The peptide Selank has been labeled as an “anti-anxiety” peptide and has also shown improvement in learning, memory, cognition, depression, weakness and overall energy. 


While most prescription drugs cause many unwanted side effects, studies have shown this peptide to have no negative side-effects or risk of addiction. Both Tuftsin and Selank have shown the ability to reduce anxiety and increase serotonin levels in animal models.

Additional benefits include:

  • Can improve anxiety 
  • Can improve learning
  • Can enhance memory 
  • Can strengthen immune function: Selank can increase IL-6 in blood cells. IL-6 is an inflammatory protein that is believed to help fight off infections. Selank can also stimulate the release of interferons, which are anti-viral molecules.
  • Can help with brain damage recovery: Increases BDNF (Brain-derived neurotrophic factor), an important brain-growth compound
  • Can help stabilize enkephalins in the blood -- these counteract the stress response
  • Can help with alcohol withdrawal
  • Can help prevent weight gain and reduce cholesterol

 Selank was originally developed as an anxiolytic (anti-anxiety) drug in Russia. It belongs to the class of synthetic peptide analogs of the naturally occurring peptide tuftsin. Tuftsin is known for its immunomodulatory and neuromodulatory effects. Selank has shown promise in various areas of research and clinical practice, including:

  1. Anxiety and Stress Reduction: Selank has demonstrated anxiolytic properties, helping to reduce anxiety and stress. It may be used as an alternative or adjunct to traditional anxiolytic medications.

  2. Mood Enhancement: Some individuals report improved mood and increased feelings of well-being with Selank usage. It may have a positive impact on overall mental state and emotional balance.

  3. Cognitive Enhancement: Selank has shown potential as a nootropic, enhancing cognitive functions such as memory, focus, and mental clarity. It may improve learning abilities and information retention.

  4. Neuroprotection: Studies suggest that Selank may exert neuroprotective effects by reducing oxidative stress and inflammation in the brain. It may have applications in neurodegenerative diseases and stroke recovery.

  5. Immune System Modulation: Selank has demonstrated immunomodulatory properties, potentially influencing immune system function. It may have applications in autoimmune disorders and chronic inflammation.

Functions: Selank exerts its effects through various mechanisms, although the exact mode of action is not yet fully understood. Some proposed mechanisms include:

  1. Regulation of Neurotransmitters: Selank may influence the levels and activity of neurotransmitters, including serotonin, dopamine, and norepinephrine. These neurotransmitters play crucial roles in mood regulation and stress response.

  2. BDNF Stimulation: Selank has been shown to increase brain-derived neurotrophic factor (BDNF) levels. BDNF is essential for the growth, survival, and maintenance of neurons, promoting neuroplasticity and cognitive function.

  3. Anti-inflammatory Effects: Selank exhibits anti-inflammatory properties by reducing the production of pro-inflammatory cytokines and inhibiting the activation of immune cells. This may contribute to its neuroprotective and immunomodulatory effects.

Benefits: The potential benefits of Selank include:

  1. Anxiolytic Effects: Selank may help alleviate symptoms of anxiety, promoting a calmer state of mind.

  2. Improved Mood: Users have reported an elevation in mood and a reduction in symptoms associated with depression.

  3. Enhanced Cognitive Function: Selank may improve memory, focus, and cognitive performance, potentially enhancing productivity and mental clarity.

  4. Neuroprotective Properties: The neuroprotective effects of Selank may have implications for neurodegenerative diseases, stroke recovery, and brain health in general.

SELANK & Brain🧠 Health

Brain Damage Recovery and BDNF Increase:

  • BDNF Enhancement: Brain-derived neurotrophic factor (BDNF) is a protein that plays a crucial role in promoting the growth, survival, and maintenance of neurons (nerve cells) in the brain. BDNF is often referred to as "brain fertilizer" due to its ability to support the growth and development of new neurons and synapses, which are vital for learning, memory, and overall brain function. Increased BDNF levels are associated with improved cognitive function and enhanced brain plasticity.

  • Neuroprotective Effects: Research suggests that Selank may have neuroprotective properties, which means it could help protect brain cells from damage caused by oxidative stress, inflammation, and other harmful factors. This neuroprotection could potentially contribute to the recovery of brain tissue following injury or damage.

  • Promoting Brain Healing: By increasing BDNF levels, Selank may support the brain's healing processes. BDNF promotes the growth and regeneration of neurons, aiding in the repair of damaged neural pathways. This could be particularly relevant for individuals recovering from brain injuries or conditions that affect brain function.

  • Enhanced Learning and Memory: The role of BDNF in synaptic plasticity—the ability of synapses to strengthen or weaken over time—is crucial for learning and memory. By promoting the growth of new synapses and supporting the existing ones, Selank's potential to increase BDNF could enhance cognitive abilities such as learning, memory consolidation, and information retention.

Dosages: The optimal dosage of Selank can vary depending on individual factors and the desired effects. It is usually administered via subcutaneous or intranasal routes. Common dosage ranges include:

  1. Subcutaneous Injection: Typical dosages range from 250 mcg to 1 mg per day. The injection is usually performed once or twice daily, with each dose divided equally.

  2. Intranasal Administration: Dosages for intranasal use range from 200 mcg to 400 mcg per day. This is usually divided into several smaller doses throughout the day.
