The verdict

Depends — Selank has a coherent Russian trial base for generalized anxiety disorder, but the entire evidence record is single-source (Institute of Molecular Genetics RAS), there is no Western replication, and the serotonergic interaction profile is real for the population most likely to be tempted by it.
