Phenibut Review: Dosage, Effects & Where To Buy Phenibut

Phenibut for sale

Phenibut was originally created and prescribed to deal with anxiety. But this anti-anxiety medication is now used for far more reasons than dealing with anxiety.

In fact, it’s now used by people as a nootropic, and unfamiliar turn to some, so probably better known as a smart drug. A smart drug allows you to experience better focus, better memory recall, better memory retention, and overall a sharper, faster brain. Perfect for studying, high-stress situations, things like that, especially as you also get the calmness this anti-anxiety medication brings.

But is it really that good, or is it all marketing hype to tell you where you can find Phenibut for sale and convince you to buy it?

Well, in this in-depth guide, we’re going to tell you everything you need to know about using Phenibut, including how to dose it, the effects you can experience from it, the benefits of using it as a smart drug, plus also be straight with you about potential side effects and problems you could face.

What Is Phenibut?

Phenibut was originally designed as an anti-anxiety medication in the Soviet Union during the early 1960s.

It was designed to be a solution to people who are undergoing treatment for various conditions, but who are struggling with focus and calmness to make progress. Its construction helps to deal with the following problems:

  • Depression
  • Anxiety
  • Insomnia
  • Vocal problems (conditions like stuttering)
  • Mental clarity
  • Remaining calm under pressure
  • Faster thinking patterns

It was so good at keeping people calm and boosting their mood and mental focus, that it was actually tested for inclusion in the Soviet space program. Because it worked with low side-effects, cosmonauts would routinely take it prior to going into space, to keep them calm during the most stressful time: take off and exiting the atmosphere. Phenibut is still carried into space by Russian cosmonauts visiting the European space station.

So it’s little wonder that with those properties, and it keeping people calm when they have been blasted off into space, that it has the potential for people without mental health problems to significantly benefit from using it as a nootropic.

How Does Phenibut Work?

Phenibut is constructed to mimic the action of an amino acid gamma-aminobutyric acid (GABA), which works as a neurotransmitter. When GABA attaches to the GABA receptors in our brains, it produces a calming effect.

It also inhibits certain brain signals, which dampens a range of other negative effects. On top of that, it decreases activity within the central nervous system, which is why it has such anti-anxiety (anxiolytic) properties.

But here’s the thing. Although we do make GABA in our bodies, it’s not available from many external sources. In fact, in terms of food, it’s only available from a few fermented sources.

So if we want to boost our GABA levels, then that’s virtually impossible to do through normal ingestion. This is why Phenibut introducing chemicals that mimic this key neurotransmitter has such a dramatic effect.

Phenibut also boosts levels of dopamine.  This is crucial for motivation, happiness, attention, and even smooth physical responses.

Phenibut Effects & Benefits

So what are the benefits of taking Phenibut that a normal person can experience?  Broadly, a good dose of Phenibut will bring the following benefits for several hours:

  • Phenibut will keep you calm and improve your outlook
  • You will experience significant cognitive improvements
  • You will come more focused and motivated
  • You will feel alert and alive

If you have an empty stomach and take a good dose, then the positive effects start to kick in after around 30 minutes.

So overall, Phenibut effects will be to calm you down, get rid of anxiety, raise your mood and beat depression, focus your mind, allow your mind and memory to work faster, and potentially improve your thinking capacity overall.

Put that all together, and Phenibut is a powerful nootropic powder to take (is overwhelmingly available as a powder rather than a pill).

Think about all those positive benefits kicking in an hour before you have a key work presentation. Think about those key benefits kicking in when you are facing a difficult exam or night of intense studying.

Also, think about those benefits if you have social anxiety, and struggle to fit in. Feeling calmer, more lucid, happier, more talkative, can work wonders for people who struggle socially.

Phenibut high

Can You Feel A Phenibut High?

Many people wonder if you can use Phenibut to get high. Just like with kratom, it’s disputed by some people, however, it’s really a case of taking a high enough dose. The people who have never experienced a Phenibut high, just as with kratom, generally haven’t taken a strong enough dose to experience that, a strong enough dose to get to the next level.

At high doses, and we are talking 2000 mg and higher, you could start to experience an increasingly deep euphoric high with Phenibut, one that can also completely diminish your inhibitions. So a Phenibut high is possible, but you really have to be careful with it, because of the high dose and the side effects it can trigger.

However, that hasn’t stopped a lot of people using Phenibut socially, to feel that they are racing, euphoric, anything can happen, but still feeling calm and in control.

At high doses, you will feel a lot more, or at least you will think you are feeling a lot more. You’ll feel more alive, more in tune with yourself and the world around you, you’ll feel more positive, outgoing, happy, and unstoppable.

Correct Phenibut Dosage

Even at a low dosage, the effects of Phenibut can last for a long time. A dose can last as long as six hours. But what actually is the correct dose of Phenibut question. Well, that’s difficult to determine because a lot of the actual research data is in Russian and unobtainable.

However, in the West, doses tend to be within the three following brackets:

  • A low dose is up to 750 mg
  • An average dose is up to 1500 mg
  • Strong doses above 1500 mg
  • An overwhelming dose is around 2500 mg

So people looking to get an overwhelming experience, a Phenibut high, or to really be racing with all the benefits Phenibut can bring, often take up to 2500 mg, sometimes more.

People report that on these very high doses, 2000 mg a higher, it’s a bit like being on a benzo, a bit like MDMA, it can become that overwhelming.

But in terms of being a nootropic, doses of around 1000 mg are often reported as ideal. At that level, you get a greatly enhanced calmness, mental focus and clarity, positivity, and energy, but without it being so overwhelming that you can’t actually focus on that one task you want to.

Phenibut Side Effects You May Experience

Now all these wonderful Phenibut benefits don’t come side effect free. You don’t get to be a better version of yourself, experience happiness and pleasure, without something lurking on the horizon.

The first thing you need to worry about is tolerance. Tolerance is where your body gets used to the dose, and you have to take an increasingly higher one to get the same level of effect.

Phenibut can build up a tolerance very quickly. If you are taking high doses you will quickly build up a tolerance, in a matter of months sometimes. So it’s important that you only take high doses of Phenibut infrequently.

Also, at high doses, once the initial euphoric rush has worn off, Phenibut can be so overwhelmingly calming that it’s a sedative. This is why it is very similar in many ways to kratom.

But to be clear here, Phenibut is prescribed in doses of around 500 mg, several times per day, but with people usually not exceeding 1500 mg.  To get the long-term benefits, you should be kept below this level and make it only a couple of times per week.

The general side effects you need to watch out for include:

  • Agitation
  • Jitteriness and excessive energy
  • Lack of appetite
  • Depersonalization
  • Heart palpitations
  • Fatigue
  • nausea
  • Dizziness
  • Depression
  • Muscle tension
  • Emotional addiction

Now, very few people experience all of those symptoms, and most people will only experience a couple of them at low levels. But if you keep hitting high doses of Phenibut then you could start to experience several of those side effects with an increasing frequency, intensity, and duration.

Using Phenibut With Kratom (Phenibut Stack)

Kratom is actually very similar to Phenibut in many ways. At low doses it’s a stimulant, at high doses it produces a stimulating euphoric high, that starts to tip over into strong analgesia and sedation. So what happens if you use Phenibut with kratom, creating a Phenibut stack?

People using both together in a Phenibut stack report that it creates a synergy, where the effects of both are enhanced in a smooth and stress-free way.

What makes this potentially happen is that kratom interacts with the opioid receptors in the body. This can have the effect of inducing significant calmness, focus, and pain relief.

On top of this, kratom is a stimulant because of some of the alkaloids it contains, which means you are getting calm and pain relief with a boost in cognitive and physical energy levels.

You’ll get the enhanced effects because Phenibut interacts with the GABA-b receptors. Again this deals with calmness, clarity, and enthusiasm. So you’re getting a double dose of calm and focus with a boost of energy because you are interacting with different receptors that deal with similar physical and emotional responses.

However, as you increase the dose, both of these substances have sedative properties. This means overwhelming calmness will tip into sedation more quickly if you use Phenibut/kratom stack, then using the same dose of either on its own.
