What Is Phenibut?

Phenibut is a GABAergic drug with anxiolytic and nootropic effects. It is used in Russia, Ukraine, Kazakhstan and some other countries as a mood elevator, a tranquilizer, and a nootropic for anxiety. Phenibut is a derivative of the naturally occurring inhibitory neurotransmitter Gamma-Aminobutyric Acid, or GABA. An extra phenyl ring makes Phenibut cross the blood-brain barrier much better than the original compound. [2]

Phenibut was synthesized in the USSR in the 1960s by the Soviet chemist and professor Dr Perekalin. Phenibut was recognized for its brain stimulation and anxiety-reducing effects.

Drug to Calm You Down

Phenibut was used by the Russian astronauts to decrease stress and also to maintain high performance levels. It is a known fact that the cosmonauts of the Soyuz-Apollo Space Project had Phenibut in their medical kits.

Phenibut capsules may have a calming effect in small doses and can improve sleep quality along with other positive Phenibut effects. However please remember that Phenibut is a strong medication that should be only used when prescribed by the doctor. Remember that there are safer Phenibut alternatives to support the nervous system, for example: Selank, Afobazole, Mexidol, Stresam as well as other non-medicational methods to reduce stress.

What are Phenibut Uses?

According to the official Phenibut drug sheet and some human research papers mostly conducted in Russia as well as anecdotal Phenibut reviews, the nootropic is said to be beneficial in case of the following symptoms:

  • Emotionally labile disorders including post-traumatic stress disorder (PTSD) [3;4];
  • Asthenic disorders (lack of energy) [5];
  • ADHD [6,7];
  • Alcohol withdrawal [8];
  • Poor sleep quality [9];
  • Other conditions, characterized by reduced intellectual productivity.

What are Phenibut Benefits?

The ability of Phenibut to combine two opposite effects: tranquilizing and activating – makes it a limelight for those who look for a substance with a calming, yet nootropic action. 

Unlike benzodiazepine tranquilizers that have a depressing effect on the CNS and cause reduced performance and attention, Phenibut is said to be void of such side effects if used moderately and under the doctor’s strict supervision. That is one of the reasons why it is widely prescribed by doctors in former Soviet countries to treat ADHD, hyperactivity and lethargy.

What are the Side Effects of using Phenibut Capsules?

When taking Phenibut, it is important to be aware of the potential side effects. The most common adverse reactions to the drug are an increase in irritability, lethargy, dizziness, and nausea. If Phenibut is used for a long time at high doses, a hepatotoxic effect, including fatty liver dystrophy, and eosinophilia may occur because of the Phenibut liver toxicity.

It is also recommended to avoid Phenibut anxiolytic while driving.

What is Phenibut Dosage?

The most common dosages indicated by the official manufacturer are 250–500 mg, 2-3 times a day. The maximum single dosage is 750 mg. The usual course duration is 2-3 weeks. One pack of Phenibut capsules 250mg contains 20 pills.

It is advisable to refrain from Phenibut high dosages. Consider choosing the low dose to minimize any negative side effects. Besides it is not always necessary to take Phenibut as a course treatment. Please consult your doctor prior to use.

Phenibut Recreational Use Restrictions

Phenibut can be a safe medication when used responsibly in moderation and according to the doctor’s prescription. [10] However, if taken in large quantities for recreational purposes, it is likely to cause euphoria, hallucinations followed by tolerance and severe withdrawal symptoms. 

Other side effects of taking Phenibut high doses include delirium, dissociative effects, and even coma. Therefore, we limit the maximum order quantity to 3 packs of 20 capsules.

Phenibut Contraindications

Individual intolerance to the components of the drug, age below 2 years, pregnancy and lactation, as well as history of severe drug abuse.
