phenibut

Phenibut is a psychoactive drug that acts as a GABA-B receptor agonist and, to a lesser extent, a GABA-A receptor agonist. It was developed in the Soviet Union in the 1960s and is used medically in some countries for anxiety, insomnia, and other conditions. Phenibut is also available as a dietary supplement in some parts of the world, though its regulatory status varies significantly by region.

The effects of phenibut are often described as anxiolytic, sedative, and mood-lifting. Users report reduced anxiety, improved mood, increased sociability, and enhanced cognitive function at certain doses. However, side effects can occur, especially at higher doses or with frequent use. These may include drowsiness, dizziness, nausea, and fatigue.

Tolerance and dependence are significant concerns with phenibut. Regular or high-dose use can lead to physical and psychological dependence, with withdrawal symptoms manifesting upon cessation. These withdrawal symptoms can be severe and may include anxiety, insomnia, tremors, and even psychosis. Due to the potential for dependence and withdrawal, medical professionals often advise caution with phenibut use and recommend a gradual tapering schedule if discontinuing use.

The legal status of phenibut is complex and varies by country. In some nations, it is a prescription-only medication, while in others, it is available without a prescription or is outright banned. This lack of consistent regulation contributes to its availability through various online vendors and its use outside of medical supervision.
