In the beginning of 80-s Russian Academy of Science became interested in testing various peptides. A breakthrough came in 1995, when one of them - Tafcin - appeared to have anxiolytic effects in animals. Over the next decade researchers managed to develop Selank (Thr-Lys-Pro-Arg-Pro-Gly-Pro) a synthetic analogue of the peptide that was able to have the most pronounced anxiolitic properties. The clinical trials lasted up to 2009, when Selank was finally brought to the market under the brand name SELANK® 0,15%.

Primary indications:

- Anxiety-asthenic disorders

- Stress and pressure at school or at work
