Phenibut, also known as β-phenyl-GABA, is a central nervous system depressant with both anxiolytic (anti-anxiety) and nootropic (cognitive-enhancing) effects. It is chemically similar to the neurotransmitter gamma-aminobutyric acid (GABA), which plays a crucial role in reducing neuronal excitement and thus alleviates anxiety and stress. Phenibut was developed in the 1960s in Russia and has been used there for various conditions, including insomnia, anxiety, depression, PTSD, and alcohol withdrawal syndrome.
Phenibut is not approved as a medication in several countries, but it has been available online as a dietary supplement. It is often sought after for self-treatment of social anxiety and as a cognitive enhancer. The drug has gained popularity as a nootropic, with many users reporting improvements in sleep, reduced anxiety, and enhanced cognitive function.
However, there are significant concerns regarding the use of phenibut. It has the potential for abuse and can lead to dependence and severe withdrawal symptoms if discontinued abruptly. Withdrawal symptoms can include anxiety, agitation, insomnia, and in some cases, more severe symptoms such as hallucinations and delusions. There have been reports of life-threatening conditions and fatalities associated with phenibut use, with some users falling into comas.
