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. 
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.
Even though Phenibut capsules may have a calming effect in small doses and can improve sleep quality along with other positive Phenibut effects – please remember that Phenibut is a strong medication that should be only used when prescribed by the doctor.
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 Phenibut 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) ;
- ADHD [6,7];
- Alcohol withdrawal ;
- Poor sleep quality ;
- 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.

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.

Phenibut Recreational Use Restrictions
Phenibut can be a safe medication when used responsibly in moderation and according to the doctor’s prescription.  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.
Individual intolerance to the components of the drug, age below 2 years, pregnancy and lactation, as well as history of severe drug abuse.

Doesn’t feel like the phenibut I’ve taken before.
This product doesn’t have the same quality of phenibut I’ve taken before.
Dear Eva, We're sorry the product didn't work for you. For most nootropics, the effect can be varied for different people. It strongly depends on the personal conditions, so we always recommend consulting a specialist before taking any medication. All products in our store are original with high verified quality.
Danielle O.Verified Buyer
Not sure if it works
Each person is different, but I’ve tried one, two and three tablets at a time. I didn’t feel more relaxed or less stressed. The only thing I noticed was I started to get some headaches the week of me trying it. Maybe it can help somebody else.
Hi Danielle! We are very sorry that the product did not work for you. For most nootropics, the effect can be varied for different people. It strongly depends on the personal conditions, so we always recommend consulting a specialist before taking any medication.
Vladimir S.Verified Buyer
Amazing 🤝 thanks you so much.
Kelly L.Verified Buyer
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.
Dear Kelly, thank you for sharing your experience, we are glad you are satisfied with our product!
Apostolos D.Verified Buyer
Great quality, fast shipping time, 100% recommend
Dear Apostolos, thank you for your feedback! 🧡
Alan B.Verified Buyer
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.
Dear Alan, thank you for your review! But please rest assured that we sell only original products that are legally sold in Russia and quality of each product is controlled by the producer. And effects of the product may vary depending on your health condition, dosage, age, etc.

This is a very high quality product. I know the dose amount I am getting and it has been a great benefit for me when I am suffering from insomnia. The customer service at Cosmic nootropic is unparalleled.I have always had very quick responses and when I have place an order it is received in a timely fashion. I wrote this review of my own volition. No promise of a free product was offered so I am genuine in my comment here.

Jeremy L.Verified Buyer
What happened to Cosmic Nootropic???
I have been ordering from Cosmic since 2019 and have always had a good experience. However, I've had issues now with the my last 3 orders. In particular, right now I have an outstanding issue with an order I placed A WEEK ago. I paid for it same day, and have yet to receive shipping information. I have emailed support with a screenshot to follow on it, and have gotten no more than a "we'll check into" reply. So here, a week later I'm still waiting with no shipping confirmation and no reply. What happened to this company that the service has gone downhill to such a horrible extent?
Dear Jeremy, thank you for finding a moment to write to us. Unfortunately, we are experiencing some troubles with our payment options at the moment and since we use a third party company as a provider, sometimes problems occur that we have no control over. :( We deeply regret that you feel this way about our company. Please be assured that we are committed to providing quality products and services to our customers and are doing our best to resolve every issue. We have already contacted the company multiple times and we will update you as soon as they do. We appreciate you taking the time to share your thoughts with us, and we once again sincerely apologize for any inconvenience caused.

David T.Verified Buyer
Amazing anxiolytic for my ADHD brain
Has been a great help to help me come down after the heavy stimulant days of final exams / heavy lifts with harsh stims. I also love the stimulating element of this compound that allows me to function better as I have ADHD. Great product
Dear David, thank you for sharing your experience! Glad to know that our product works for you :)
Best phenibut out there!
This phenibut is top quality! I purchased from another vendor. I had purchased a bottle years ago which was fine. I repurchased and felt like I was being poisoned. Not only was their quality poor and ineffective but it felt there was something in it that was very toxic to the body. I refused to use it. This is a big name company. Did some research and found Cosmic nootropic! Incredible customer service. Answered questions withing a day. I was a bit confused with shipping processes. Great company will definitely order again. Pam
Dear Pam, we're beyond happy to know you were satisfied with our products and service! Hope to see you as our customer again!
Chuck S.Verified Buyer
After reading lift mode phenibut quality has been going down, I decided to try to find pharma phenibut. It was delivered quickly in the US and works well.
Hi Chuck, thank you for your feedback! We're glad that you're satisfied with the product and delivery. :)
Pharma Grade Phenibut
After trying Phenibut from other sources online, I will definitely say this Phenibut feels the best and the quality is outstanding. I use it on occasions when I need to perform and it does not disappoint. The delivery didn't take long (came from America) and there was constant tracking updates. Definitely going to order from Cosmic Nootropic again :). I would only recommend taking it now and again, for me no more than once or twice a week max.
Hi Sam, thank you for sharing your positive experience with our product. We're thrilled to hear that it exceeded your expectations! We value your satisfaction as our customer and hope to continue serving you in the future. :)
Stan D.Verified Buyer
Did not get my order , it's been 2 months!
I dknt know what happened but they never shipped me my order. I got the DHL slip, but it says that DHL never got the package!
Dear Stan, We are sorry for this unpleasant experience. The thing is, our US warehouse is operated by a 3rd party company, so we were not aware of the situation. You should've just emailed us so we could solve the issue and either reship or refund your order. Please check your inbox and let us know what option you prefer :)
