The Ultimate Guide Phenibut

Phenibut is a central nervous system depressant that’s actually been hijacked by the nootropics communities around the world because of the cognitive benefits it brings. In this guide to Phenibut, you’re going to learn everything you need to use it safely and successfully.

It can be a controversial supplement, and although it’s legally prescribed in some parts of the world, mostly it’s illegal to buy and use. In this review, you’ll learn where Phenibut is legal, alongside the other key things you need to know: dosage, effects, how to stack it with kratom, and side effects to watch out for.

All that, plus I’ll talk to you about the two online stores that I’ve bought 100% pure Phenibut from. Unless you can buy guaranteed 100% pure stuff, then you have no idea what you’re putting in your body, which is why it’s essential you always buy it from recommended vendors.

What Is Phenibut?

Phenibut is a central nervous system depressant that’s been used since it was developed in the 1960s to help people with anxiety disorders. Anxiety and insomnia are the two conditions it was developed to help with.

So this stuff was invented in the Soviet Union, and is still prescribed in the old Soviet countries (primarily Russia, Ukraine, Latvia, and Kazakhstan) routinely for the following conditions:

  • Depression
  • Alcoholism
  • Motion sickness
  • Anxiety and stress
  • Social problems
  • verbal and physical ticks/stuttering

Despite widely being prescribed in a few countries around the world, and being used illegally in many others, there’s actually very little known about how it works. That may sound nuts, but the mechanism of action, how it works, is still not fully understood.

Russian animal studies are the primary studies conducted on their use. A lot of the research is old though and in Russian, so we don’t have much idea of what was found.

But the studies we do have access to show significant successes. For example, in one study, adults with anxiety disorders were given 1000 mg of Phenibut each day. In 73% of the cases, the anxiety was totally removed and they were able to function normally again. This was only a short 30 day study though.

What we do know is that most of the studies have been on anxiety disorders, and for that, it has been successful in treating it. In fact, it was used by the Soviet space program to help astronauts cope with the anxiety of lift-off and re-entry, and is in fact still included in the first-aid packs of Soviet space missions.

But all that is not the main reason why people are using Phenibut. Where it’s available illegally, it is used as a smart drug, a nootropic, because it can offer significant cognitive benefits alongside its ability to calm people down and remove anxiety.

Phenibut works as an analog of an amino acid in the brain commonly known as GABA. It’s an inhibitory neurotransmitter. That means it naturally helps to dampen down activity in the central nervous system. The more GABA that attaches to the GABA receptors, the calmer and more focused you will be.

You may have even seen GABA supplements for sale. But it really has a problem crossing the blood-brain barrier to bind to GABA receptors in the brain, making them virtually useless, which is why you need something which can achieve this, and Phenibut does that.

As well as being a GABA agonist, it also helps to stimulate the dopamine receptor. This is the key neurotransmitter that deals with motivation and reward. It makes you want to achieve more, and it makes those rewards more pleasurable. This is the basis of what can cause a Phenibut high.

Where Is It Legal?

Phenibut legality is a complex subject that we can’t cover in this guide properly.

Let’s talk about the USA as an example though.

In the USA it’s an unregulated drug. That means it’s not been legally authorized for prescription or use on humans. So it can’t be legally sold or possessed. But that doesn’t stop it happening as that’s rarely enforced.

In Canada you can legally import and possess it, but only if the total amount does not exceed 90 day supply. As there is no true definition of what a daily dose is, I have literally no idea how they would work out what a 90 day supply was.

If you’re worried about the legality of Phenibut where you are, please check your local laws before you attempt to import it. You are very unlikely to be arrested or charged, but you will definitely have the Phenibut you tried to import destroyed.

How To Use It Safely

When it comes to learning how to use Phenibut, it’s pretty straightforward because it’s available as a pill or powder.

We will talk about correct dosage in a moment, but all you need to do is dose it to start feeling the effects in as little as one hour, with onset beginning from 30 minutes after consumption on an empty stomach.

The reason for using Phenibut will also matter in terms of when you use it and how. Insomnia you’ll obviously take in the evening, for cognitive benefits you’ll take it an hour before you need it. If you’re looking to curb anxiety, you should be doing it before you enter the situations you’re trying to cope with.

Phenibut dosage

Dosage Guide For Beginners

Let’s now take a look at Phenibut dosage ranges. Unfortunately, it’s a clouded topic because although it’s widely prescribed in the old Soviet Union countries, there’s no real consensus on how much, or how often, you should dose Phenibut.

But what we do know is that 1000 mg is a very high dose. More regularly, doses seem to be 500 mg or less, with a once or twice daily dose of 200 mg something very frequently mentioned.

To help with writing this, I bought some Phenibut for review purposes. I’ve used modafinil a lot, but never Phenibut because of the addiction problems if you’re not careful.

But the Phenibut for review that I bought was definitely 100% pure, and I started with a low 200 mg dose. I didn’t have any side effects, and I did get some significant cognitive benefits, as I will now explain.

Phenibut Effects & Benefits

Phenibut effects and benefits can be substantial. Unfortunately, though, there haven’t been a lot of human studies done on cognitive performance-boosting abilities using it. One study on youngsters suffering from extreme ADHD showed that 700 mg per day for one month gave significant improvements in attention spans, self-control, and memory modulation.

So, at a low dose, what I found, and what others seem to confirm, is that you can get the following key benefits:

  1. Phenibut definitely lowers anxiety. Even at 200 mg per day, you will feel chilled out for several hours. Onset is quite rapid, and it lasts for quite some time before slowly tailing off. You feel calmer, more confident, there are no worries in your mind, and social anxiety just drifts away.
  2. Phenibut does deliver cognitive enhancements. For me, I felt more stimulated, better mental clarity, and I also felt more generally motivated to do stuff. I could work for longer, focus better, and I just produced more.
  3. It can also help with sleep if you are suffering from insomnia. It helps to shut down your active mind, which is one of the reasons why it’s been prescribed for ADHD users because it helps them with switching off their brains and focusing.

Having said all that, it is dose-dependent, and it will depend on who you are. As a smart drug, cognitive benefits don’t always happen. Especially if you take a higher dose, that calmness, that sedation, can be so predominant that you actually feel dumbed down mentally.

How Long Does It Take For It To Kick In?

Some people can get into trouble taking Phenibut because of the length of time it takes to kick in. For most people onset starts within one hour of taking it, but for others that can be as long as three hours. This has caused some people to overdose by taking a lot more than they should, and as a central nervous system depressant, this can create consciousness problems. So you need to be aware of the fact that it can take several hours for Phenibut to kick in fully.

Phenibut And Alcohol

Phenibut and alcohol can be used together in a complimentary way. They are both GABA agonists, so they do work in synergy to create an incredibly relaxed and confident state. However, on the downside, they are both CNS (central nervous system) depressants. Drinking lots of alcohol with a high dose of Phenibut can cause increasing sedation.

This combination can also produce a slow heartbeat and shallow breathing, in combination at extreme levels this can lead to a loss of consciousness, and on rare occasions death. So by all means mix Phenibut and alcohol in a moderate and sensible way, but topping up alcoholism with Phenibut can be potentially dangerous.

Lots of people do successfully use Phenibut and alcohol at the same time to create a synergy that works very well. Because Phenibut and alcohol are both GABA agonists they do work in the same way. Together, they can enhance feelings of calm, confidence, happiness, and loss of inhibitions. However, on the downside, they are both depressants.

This means they can both create emotional depression, but they are also central nervous system depressants. CNS depressants at high doses can lower heartbeat, breathing, and induce a lessened consciousness. In extreme circumstances, this can lead to breathing stopping. Use alcohol and Phenibut together only in moderation, and never heavily/in an out-of-control manner.

Stacking It With Kratom To Achieve A “Phenibut High”

A classic Phenibut stack is to take it with kratom. These substances work on different receptors in the body, which can create a synergy that is incredibly powerful. As you now know, Phenibut activates GABA receptors which help to calm us down, focus our minds, and can even lead to an increased desire for risk and reward situations.

Kratom is a partial agonist of the opioid receptors. But it does a similar thing, especially red kratom: it calms down, focuses the mind, makes us feel good. Put together, you’ve got something very potent for calming you down. But too much together and you’ve also got a potent sedative.

It is possible to get a high euphoria feeling. This is thought to be because higher doses release a ton of dopamine which makes you feel fantastic. A real rush of happiness, desire, and drive.

Kratom can also achieve this through high doses becoming full agonists of several opioid receptors. Put together you can get a phenomenal Phenibut high. But it can lead to deep sedation, and won’t create nootropic effects, quite the opposite in fact.

To find out where to get pure kratom from, click here to read a detailed guide to the best kratom vendors in the USA. I will just say though that if you just want to get your hands on the best kratom powder out there, then Coastline Kratom is the best place you can start.

Possible Side Effects & Problems

If you’re thinking of using Phenibut, then you have to be aware of the potential side effects as in some people they can be significant.

At large doses, in some people, Phenibut can cause breathing problems. It induces shallow breathing. If you stack it with kratom this can be enhanced. So do not ever take very high doses of both, especially if you have a chest condition.

Also, you should never take it with alcohol, benzodiazepines, or GHB, as they can also act as a strong respiration depressant.

Generally, Phenibut side effects that you could experience are:

  • Breathing problems
  • Dizziness
  • Nausea
  • Balance problems
  • Fatigue
  • Tingling electric shock feelings and the nerves
  • Headaches

But the most likely worst side effect you could get is Phenibut addiction. If you’re sensible, and you’re only dosing small amounts every few days when you need a cognitive boost, or you need to deal with anxiety, you should be fine.

If you are hammering 500 mg or more every single day, then over a few months you could develop tolerance, which can lead to dependency. Phenibut is apparently a real bitch to get off if you get addicted, so please don’t go down that road. Tolerance can also occur in a few weeks, so make sure you only use it 2-3 times per week.

Where To Buy High Quality Pure Nootropics

The conclusion of this Phenibut review is that it has some positive traits. Personally, I found it brilliant for focusing on getting work done. The effects lasted several hours even on 200 mg. It was noticeable, it was productive.

It can really help with social anxiety, as long as you take small doses infrequently. It can also help to sharpen up your cognitive skills, focus your mind, and create mental and emotional clarity. Used (very) occasionally at higher doses, you can feel brilliant and have a fantastic time, Phenibut high that is memorable and pronounced.

But you have to be aware of the side effects and respect them because this stuff is not something to be taken lightly. When it comes to finding where to buy it, the big problem is getting real Phenibut in the first place. A lot of places sell junk that’s not pure.

But there are two places which definitely sell 100% pure and guaranteed Phenibut. They publish independent lab purity reports as well, as you can see that their stock has been independently verified:

  1. is the first place that sells a genuinely pure product. 50 g of Phenibut HCL powder costs just $20. Even at 500 mg per dose, that’s 100 doses. So it’s dirt cheap, but please use it sparingly to avoid dependency.
  2. is another fantastic source of all sorts of smart drugs. They sell pure Phenibut in capsules, which is unusual because most places tend to just sell the powder. 60 capsules, each of 250 mg costs $39. That’s a total dosage of 15 g. Capsules are far more expensive because of the extra steps to make them, but they are incredibly convenient as you not having to mess around weighing powder and then trying to consume it.
