Phenibut is a kind of drug that possesses anxiolytic and nootropic properties. Its anxiolytic characteristics give this substance the ability to prevent anxiety and panic making a person relaxed and calm in stressful situations.

Phenibut is called a nootropic substance because of its ability to enhance intelligence, improve memory, concentration and focus by increasing the supply of oxygen to the brain, by promoting the growth of new nerve tissues, and by regulating the availability of hormones, enzymes and neurotransmitters.

Concentration of Phenibut

Phenibut is manufactured from plant cellulose and rice flour and sold in capsule form. It does not contain eggs, gluten, yeast, peanuts and other nuts, fish, shellfish soy and any form of dairy products.

Phenibut Side Effects

Do not drink alcohol or take sedatives and prescription drugs when you are on Phenibut supplementation. You need to consult your doctor before taking Phenibut.

Solubility of Phenibut

Phenibut is completely soluble in water and alcohol.

Customer Reviews

This was a 'just WOW' experience for me. I have read quite a bit on phenibut HCL, but not tried it until now.

It has had an immediate and profound effect on my sleep quality. This is a powerful actor on the chemistry of anxiety and tension. Occasionally I am stricken with "ruminative thoughts", replaying a day's events to the point of distraction, which leads to muscular tension and impaired ability to fall asleep. Phenibut provides substantial relief.

It took a bit of experiment to dial in the dosage for me, I started at 250 mg, I am at 500 mg, every third day. The plan is for use two weeks out of every three.

I would be remiss in not mentioning several things:
READ! There is a lot of research on this substance, no need to re-explore ground others have already covered.
Pay attention to warnings on over use, tolerance, cross tolerance and the possibility of withdrawal symptoms.
Use the least amount of phenibut that will provide the effects you want.

With care and the proper respect for phenibut's potential, this is a great supplement that will provide benefits that others can not.

I have taken Phenibut for many years and this is on par with the highest quality I have seen. I have had it all from the fluffy white power from 1Fast400's old branding, to PrimaForce's overpriced lower potency version. It seems that the suppliers keep dropping this from their selections and I am glad that I found a vendor that ships high quality with reasonable pricing. Since I have used it for years, I take a larger daily dose than some but find that I no longer need anti-depressants or benzo's. I realize that this works on GABAb and as such there is a tolerance and dependence that occurs after several days, but I have never found anything that works so well. Price is less than many generic prescription meds out there and as long as you are aware of the side effects of long term use, I heartily recommend it.

Personally I stack with Noopept and a 5hr Energy once I am work and it takes me through the day alert and focused. Once I wind down after work with the kids, I re-dose before bed and have a restful evening.

The taste is bitter but I usually mix it in some juice or the 5hr at work. I think that the Noopept tastes much worse. Texture resembles super fine grain sugar which I prefer to the fluffy white power.

As for shipping, I ordered on December 1st and although I received an email that it shipped later that day, the Post Office didn't receive the package until 5pm the following day. I will give BS the benefit of the doubt and blame the mail. Shipping from NV was 2 days to KS with a modest cost of about $5. Due to dwindling supply I opted for Priority 2 day but suspect that the free shipping offered at checkout would have been the same.

Overall positive experience with Bulk Supplements and I will continue to order from here. Hopefully they will continue to stock this as many of the previous companies have dropped Phenibut from their product line.

On 12/18/2014 Patrick said...

This is the best quality I've found, exactly what it says. Only problem was a small shipping mistake where it was sent first class mail though i paid for overnight - money was refunded and customer service was prompt and helpful. overall, a great experience - will buy again.

On 12/16/2014 Zack said...

Don't take over a gram your first time! 500mg does the trick for me; major decrease in anxiety, improved concentration in class and other benefits. Buy 50g your first time to make sure its the right product for you!

On 11/3/2014 Zachary Mclennan said...

This powder is one of the easiest I've worked with, scoops nice and easy as compared to, for instance, l-theanine. With 1.5g I notice a nice calm over my body, and no anxiety in situations in which I'd be extremely nervous normally. Very good stuff! I recommend to everybody.

On 10/24/2014 Alex Vasquez said...

I've tried other nootropics without any real psychoactive effects, until Phenibut. I dosed with 750mg, and within two hours I noticed a nice, calm over my body. I fell asleep easily that night, without any hangover the next morning. The Phenibut tastes pretty terrible, but its not bad enough to be off-putting. I recommend a dose closer to 1g, for better, anti-anxiety effects. Careful with high dosages and continued dosing, this stuff has pretty strong withdrawal!

On 10/7/2014 August said...

This is a quality product. It taste pretty bad, but it disolves well. Just mix it with a little water and shoot it down.

On 10/6/2014 Brian said...

I've used Phenibut in the past (prima-force). I'm aware of tolerance and questions of potency surrounding this stuff, but it's not typically an issue for me, as I use 500mg to 1g a week at most, and skip weeks. This helps it to be that thing I can rely on when needed without it being a crutch. It works great for stress/anxiety/social situations where you need to kind of relax but not lose focus or be intoxicated.

I've had the previous 100g supply for over a year, and was running low as I've shared it, so I decided to give this place a try. Package came quickly, as advertised, and seems to be at least on par with the other Phenibut I've tried. The wife was having a particularly stressful day yesterday, and I kindly suggested she try this, and the difference in her mood/anxiety from my perspective was incredible, and we went on to have a lovely evening.

I would recommend this product for anyone with social anxiety over prescription benzodiazepines, but I am not a doctor. YMMV. Please do take care as others have said to not abuse this substance. It's positive effects are amazing as directed and I have not noticed any side effects ever when used as directed.

On 10/4/2014 Faron said...

Pheniwhat? This stuff is very potent and great for anxiety, depression, and a whole host of ills. The taste is quite salty and chemically but it dissolves easily in water so its like drinking a nice big cup of ocean water. Be careful with this supplement and follow the dosage instructions on the pouch as it is such a potent supplement its quite easy to form an addiction. Also BE CAREFUL MIXING WITH ALCOHOL and other psychiatric medication especially benzodiazapines as phenibut can make them poteniate their effects.

On 10/1/2014 James said...

This is the second time I've ordered from Bulk Supplements. I read a lot of favorable reviews online about this company and I have been completely satisfied so far. My Phenibut order arrived with days and it was well packaged. The benefits seem to be just as advertised: enhanced relaxation and longer, more restful sleep. I also ordered a bag for a friend and he gave the product a big thumbs up.

On 9/30/2014 Robert said...

This is my second time ordering phenibut from
I was very impressed with quality and speedy arrival of my order.

Their Phenibut is an excellent addition to anyones mental reinforcement regime! I love the anxiolytic properties and the general well being this supp. gives! Just make sure u cycle off it every 2-3 days with a good 2-3 day break! I noticed amazing results and will continue to order my supps. from this site!

On 9/29/2014 Jon said...

Totally awesome, I love how relaxed I feel when I use this. I haven't noticed any come down or crappy side effects at all. Thanks guys!

On 9/28/2014 sierra said...

this is the real deal fresh and pure , it will left you up when your down, but go by the directions, 500mg. in the morning and 500mg 3 hrs. before bedtime two days out week. that's what works for me , good stuff but be careful with it.

On 9/27/2014 lester said...

Ordered on the weekend, had it by midweek so fast shipping. Everyone told me, "If you get some, but it from xyz." I did and it was good. This time I ordered from bulksupps (here) and it was every bit as good. It really calms my day while improving alertness. I use it 2-5 times per week with no problem. It keeps you regular too! LOL

Thanks bulksupps. I'll just buy from you guys going forward.

On 9/27/2014 samuel said...

I have been taking Phenibut for the last 10 months. The first brand I tried was Primaforce It was a quality product but a lot more expensive than BS brand. Next was Liftmode, good potency, better price but hardened into clumps that had to be broke apart. Bulk Supplements brand is the best I have tried and I dont plan on buying elsewhere.

Phenibut in general may have saved my life. I'm an alcoholic and the severe shakes I had when I tried to quit cold turkey were too much for me to handle I was suicidal. Phenibut took them away and helped me find peace.

On 9/26/2014 Don said...

I have social anxiety problems. I don't take anything for them because benzo's are too strong and everything else doesn't work. Until I found this. It works better then I had hoped for. Almost too good.

On 9/25/2014 Nicky Nick said...

The Phenibut seemed to be of very high quality and indeed was pure phenibut powder. It had a crystal like appearance to it, and was fascinating to look at, so much so that I showed my Mom.

I tried the product and it worked great. One should be careful however and not take it three days or more in a row as you will become addicted.

Anyways, I bought this because my girlfriend is addicted to Xanax and this helps with anxiety as it is a GABA molecule that can cross the blood brain barrier.

If you have anxiety, I highly recommend this along with Picamillon, where you can also add Kava root extract, valerian root extract, l theanine, GABA, Relora, and Holy basil leaf extract to your stack. Overall, Picamillon and Phenibut, both GABA molecules that can pass the blood brain barrier will be most effective.

I hope this helps, and please don't get addicted.

Overall, I was very pleased with ordering from this website. The product came remarkably fast too and shipping was not outrageous. Hope this helps!

On 9/24/2014 Richard said...

Was a little skeptical at first ordering however seeing others have had good success, thought Id give it a try. Started with about 500mg to see what dose would be good for me....2 hours later was alert more uplifted senses seemed lifted . When it came time to sleep well can you say good night fast enough. woke up with a little grogginess but went away fast but was somewhat lifted again in the morning. Good sleep or ?Just take care with amount you take... test first.

On 9/21/2014 lee said...

Honestly, I was hesitant to purchase Phenibut from here as i've been taking it for months now. I've been taking Primaforce brand and now after recieving my order from here I've found it to be A LOT more potent.I also did receive my order FAST... I switched from Primaforce to bulk's phenibut only because the website I WAS ordering it from ( literally took 7, sometimes 8 days for it to arrive on my doorstep. Not only did I find a QUICK shipper but a better quality too.. Fuck yeah.

On 9/17/2014 Joey Mitchell said...

After I received Phenibut I was very excited to try it after reading the reviews and what it claims to do. The first time was great, had extreme focus and my social anxiety was gone. I noticed the recommendation was to take only twice a week, so I decided to do some research and found that you can take it everyday and there should be no side effects. Although even that site recommended to do three days on and two days off to have a forty-eight hour flush. Now I tried this but it seemed by the third day I felt very strange so I stopped but the next two days I had no motivation what so ever and felt almost depressed. With all of what I said I don't want to freak people out just realize that this stuff is very powerful and should not be toyed with. All in all I would say its a great product, with quick delivery, just know its power and use it wisely.

On 9/17/2014 Zane said...

is a good anxiolytic.

On 9/15/2014 Ted said...

This product is definitely top-of-the-line! It is completely pure, dissolves instantly in water, and is inexpensive for the profound effect it can have. I have been a chronic insomniac for most of my life. Sleep is precious and this helps a great deal with occasional use. It can also perk me up early in the day, so double duty on days when I take it. I suggest not taking it close to bedtime and following the suggested dosing written on the package. It's exactly what I expected when I ordered it, and that's important considering the cost of many supplements over time.

On 9/1/2014 Philip Howard said...

I have tried 4 other phenibut suppliers on the market and this is by far the most potent and pure that I have experienced. Bulksupplements will be my go to supplier from here on.

On 8/31/2014 Randall said...

This is a very effective product to treat anxiety. I take it at night, and the effects last me throughout the whole day.

On 8/23/2014 Kevin said...

Couldn't have been happier with the product I received. I have been using phenibut over the last year to treat my insomnia and anxiety. Works perfectly and product is top quality. Was very surprised with with how quickly I received my product! The customer service and product itself was top of the line and I am excited to purchase from again.

On 8/22/2014 Brendan said...

I started with 250mg or 1/4 Tablespoon and then each night added an extra 1/4 T until I found my dose. I take 3- 1/4 T at about 8pm. I sleep like a rock. I am so comfortable and sleepy that I hate to wake if I gotta pee pee at night. So now I have no liquid after 7pm and I sleep a straight 8 hours. Do you realize how priceless this is? There are folks who would give up an arm to sleep like this.Pay attention to your dose and when you find it do not exceed it for a long time.

On 8/11/2014 bert said...

I have a more productive day and sleep better at night. It has a calming effect and I love the service I get with bulk Anxiety....goes away.....I feel normal

On 7/20/2014 mary said...

Very good quality. I use it to relax after a very stressful day. Works like a charm.

On 7/14/2014 Charles said...

Taking Phenibut, I experience deeper sleep, and reduced anxiety, or none at all. Wow, I love it!
I do keep to recommendations on dosage. I am a light weight, so 500 or 250 mg. with a meal works for me.
Excellent product, and prompt shipping .

On 7/13/2014 Harris said...

I've been using phenibut for years and recently found about's great deal on bulk phenibut. The order arrived promptly, the quality is top notch. Phenibut is a great long acting anxiolytic and anti-depressant. When I take it, I find my social anxiety melts away, I feel much more positive and when I'm ready for sleep, I fall asleep quickly and sleep soundly. I recommend this product whole-heartedly.

On 7/10/2014 Cecelia said...

I combine phenibut with l-theanine as a sleep aid. 400mg to 600mg of each taken before bed. Works great.

On 7/7/2014 Curtis said...

Amazing quality pure powder really is pure power. And the shipping was amazingly fast i was really happy with the shipping. As for Phenibut itself is amazing to the 100% Phenibut is truly a amazing supplement to have! Especially with a good quality pure product from BulkSupplements i am very pleased.

On 7/6/2014 Tyler said...

I ordered on 5-6 and delivered on 5-9 using standard shipping. I am pleased with my purchase and I would not hesitate to reorder in the future. Thanks Bulk Supplements!

On 5/11/2014 Tracy said...

In my experience, 500mg - 1000mg taken within one individual day/night period - but not taken more frequently than twice per week - is useful and effective.

On 5/7/2014 Jeremy said...

Take around a gram and wait a few hours. You'll feel relaxed and social. The effect is comparable to a pharmaceutical--this is not placebo-induced snake oil.

Very good stuff. Very recreational.

Careful to not use too much, though. Too much of good thing usually ends up being not as good.

That being said, give it a try if you're interested in relaxation!

On 5/6/2014 Haig said...

this product is a powerful anxiolytic. It put me in good humor and I felt at ease. The only negative side effect is nausea. Please be careful and do not take high doses. There are online reports that suggest that one take it in 3g increments.


.5-2g is plenty. 6g resulted in 36 hours of incapacitating nausea. Vomiting every hour. Low doses do not produce this side effect but are still therapeutically effective.

On 5/6/2014 Evan said...

This product (phenibut) is so excellent. I have been using this product with recommended dosage and have been having excellent results. Fast deliver, excellent service.

On 5/4/2014 Scott said...

This is an outstanding sleep aid. It also serves as an antidepressant, and an anxiolytic . In Europe, and in Russia it is a prescribed psych medication. If a person is to take it for the first time he or she must abide by the following rules to prevent an uncomfortable overdose effect:

1) take a very small dose
2) wait at least three hours for it to take effect

It has the effect of a benzodiazipine (Valium) with much less danger. Sleep well.

On 3/31/2014 John said...

This is a pretty amazing product. I'm not used to dietary supplements that have a such a noticeable effect. I took about a gram of this and felt really relaxed, watched the new Cosmos, and had the most incredibly restful night of sleep in ages. I commonly wake up really early in the morning and can't go back asleep but this stuff is seriously incredible. I woke up feeling like a million bucks--that's not hyperbole, Plus, I had some really vivid, pleasant dreams. Obviously, this isn't something you're supposed to use too often but it's amazing something so effective can be had without a prescription and without causing a positive result on pre-employment drug tests.

This is a truly remarkable substance but I'd advise strong self-control with it and of course don't drive or operate heavy machinery. Using this stuff recklessly will earn the ire of the FDA and ruin it for the rest of us.

On 3/21/2014 Greg said...

Fantastic supplement for relaxation and confidence. BulkSupplements always delivers quality orders in a very timely fashion.

On 3/8/2014 Davis said...

This product help me relax and go to sleep for a few hours, easily. Recommend to buy this product if you cannot sleep properly.

On 3/5/2014 Charles said...

Because I work the night shift; I use phenibut for sleep. Phenibut is the most potent substance, for sleep, that you can get without a prescription. It is plenty powerful. Bulk supplements produces a great product. I would recommend this Company's product to anybody. (This is a Russian invented chemical. I would say that it is as much genius to medications as their AK line of rifles is to guns),

On 3/2/2014 John Leggett said...

Very potent. Best Phenibut product I have tried, and at a good price. I still can't get over the taste though. It never gets better.

On 3/1/2014 Dean said...

I've not tried phenibut before, but I found this supplement to be quite effective as an aid to relaxation and as a sleep aid. Purchasing from was very efficient, and the product arrived quickly. I plan to buy supplements from this site in the future and will recommend it to my friends.

On 2/26/2014 George said...

I have tried this product a couple times when my stress level is high and it causes it to calm down. It helps me relax. I am pleased and will purchase more in the future.

On 2/20/2014 Gwen said...

Product arrived within a few days packaged in a very sturdy resealable pouch. It was exactly as I expected and I am very happy with the results. I've told a number of friends and coworkers who use supplements to check out Bulk Supplements web site. Thanks and keep up the good work.

On 2/17/2014 jvs said...

So I've tried phenibut from 3 different sources. One was obviously cut with who knows what and the second was very good. Unfortunately the quality of the last shipment from the second source was noticeably less than usual. Since I already get magnesium and l-theanine from bulksupplements I decided to try their phenibut and I'm glad I did. It's at least as strong as my previous source if not stronger. They don't make any claims as to the strength/purity of their phenibut, unlike most other companies, but I'd say that it's about the strongest you can get and for a good price. Don't hesitate to give it a try!

On 1/30/2014 Dustin said...

This is a great supplement for those who experience problems sleeping and move swings. I have MS and suffers from mood swings and this is more effective than St, John's Wort.
