§ Clinical Evidence
Selank anxiolytic effects in humans
Clinical trial demonstrates Selank's anxiolytic efficacy in patients with generalized anxiety disorder, comparable to benzodiazepines but without sedation or dependence.
ModerateSelank anti-anxiety effects comparable to benzodiazepines
Study confirms Selank provides significant anti-anxiety effects comparable to benzodiazepine treatment, with added cognitive enhancement and no addictive potential.
ModerateSelank increases BDNF in hippocampus and prefrontal cortex
Selank increases BDNF production in the rat hippocampus and prefrontal cortex, preventing ethanol-induced memory impairment and enhancing synaptic plasticity.
