What Is Phenibut?

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.

What is Phenibut Used For?

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 and Effects?

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.

Are Phenibut Capsules Safe to Take?

Phenibut can be a safe medication when used responsibly, in moderation and according to the doctor’s prescription. [10] When taking Phenibut, it is important to be aware of the potential side effects and contraindications.

Refrain from using Phenibut in these cases: individual intolerance to any components of the drug, age below 2 y.o., pregnancy and lactation, as well as history of severe drug abuse. It is also recommended to avoid Phenibut anxiolytic while driving.

Can I order Phenibut to Australia?

We highly recommend refraining from purchasing Phenibut if you are from Australia. Phenibut is officially banned in Australia and will likely be stopped by local customs. In this case, we cannot be held accountable and will not be able to refund or reship your order. This may also concern countries such as Hungary, Lithuania, France or Italy.

Is Phenibut the Right Drug to Calm You Down?

Phenibut capsules may have a calming effect in small doses and can improve sleep quality along with other positive Phenibut effects. Phenibut was even used by Russian astronauts to decrease stress and maintain high performance levels. It is a known fact that the cosmonauts of the Soyuz-Apollo Space Project had Phenibut in their medical kits.

What Are Phenibut Alternatives?

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 Recreational Use Restrictions?

Phenibut is known to be used by some people for recreational purposes. However, such misuse poses serious health threats. 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.

What Are Phenibut Reviews?

You can check some Phenibut Reddit reviews. There are also Phenibut Russian reviews which you can read via google translate. Please note that individual reviews from customers and Phenibut users may contradict the views of the CosmicNootropic team and are given for informational purposes only.

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.

What are Phenibut 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.

Phenibut

I’ve used Phenibut for years, and as another reviewer stated, this is legitimate Phenibut HCL; it is an excellent product to help ease anxiety and boost self-confidence and mood. In addition, it always seems to help me with my sleep quality. Do your research. Onset is 2-4 hours, peaks about 4-6 hours afterward, and can stay in your system for about 24 hours. Respect this product, follow recommended dosages, and USE SPARINGLY to maintain efficacy and to avoid tolerance and dependency (I use one dosage 1-2 times a week at most). Lastly, I would like to add that I’m very impressed with Cosmic Nootropics products and outstanding customer support. Thank you
