Can You Get ‘High’ On Phenibut? | A-Z Guide

Can you get ‘high’ on Phenibut?

You’ve probably heard about the effects of Phenibut — but does the ‘Phenibut high’ really exist? Yes, but not in the way that you might typically think of.

Phenibut is one of the best nootropics out there right now for creativity, and it’s also an amazing support for people who feel socially anxious. It makes you feel relaxed and social, which is why it’s part of my recommendation for having a great night out sober — if you’re trying to cut down on your alcohol intake. It can even help with sleep.

And yes, it really can also give you a ‘high’ feeling… but it’s a lot different from most other drugs.

In this guide, we’ll give you the scoop on everything from what the Phenibut high feels like, how much Phenibut to get high, Phenibut recreational dosage, the Phenibut half-life, and more.

Let’s dive in.

This is not medical or legal advice. This guide is strictly for entertainment purposes only. Always consult a medical professional before consuming any nootropic and always abide by the laws of your country. Please read my disclaimer page, too.

What is Phenibut?

Before you understand what the Phenibut high is like, you have to understand a bit about what the nootropic is and how it works.

Phenibut, also called β‐phenyl‐γ‐aminobutyric acid, is a chain of amino acids [1]. The chain looks chemically similar to one of the main neurotransmitters that help our brain send and receive signals through our nerves: gamma-aminobutyric acid or GABA [2].

GABA’s job is to inhibit excitability in your nervous system. It basically tells your nerves to stop firing off messages. This is useful because you don’t want your nerves to be always firing. You want them to take a break every once in a while. So Phenibut basically works like GABA, binds to the same receptors, and reduces the amount of brain activity. It basically chills you out.

Phenibut also is responsible for increasing dopamine and serotonin levels [3]. Dopamine and serotonin are both other neurochemicals and are both involved with making you feel good. Dopamine, especially, is often considered a part of the “reward center” of the brain. Together, these are responsible for the huge boost in your mood that Phenibut creates.

Phenibut Effects

So Phenibut basically increases your GABA activity and also your serotonin and dopamine levels. The effect? Basically, you chill out while also feeling great. Phenibut effects include,

  • Reduced anxiety [4]
  • Feelings of euphoria [5]
  • More sociability [6]
  • Better sleep [4]

These effects are why Phenibut has been used by many countries as medication to reduce anxiety and improve sleep [1, 7].

These effects are one of the reasons why many individuals consider Phenibut the best “social” nootropic available.

Phenibut Side Effects and Safety

I’ve got a whole article on Phenibut side effects, so I’m not going to get into that in huge detail here, but there are some side effects that you have to think about when you’re taking Phenibut.

They fall into three main categories: actual side effects and allergic reactions, interaction effects — which will only happen if you’re mixing Phenibut with alcohol or something else, and withdrawal effects — which only happen if you become dependent on Phenibut.

Side Effects

These are rare but sometimes happen. The big ones are [8, 9, 10]:

  • Drowsiness
  • Nausea
  • Irritability
  • Headache
  • Sedation

Much more rarely, side effects can sometimes also include [9]:

  • Motor incoordination
  • Hangover-like symptoms
  • Loss of balance

Allergies are also possible and could lead to itchiness or rashes.

Want to avoid these? Don’t take too much of it at a time. Start with a low Phenibut dosage until you see how your body reacts. Then you can increase gradually. Your risk of getting these side-effects goes up when you start taking more than 1 gram of the stuff a day.

Interaction Effects

These are the effects that happen when you mix Phenibut with other substances. Since Phenibut works on the GABA receptors and reduces excitability in your body, you should not mix it with other substances that have similar effects. That means, don’t mix it with [1, 11]:

  • alcohol
  • benzodiazepines
  • anticonvulsant medications
  • antipsychotic medications
  • barbiturates

If you mix it with these, you might exaggerate the effects of either. That could be dangerous, especially if you’re taking high doses. It could cause,

  • Severe drowsiness
  • Nausea
  • Vomiting
  • Lowered blood pressure
  • Impairment of the kidneys
  • Delirium or psychosis [12]

Basically, Phenibut is a downer, so don’t take it with other downers. If you just take Phenibut by itself, you’ll be fine.

Overall, Phenibut is a safe nootropic.

Dependence and Withdrawal

Again, I have a huge guide to Phenibut withdrawal, so check that out if you’re looking for more detailed information.

But Phenibut does have the ability to get people dependent on it [13, 14]. It’s not a problem for most people, but you should be aware of it since it is quite different than other nootropics — Modafinil, for example, has very, very low risk of creating dependence.

How do you make sure you don’t become dependent on Phenibut? It’s easy.

  • Don’t take too much. Make 1g at a time, 2g a day the absolute maximum. 500mg is better to start.
  • Don’t take it too often. Use it 1 to 2 times a week at most.
  • Cycle off if you think you’re becoming dependent. Take a month off every once in a while.

If you learn how to take Phenibut properly, you won’t have a problem with dependence.

Phenibut High | The Basics

Okay, now the good stuff. Tell me more about that Phenibut high!

So the Phenibut ‘high’ is real, but it’s a lot different than what you might be thinking. You’re not going to get “wasted”, you’re not going to have any hallucinations, and you’re not going to lose control of your mind.

Are you actually ‘high’ then?

Well, it depends a bit on what we mean by ‘high’ in context. Science is a bit behind in terms of providing a definition for being high, but I like what one Quora user said about what a ‘high’ was [15]:

“To simplify, “getting high” is about altering the body, mind, and emotional state, bringing you to a place of “feel good” or euphoria.”

Phenibut can get you a ‘high’ like that:

It alters your emotional state and gets you to a place of euphoria. There are no hallucinations, no being unable to walk, and no feeling like the music is caressing your face. It’s different than that, but you’re definitely still high.

Does Phenibut Get You High?

Yes, the effects of Phenibut can definitely feel like a high, but it’s not like cannabis or other drugs. It’s a nootropic, one that individuals use for social purposes.

Here’s what you can expect:


At first, you’ll notice a feeling of euphoria, which is the dopamine. You just feel good, like you’re buzzing with positivity. It’s a bit like the buzz from alcohol, but without the fuzziness. You just feel great and are free of anxiety.

Think of it like the great feeling you get after working out, except you’re not exhausted and your legs don’t hurt the next day.

More Social

You also feel more social. It’s like all those worries you have about what other people think of you just melt away. You’ll feel great about going up and talking to strangers about random things.

You know that feeling of excitement when you meet someone that you just click with? Where you’re witty and interesting and just at your best? The Phenibut high is like that. One study actually found that people’s emotional intelligence was boosted from Phenibut, which may be why people talk so much about the great social effects that it has [6].


While there’s a clear change in how you feel, you don’t get fuzzy. You can talk fine, you can think clearly, your vision is good, and you can reason. You also don’t have any of the mobility issues that alcohol gives you — there’s no stumbling home on Phenibut.

This buzz leaves you thinking clearly — better than normal, even. You can actually get lots of work done while you’re on it.

One thing is that you probably shouldn’t drive. While Phenibut usually doesn’t mess with your ability to drive, it can cause drowsiness. So I’ve seen some caution about using it and then operating machinery. It would probably be fine, but I guess better safe than sorry.


Your Phenibut high can start anywhere from the first 30 minutes and builds for a few hours.

Phenibut lasts quite a while, too, because the Phenibut half-life is pretty long. The Phenibut half-life is how long it takes for half of the Phenibut dosage to be eliminated from your body. It’s about 5 hours, so that means if you take 500 mg, 5 hours later there will still be about 250 mg in your bloodstream.

The high part usually lasts around three or four hours, and the effect lasts even up to 18 hours after that. There’s also a kind of afterglow which can last up to 24 hours after that.

Is There a Phenibut Hangover?

I don’t usually experience a hangover. If you’re an anxious person, you might notice your anxiety coming back. Some people have also reported feeling a bit of a headache or a foggy brain, although I haven’t had that. Even if you do, it’s way better than an alcohol hangover.

One thing is that you may feel some negative emotions start to come back. Be careful that you don’t try to get around those by taking more Phenibut — you want to stay away from getting dependent on it.

How Much Phenibut to Get High?

This is the critical part: what’s the Phenibut recreational dosage?

Your Phenibut dosage really will depend on you, your particular chemistry, and the kind of Phenibut effects you want. I’ve got a Phenibut dosage guide that gives way more detail, but this is the gist:

  • 250mg to 500mg is a safe starting dose that you’ll feel, but may not get you high.
  • 500mg to 750mg would usually be enough to get you high.

Phenibut Tolerance

Keep in mind, you can build up a tolerance to Phenibut fairly quickly. Tolerance is where your body gets used to the effects of Phenibut, so what might cause you to get high one day might not have much of an effect the next day.

Be careful not to make that an excuse to continually take more and more. You should be careful to not take over 1 g in a single dose, or over 2 g in any single day.

Instead, give your body a break before you use it again. If you notice it’s not having an effect after you took it a few times, wait a week or two before trying again. This will give your body to get back to normal.

Phenibut Dosage Guide

Here’s my simplified Phenibut dosage information for different effects you might want:

For sleep

This amount great if you want to make sure you’re getting a full, deep sleep [16]. Beginners can even take a little less:

  • 500mg to 750mg
  • split into 1 to 3 doses
  • an hour before food

For Anxiety

If you’re just trying to take the edge off your anxiety, you can take a bit less:

  • 250mg to 500mg,
  • split into 1 to 3 doses,
  • an hour before food

Phenibut Recreational Dosage

This is a good amount for those people looking to try out the Phenibut ‘high’ for the first time:

  • 500mg to 750mg
  • in 1 dose
  • an hour before food
  • 1-2 hours before you go out


This won’t get you high, but it can give you some great effects like lower anxiety and a little boost in mood:

  • 50mg to 250mg
  • in 1 dose
  • an hour before food

Where to Buy Phenibut Online | 2020 Guide

Phenibut is legal, but it’s difficult to find in person. You pretty much need to get it online.

My favorite supplier for Phenibut is definitely LiftMode. They’re currently the only company I would recommend. Here’s why:

  • Their prices are super reasonable.
  • They just have a great reputation and aren’t sketchy (lots of online suppliers are, so be careful).
  • Their product is pure and not cut with anything weird. They provide a certificate of analysis on their website so you can be sure it’s legit.
  • They have a legitimate payment system with convenient payment options (including Bitcoin) and they respect your privacy.

I’ve tried some others but wasn’t impressed. LiftMode is the best.

Yes, but not like other drugs. If you want to get messed up, or you want a reason to make bad decisions and not remember them, Phenibut can’t help you.

After utilizing nootropics for the better part of a decade, I realized the potent results these products produce -- with regards to productivity and cognitive enhancement. Soon thereafter, I became obsessed with finding the premier smart drugs on the market. Then using them to improve my life. When I'm not devouring everything I can about nootropics and the science behind why they work, you'll find me traveling around the world or in the gym.
