Buy Selank Peptide (Nootropic and Anxiolytic Peptide).

Selank is a synthetic analogue of the immunomodulatory peptide Tuftsin, and a heptapeptide with the sequence Thr-Lys-Pro-Arg-Pro-Gly-Pro, chemical formula C33H57N11Oand molar mass 751.887 g·mol−1. Tuftsin is a tetrapeptide (Thr-Lys-Pro-Arg) located in the Fc-domain of the heavy chain of immunoglobulin G (residues 289-292). Tuftsin has an immunostimulatory effect. Both, Tuftsin and Selank have the ability to reduce anxiety and increase serotonin levels.

Selank was developed at the Institute of Molecular Genetics (Russian Academy of Sciences) in cooperation with the V.V. Zakusov Research Institute of Pharmacology (Russian Academy of Medical Sciences), along with another nootropic drug Semax.

Selank chemical structure


Nootropics are smart drugs and cognitive enhancers, supplements, that may improve cognitive function, particularly executive functions, memory, creativity, or motivation, in healthy individuals. An anxiolytic is a medication, that inhibits anxiety. This effect is in contrast to anxiogenic agents, which increase anxiety. Some recreational drugs such as alcohol induce anxiolysis initially; however, studies show that then many of these drugs are anxiogenic. Anxiolytic medications have been used for the treatment of anxiety disorder and its related psychological and physical symptoms. Light therapy and other interventions have also been found to have an anxiolytic effect.


Interleukin 6 (IL-6) is an interleukin that acts as both a pro-inflammatory cytokine and an anti-inflammatory myokine. IL-6’s role as an anti-inflammatory myokine is mediated through its inhibitory effects on TNF-alpha and IL-1, and activation of IL-1ra and IL-10. There is some early evidence that IL-6 can be used as an inflammatory marker for severe COVID-19 infection with poor prognosis, in the context of the wider coronavirus pandemic.


Selank, as well as a related peptide drug, Semax, have been found to inhibit enzymes involved in the degradation of Enkephalins (it inhibits Enkephalin hydrolysis) and other endogenous regulatory peptides, and this action may be involved in their effects

Peptides Prefer the Cold

Keep peptide vials refrigerated at all times to reduce peptide bond breakdown. DO NOT FREEZE. Most peptides, especially shorter ones, can be preserved for weeks if careful.

Always swab the top of the vial with an alcohol wipe, rubbing alcohol or 95% ethanol before use.

Before drawing solution from any dissolved peptide vial, fill the pin with air to the same measurement you will be filling with solution, ie. if you plan to take 0.1 ml, first fill the pin with 0.1ml of air, push the air into the vial, and then draw the peptide back up to the 0.1 ml marker. Doing so will maintain even pressure in the vial. Always remember to remove air bubbles from the pin by flicking it gently, needle side up, and pushing bubbles out. In addition, push out a tiny amount of solution to ensure there is no air left in the metal tip.


Only Mix With Sterile Bacteriostatic Water

The purity and sterility of bacteriostatic water are essential to prevent contamination and to preserve the shelf-life of dissolved peptides.

Push the pin through the rubber stopper at a slight angle, so that you inject the bacteriostatic water toward the inside wall of the vial, not directly onto the powder.

Lyophilized peptide should be stored at -20°C (freezer), and the reconstituted peptide solution at 4°C (refrigerated). Do not freeze once reconstituted.


Do Not Shake Vial To Mix

Air bubbles are unfavorable to the stability of proteins.
