorption and dosing.

Reconstitution Instructions

Materials Needed:
  • Selank lyophilized powder vial
  • Bacteriostatic water
  • Insulin syringes (29-31 gauge)
  • Alcohol wipes
  • Sterile work surface
  1. 1 Remove vial from refrigeration; allow 10-15 minutes to reach room temperature
  2. 2 Clean vial tops with alcohol wipes using circular motion; air dry
  3. 3 Calculate reconstitution volume for desired concentration
  4. 4 Draw bacteriostatic water into insulin syringe; remove air bubbles
  5. 5 Insert needle at 45-degree angle against glass wall
  6. 6 Slowly inject BAC water down vial side to minimize foaming
  7. 7 Remove needle and gently swirl vial (never shake vigorously)
  8. 8 Allow 1-2 minutes if cloudiness remains; swirl until clear
  9. 9 Verify final solution is clear and colorless
  10. 10 Label with reconstitution date and concentration
  11. 11 Refrigerate immediately; use within 30 days
