In the world of mental health, antidepressants play a powerful role by influencing key messengers in the brain—dopamine and serotonin. These messengers control our emotions, motivation, and pleasure. Antidepressants, especially selective serotonin reuptake inhibitors (SSRIs), shine a spotlight on serotonin, the calm conductor linked to mood stability, by increasing its presence. At the same time, dopamine, the energetic performer associated with reward and motivation, adds to the overall harmony. This article explores a supplement called Selank Peptide, known to adjust the levels of these messengers, offering support to those facing depression and generalized anxiety disorders.

Selank is a synthetic version of Tuftsin, a peptide produced by the spleen. Peptides are like tiny chains made up of building blocks called amino acids, and they serve various important functions in the body, such as signaling and regulating biological processes. Both Selank and Tuftsin are known to have immunomodulatory properties, which means they can enhance and regulate the immune system.

Selank can influence the release of naturally occurring proteins and powerful neurotransmitters such as Dopamine and Serotonin. These chemicals in the brain play a crucial role in regulating our mood, appetite, and sleep-wake cycles. When these chemicals are deficient, it can lead to depression, loss of appetite, and difficulty sleeping.

Selank Peptide – Product Information

Selank is a synthetic peptide that has been studied for its potential anxiolytic (anti-anxiety) and nootropic (cognitive-enhancing) effects. This synthetic analog has a chemical structure based on a naturally occurring peptide called tuftsin. Its full chemical name is N-acetyl-L-seryl-L-tyrosyl-L-valyl-L-valyl-L-seryl-L-prolyl-L-seryl-L-threonine. {R}

With its modulation of neurotransmitter activity, including serotonin and BDNF, the product offers potential benefits of cognitive enhancement and potential neuroprotective properties.

Selank is typically administered via subcutaneous injection and nasal sprays, but the specific dosage and administration protocol can vary. It’s important to follow recommended guidelines or consult with a healthcare professional if considering its use.

Selank may be available from various sources, including online suppliers and research chemical vendors such as Purerawz, Behemoth Labz, and RCD.Bio.

Selank Peptide – Mechanism of Action

Selank appears to interact with various neurochemical pathways, influencing neurotransmitter levels and receptor activity. Below are some aspects of its molecular genetics and proposed mechanism of action:

Image source:

Modulation of Neurotransmitters: Selank is believed to modulate the activity of neurotransmitters, particularly serotonin. Serotonin is a neurotransmitter involved in mood regulation, and alterations in its levels are associated with anxiety and depressive disorders. Selank may enhance the activity of serotoninergic pathways, contributing to its anxiolytic effects. {R}

BDNF Modulation: Brain-derived neurotrophic Factor (BDNF) is a protein that plays a crucial role in neuronal survival, growth, and differentiation. Selank has been suggested to influence the expression of BDNF, potentially contributing to its cognitive-enhancing effects. BDNF is associated with synaptic plasticity and learning and thus makes selank an important brain growth compound. {R}

GABAergic System: Selank may interact with the gamma-aminobutyric acid (GABA) system, which is the major inhibitory neurotransmitter in the central nervous system. Modulation of GABAergic activity is linked to anxiolytic effects, and Selank’s influence on this system could contribute to its anti-anxiety properties. {R}

Opioid System: Some studies suggest that Selank may interact with the opioid system. Opioid receptors are involved in pain modulation and mood regulation. The interaction with this system could contribute to Selank’s overall effects on emotional well-being. {R}

Anti-Inflammatory and Antioxidant Effects: Selank has demonstrated anti-inflammatory and antioxidant properties in preclinical studies. These effects may contribute to its neuroprotective potential and could be relevant in conditions involving oxidative stress and inflammation. {R}

It’s important to note that the understanding of Selank’s mechanism of action is still evolving, and additional research is going to fully elucidate its effects at the molecular and cellular levels.

Selank Peptide Benefits:

Selank is a synthetic peptide that has been studied for its potential therapeutic effects, particularly in the fields of anxiety and cognitive enhancement. Some of it numerous potential benefits are discussed below:

1. Anxiolytic Effects:

Selank has shown potential anxiolytic (anti-anxiety) effects in preclinical and clinical studies and is best known to reduce anxiety. It is believed to modulate the expression of certain neurotransmitters, including serotonin, which plays a role in mood regulation and for treatment of any generalized anxiety disorder. {R}

2. Cognitive Enhancement:

Some studies suggest that Selank has cognitive-enhancing effects. It is thought to influence the levels of brain-derived neurotrophic factor (BDNF), a protein associated with cognitive function, learning, and memory.

3. Antioxidant/ Ant-Aging Properties:

Selank has demonstrated antioxidant properties in animal studies. Antioxidants help protect cells from oxidative stress, which is implicated in various health conditions and most importantly, aging. {R}

4. Immunomodulatory Effects:

Selank has immunomodulatory effects, potentially affecting the activity of immune cells. This could have positive implications on the overall immune function and for conditions related to immune system dysregulation. {R}

5. Potential for PTSD Treatment:

Research has explored the potential use of Selank in post-traumatic stress disorder (PTSD) treatment. Preliminary studies suggest that it may have a beneficial impact on symptoms associated with PTSD. {R}

6. No Withdrawal problems:

Selank has an advantage over traditional anxiety treatments such as benzodiazepines. It has no sedating or negative cognitive side effects, and there are no associated addiction or withdrawal problems with the use of this amazing anti-depressant. {R}

Side Effects:

Selank has been reported to have a favorable safety profile, with limited side effects reported in clinical trials. However, some individuals may experience mild and transient side effects which include:

Mild Sedation:

Some users have reported feeling mildly sedated, which could be related to its anxiolytic effects.

Drowsiness or Fatigue:

In some cases, individuals may experience drowsiness or fatigue, especially when using higher doses.

Allergic Reactions:

Although rare, some individuals may be allergic to specific components of the peptide. If someone experiences symptoms of an allergic reaction, such as rash, itching, or swelling, they should seek medical attention.

Is it Legal?

According to clinical studies, peptide selank has been found to have similar effects to tranquilizers at low doses, but without the undesirable side effects associated with tranquilizers. It is important to note that selank is only legally available for purchase as a research chemical and is intended for research purposes only. It is not approved for human consumption or medical use in most countries.


According to anecdotal evidence, the recommended dosage of Selank is 2-3 drops in each nostril, up to three times a day. The treatment should last for a maximum of two weeks. In the case of injectables, the dosage should range between 150-300mcg per injection.
