Selank: reading a small comparative anxiety study cautiously

Evidence discussed: Small comparative human study.

What the researchers studied

A Russian-language study with an English abstract compared Selank in 30 patients with medazepam in 32 patients with anxiety disorder or neurasthenia. Symptom scales and an enkephalin-related blood measure were evaluated; the authors reported similar anxiolytic effects. [1]

How to interpret the result

The small active-comparator report does not prove equivalence. Its abstract does not provide enough detail to independently assess all aspects of allocation, masking or longer-term safety. It also does not establish cognitive enhancement in healthy people.

What readers can take from it

This summary uses the indexed English abstract, not an independently reviewed translation of the complete Russian paper. Claims should remain proportional to the reporting available.

This original editorial summary provides no diagnosis, dosing or treatment advice. The study did not test or certify a PeptiKing product.
