Question 1

Is Selank legal in Canada?

Accepted Answer

Selank is not an approved drug in Canada and is not authorized for human consumption. It may be legally supplied and purchased strictly as a research chemical for laboratory and educational use. Helixx sells Selank Canada-wide on that basis only. It must never be used for self-administration or in humans.

Question 2

How does Selank compare to benzodiazepines?

Accepted Answer

In a human trial, Selank produced anxiolytic effects comparable to the benzodiazepine medazepam but with additional antiasthenic effects and none of the dependence, tolerance, withdrawal or notable sedation associated with that drug class.1 Research also suggests it can potentiate the effect of the benzodiazepine diazepam.2

Question 3

How is Selank related to Semax?

Accepted Answer

Both are short synthetic Russian-developed peptides studied for nootropic and neuroprotective properties, and researchers often examine them side by side. Selank derives from tuftsin and is studied mainly for anxiolytic and GABAergic effects, whereas Semax derives from ACTH. They are frequently compared in the same research programs.

Question 4

What is the proposed mechanism of action?

Accepted Answer

The leading hypothesis is modulation of the GABAergic system: Selank alters the expression of genes controlling GABAergic neurotransmission in both brain tissue and human neuronal cells.34 It also upregulates BDNF and influences serotonin and dopamine signalling.5
