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.

Not worth the price

Took a low dose to start, didn't feel anything. Couple days later took a much larger dose and same thing happened, no effects.

02/04/2024

Dear Marco, We're upset to know Phenibut did not work for you the way you expected. But as for most nootropics, the effect may vary depends on your health condition, that's why we always recommend consulting a specialist before taking any nootropics.

Reliable retailer

I have ordered multiple times from Cosmic Cosmic Nootropic and have received superb service at each step in the process. They provide you with confirmation and tracking from the warehouse in Russia quickly. They also communicate well if you have questions. I have already recommended them to a friend and will continue to recommend them in the future with confidence. Shipping from Russia to the US takes longer than I would like it to take, but that means I simply have to plan more carefully when ordering. I believe my first order arrived in just under 30 days during the holiday season. My second order arrived in approximately two weeks. I use phenibut for sleep. It’s the most effective product I have ever used for this purpose. It has greatly improved the quality of my life, and it is reassuring to have a reliable retailer for it.

01/26/2024

Dear Benjamin, we're thrilled to hear you've had good experiences with our store! Thanks for recommending us to a friend. We understand shipping time can be a bit lengthy, but we're glad it hasn't deterred you. We appreciate your confidence in us and are delighted that our product has improved your life. Sleep well!

Phenomenal product. Shipping is expensive but the overall service and packaging is great. I also like the tablets in this better than capsules or powder of other brands. I would however like to see the Noofen formulation offered, and preferably at a reasonable price.

Pretty good. Helps relax and with sleep.

Some people suggest this is a drinking alternative, and that could be but it does not give the euphoria of drinking. However it does help me relax, wind down and sleep... and takes the edge off. It's similar to a CBD gummy to me. Picamillon is very similar. Both picamillon and phenibut are GABA analogies that can readily pass the blood brain barrier, unlike GABA supplements on their own. You should not drive a vehicle or operate heavy machinery if you should take this... it's for relaxing and going to sleep. And for that it works better than GABA . That's my 2 cents anyways. Do your own research.

Phenibut

I've used Phenibut on and off for years to help with staying asleep. This brand has no effect whatsoever. Not sure if it's just not Phenibut or if it's incredibly under-dosed. It's hard to write anything positive about a product that doesn't work.
