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.

FAQ: 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.

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.

Phenibut Reviews

You can read 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.

Great Company

I have ordered a few times from this company & it is so nice to deal with a company that is very consistent & knows what they are doing. The info they give is clear & there are so many options to choose from to help with whatever you need. Also forgot to mention they ship out orders right away, well at least what I have needed so far. Keep up the good work & consistency! JD

Nice Packaging, works GREAT!

Works great, easy to use/dose. It's seems like Phenibut is getting harder and harder to source in USA. I used to buy it by the Kilo and make my own 500mg capsules (size 00). But I either can't find it in bulk (normal supplier out of stock for a long time), or those that DO have it in bulk, are selling 10-25 Kilo's at a time! It costs too much like that, and I'd never use it all in 10-lifetimes! These tablets are good, easy to dose, and I have found that just ONE does the job for me (and at 250mg the tablet is 1/2 what I took when I made the capsules). Thus I found out that with Phenibut, LESS is MORE! In other words, 250mg works for me with these tablets - works to eliminate anxiety, and help me to sleep all thru the night.

Dear Eric, Thank you for your positive feedback! We're delighted to hear that you've found our Phenibut tablets to be effective and convenient to use. It's great to know that our product has helped you manage anxiety and improve your sleep quality without needing large quantities.

This is the highest quality phenibut you can buy. Unfortunately I have had to go elsewhere because they no longer accept debit cards. I do not buy Crypto, nor do I know how. It's sad to me because nobody beats their product or price.

It helps.

This is something my son uses- he has random anxiety which comes on for no reason. Script meds didn’t help nearly as much as this. Only downside to these are the drowsiness and risk of dependence. Which seems to be true of most everything. So grateful it is available.

Hi Gloria! Thank you for sharing your thoughts and experience with us! We are glad to hear that this product has helped your son. However, we always recommend consulting a medical professional before taking any medication.

Phenibut

Cosmic Nootropics was definitely amazing, checking off all boxes for customer service. The product was just as advertised and priced better than expected. Shipping was quick and seamless. It was my first time using phenibut in about 8 years, and I don’t know what I was expecting. Nonetheless, it was useful to have and well worth trying. I’ll be ordering again in order to experiment with dosing. Overall, well worth the purchase and experience.

Ordering for my first time had a hiccup, however the staff made it perfect. I\'m unable to write a review per my account, via the link sent to my email, but I\'m 100% satisfied. I don\'t know what to expect from phenibut, but it seems to be of high quality! I will be ordering again as I setup a new payment. Do NOT use cashapp, because the fees are so high, they caused my ordering issue. 5/5!

HQ and Legit

I was wondering why some of the reviews were mixed and I thought it was strange considering this is a pharmaceutical grade medicine. I have a lot of experience with phenibut, with F.A.A. and HCl. I do not have a tolerance or use phenibut regularly anymore either. So, after trying this product out, it is a very high quality and a very real and effective phenibut HCl. The negative reviews were more than likely from tolerant users or people who are combining it with other substances that may mask the somewhat subtle effects of phenibut at the lower dose ranges. Some people have body chemistry’s that may mask some of the effects possibly. It takes at least 1g for certain effects to become more apparent for myself. But ideally you don’t want to feel these effects for most practical applications using this substance. The other reviews are trash. Don’t listen to them.

04/17/2024

Hi Mike! Thank you for your detailed and honest review. We are thrilled to hear that you found our Phenibut HCl works great for you! We believe that reviews like yours help assist customers in making informed decisions.
