Phenibut HCl (fenibut, phenybut) is a derivative of the natural neurotransmitter, GABA. GABA is not a nootropic neurotransmitter and actually has inhibitory qualities which can produce tranquilizing and anxiolytic effects.  It was first developed in the Soviet Union at the A.I. Herzen Leningrad Pedagogical Institute under the leadership of Professor Vsevolod Perekalin during the 1960s.

    I absolutely love it. Caution! Do not do too much of it, because the hangover will be worse then alcohol. What I do is use 1-1.5 scoop first thing in the morning when I wake up on empty stomach (no calorie drink) wait about 2 hour before meal. Then maybe in about 7 hours another dose. Also, do not lay on the bed, because that will put you to sleep. Lastly, I heard it not wise to take it right before the bed, because the weakness will still appear after waking up.

    Like another reviewer, I bought Phenibut as a substitute for Gabapentin. Its advertised positive effects are accurate.
    I especially have noticed greatly-improved sleep when I take it before bedtime. Also, it’s largely able to eliminate my anxiety for 8+ hours when taken early in the day. This is awesome when I know I have a long day of working and/or studying ahead of me, as my anxiety usually reduces my general productivity quite a bit. About 1 gram of phenibut, combined with a cup of coffee every couple hours, ensures I’ll have a great day.
    Addicts should be wary of this drug, however, because daily use can easily lead to dependence and withdrawal.

    Loved it, this is exactly what I was looking for. Keeps anxiety at bay for the day and helps as a perfect sleep aid at night.

    Love, Love and Love this product. I only use it once every other week, I take 3 grams on an empty tummy first thing in the morning, have a cup of coffee and I wont eat for at least 2 hours after taking it with water. Whenever I am feeling low, bummed out, down or depressed I take this and with-in the first hour I feel normal, happy, calm and just good. Highly recommended… I would not use it more than once or twice a month and no more than 2-4 grams. Enjoy!

    Start SLOW cause this stuff is very, very clean and the active dose/effects varies -immensely- person to person! I’m a 180lb man, very experienced with this kind of thing, and anything more than 0.5-0.7g (2 level scoops) blasts me into a state well beyond my ability to function while making the experience much less (not more) fun. I’ve watched much smaller people do multiple grams (6+ scoops) of this stuff and claim they feel “relaxed but not buzzed.”
    Its definitely worth mentioning that this is much more like a prescription drug than a recreational one – excellent for getting a functional/silly, pleasant/erotic and engaged/restful state of mind or treating something like insomnia or anxiety. In other words, this works ideally for maintaining a state equivalent to 1-4 drinks over the course of a day or two…if you’re looking to go into “what did I DO last night?!” territory these aren’t the droids you’re looking for.
    CAUTION: The half-life of this stuff also varies person to person. While my understanding is most people have more or less completely metabolized their dose in 24 hours, it takes my body 50+ hours before I stop feeling it. Discover your own rate of elimination and plan accordingly.
    Also, I can definitely see the potential for an unregulated habit of this stuff to get wayyy out of hand. Make a dose schedule and stick to it (I do it generally 1-2 times/month, with a strict 1/week limit). Remember, this is a GABAergic! Google GHB withdrawl if you need to gain a healthy respect for the implications of GABA receptor down-regulation. If you begin to experience withdrawal symptoms, you should drop everything and work on an exit strategy (which ideally involves suffering cold turkey, progressively smaller doses if that’s not possible). If you can’t or won’t follow these rules, you will have a very, very bad time and would do well to avoid it altogether.
    All and all, if you have a proper respect for it, this is an immensely useful and powerful tool.

    Great stuff! Very effective GABA activator and many times substituted for benzos. Great help with anxiety and sleep quality. May become somewhat addictive if abused. Goes nicely with Theanine imo. My girlfriend loves it!

    I’m fairly experienced with phenibut and take it for panic attacks and generalized anxiety disorder. Anywhere between 4 to 6 scoops a day which is probably about 1.5 to 2grams.

    With that being said it’s a great product in helping my symptoms. I’ve been panic attack free for over three months now. Tolerance does build to this so just something to be aware of.

    My first times trying it produced a sense of relaxation, heightened sexual arousal, and a lack of anxiety that is always racing in mu mind. This supplement takes care of all thar. I’ve been able to maintain the same dose while achieving medicinal benefits. So, just because you feel like you need more you probably shouldn’t take more.

    Takes about two hours to kick in but when it does you’ll know. Treat this supplement with respect and you’ll have good results. Not to mention I’m sleeping a lot better than I ever was. It doesn’t mess me up like alcohol or hard drugs which is why I like it. For those of you who suffer from anxiety and need a solution this is a good fix. Take it from someone who suffered for a while. Cheers.

    A tangy Nootropic that makes you downright frisky

    Phenibut is an ideal social smart drug for 2014 Jonathan, but I’m not sure if it would have been for say 2008 Jonathan. Now I’m very mindful, especially in social interactions; I’ve trained with technology like Dual N-Back and the emWave2 to be very present. I’ve actually spent the majority of this year completely sober, see my article about partying sober for +6 months in South America’s #1 vice city. Five or six years ago was a different story, I drank quite a bit (my cocktail of choice was Patron Redbull), smoked cigarettes and used recreational drugs from time to time – I was kind of your average intoxicated douchebag. Phenibut is a pretty subtle effect, you would have to do a lot to get something resembling the mindset you get from alcohol or MDMA. If I had done Phenibut 5 years ago, I don’t think it would have satisfied my hedonic set point, I would have probably been pretty bored with it. Now it’s awesome though, it gives me an extra boost of social confidence free of intoxication.

    Phenibut is a a gabergic drug, please see my other video specificity on the mechanisms of action and studies that have been done on Phenibut.

    I felt very social and frisky on Phenibut… I would describe myself as unfiltered, I found myself doing silly things, like making a tower out of cups and a paper airplane and saying smart ass stuff to my friends.

    I can tell when it kicks in because I enjoy music a lot more, for example…
    Not long ahoI walked into a bar here in South America that was blasting annoying Colombian folk music. I’m not drinking alcohol I don’t know how long I can hang out here and listening to this twangy latin music blaring out the speakers.
    Maybe 30 minutes later a singer came on and started singing salsa songs and it was awesome. I was able to genuinely enjoy the music sober that I usually can’t stand.

    If you are the kind of person who works soul destroying hours, puts in +10 hours a day grinding and then you have a social commitment or a date and you have trouble transitioning to that social mood, consider Phenibut.

    I found I need to do about 3 little spoonfuls to get the desired effect, for me this feels like about two and half beers on an empty stomach for about 3-4 hours.

    This 50 gram bag costs less than $25 dollars so it’s a pretty awesome value compared to alcohol. I would do about a gram each night, so at that rate it costs less than a dollar night and you have no productivity robbing hangover the next day.

    It has a nice viscosity and absorbs very equally in water and actually has a nice tangy taste, unlike a lot of smart drugs you could actually drink it leisurely.

    Finally, sleep is awesome on Phenibut, I always slept a little extra on it, if you want to be able to go out have a super fun night with your friends in a loud place, then go home fall right asleep and wake up feeling really well rested.

    If I have a couple of really stressful days in row where I’m spending +8 hours a day on the computer tackling big problems or projects, it really effects my sleep, it takes me an extra 60-90 minutes to fall asleep. If I do about 750 milligrams it makes me just relaxed at the end of the day and I can fall right asleep.

    I highly recommend this product. They had a decent delivery time, and the Phenibut was great quality!

    Helped my sleep tremendously. No side effects in the morning either.

    Tried Phenibut as substitute for Gabapentin, prescribed off-label for sleeplessness due to working several years on night-shift. While I cannot swear to any noticeable “buzz” it without question helped me sleep. Dreams are vivid, and I awake rested but with less of a hang-over than with Gabapentin. I take 1000-1500 mg, mixed in water. Tastes like sour-gummy-flavoured water! Kinda nice actually. I also took a dose and had a couple of beers on a rare sunny winter afternoon a couple of weeks ago. Best day I’ve had in months! Again, I can’t definitively say there was any particular “buzz” associated with it, the way I have heard some claim, but I felt real mellow and fine. My wife tried it as well. She felt nothing at 500 mg but said she got a nice mellow feeling from 1000 mg. Like anything, it works differently for different people. As with other PeakNootropics products, I recommend their Phenibut.

    definitely works as advertised… more of a powdery consistency rather than the salty consistency from other vendors.

    be careful! its a strong one!
