WHAT IS SELANK PEPTIDE?

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. 

Benefits of Selank

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.

Additionally, selank may:

• Improve anxiety 
• Improve learning
• Enhance memory 
• Help with brain damage recovery: Increases BDNF (Brain-derived neurotrophic factor), an important brain-growth compound
• Help stabilize enkephalins in the blood: These counteract the stress response
• Help with alcohol withdrawal
• Help prevent weight gain and reduce cholesterol

Selank can strengthen immune function by increasing 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.

What is Selank?

Selank belongs to a class of molecules called synthetic peptides. Selank was made by combining the sequence of a peptide called tuftsin with another sequence that improves its molecular stability. Tuftsin is a peptide closely related to immune function. It occurs naturally and makes up one part of the natural antibody IgG.

It is a small peptide compared to most naturally occurring proteins. Selank was developed at the Institute of Molecular Genetics in cooperation with the V.V. Zakusov Research Institute of Pharmacology (Russian Academy of Medical Sciences), along with the nootropic drug Semax, sometimes called its cousin peptide. 

How do you use Selank?

Selank is a peptide used as a nasal spray. This is because it will be digested by the stomach if taken orally. Inhaling is more effective for delivery to the bloodstream and into the brain.

The typical dosage is one spray in each nostril daily.

Research

In clinical trials, the drug has been shown to provide a sustained nootropic and anxiolytic effect, which is useful for the treatment of generalized anxiety disorder (GAD).  Selank has an advantage over traditional anxiety treatments, such as benzodiazepines, as it has no sedating or negative cognitive side effects and no associated addiction or withdrawal problems. Selank has been approved in Russia for treating generalized anxiety disorder (GAD) and its use as a nootropic.

Although limited, some evidence suggests that Selank may help curb anxiety and offer many other benefits. More research is always needed to monitor its effectiveness and safety.
