Selank 5mg Vial

The neuropeptide is the synthetic variant of the self-made peptide Tuftsin. Selank belongs to the hexapeptides and has a wide spectrum of modes of action and applications. Selank is used in American medicine, inter alia, to combat anxiety and phobias. The effect of Selank is very similar to the effect of the sedative benzodiazepines, but without the numbing, so sedative side effects. As a substitute for extreme medications such as anxiolytics and nootropics, Selank can be used to fight depression, anxiety and anxiety in general. In addition, Selank reduces mental stress, which in turn has a positive effect on various areas.

Selank is closely related to the peptide Semax, also a recently developed peptide. However Selank should be the much more efficient variant of these two peptides. In Germany, these peptides are still very unknown due to the lack of marketing and ignorance in this field.


Selank acts as a better nootropic agent because of its above mentioned close resemblance to the body’s own peptide Tuftsin. It therefore increases the user’s focus and general concentration ability, reduces mental fatigue, sharpens mental acuity and increases the memory capacity for learning processes. The first vocal effect is usually the stabilization of mood, as well as a greatly improved general well-being.

In addition to the effects mentioned Selank also helps to a much more powerful immune system. This is noticeable, for example, in the fact that users become much less likely to become ill, even if they are exposed to extremely contagious influenza infections in their environment.

One of the mechanisms by which Selank gains its benefits is by increasing serotonin, a neurotransmitter most commonly known to regulate mood, but also has an effect on appetite and sleep. A lack of serotonin can lead to depression, loss of appetite and insomnia. Selank also has significant modulatory effects on the body’s natural opioid system, leading to an increase in endorphin levels and subsequent improvement in well-being and overall mood. In addition, Selank is working to increase dopamine levels, another neurotransmitter that is directly involved in many important functions such as cognition, motivation, mood, memory, sleep, and learning.

The application period is between 10 days and the open end, depending on what the user uses it for.

The subcutaneously injected dose varies between 250mcg and 3mg depending on the area of ​​application. For example, if you use Selank for exam preparation or a glasswork appointment, you should drive well with a dosage of 250-500mcg. Dosages beyond this limit are used to combat depression, severe anxiety, etc.

Low doses, at 250-500mcg, is enough to inject once a day in the morning. Higher doses should be divided into two injections, morning and evening.

Side effects:

At doses between 250-500mcg no side effects are known. Due to the very mild toxicity of Selank, a higher dosage can lead to Fatigue.
