Selank: Reading a Research Base That Is Mostly Not in English

Provenance of the evidence

Selank is a synthetic analogue of the immunomodulatory peptide tuftsin, developed in Russia. Our index references around 41 studies, the majority published in Russian-language journals with limited independent replication elsewhere.

That is why the evidence grade is Limited: it reflects verifiability, not an assumption that the work is wrong.

Selank and Semax

The two are routinely mentioned together and share a development lineage, but they are different sequences studied for different endpoints. Vendor pages that treat them as variations of one product are not reliable sources.

Pricing

10mg vials typically run £16 to £24. Fewer vendors list Selank than the major categories, so price coverage in our index is thinner.

What to check

Confirm whether the listing is Selank or N-acetyl Selank amidate, a modified version with different stability characteristics that is frequently sold under the plain name.
