What is Phenibut?

Phenibut is a synthesized version of GABA, the major inhibitory neurotransmitter of the brain. The added phenyl group allows the synthesized GABA to cross the blood barrier.

Phenibut was created in the Soviet Union in the 1960s to help professionals working in stressful environments to better handle difficult situations without lowering cognitive performance.

It’s usually sold as Phenibut HCL or FAA. Phenibut HCL is the salt form of Phenibut and Phenibut FAA is its free amino-acid form. Phenibut acts on the central nervous system in a similar way to antidepressants like benzodiazepines, GHB or barbiturates.

Phenibut is most commonly used as a nootropic, anxiolytic and as a sleep aid. People who have taken Phenibut say that they have experienced:

A combined feeling of mild sedation and mild stimulation.

An increased sense of well-being.

Lower anxiety and increased sociability.

Improved focus, alertness and mental clarity.

Enhanced music appreciation.

Increased sexual drive and performance at low doses.


Is Phenibut safe?

Although generally considered safe with no side effects when taking decent doses (1000-1500mg), it does create addiction and withdrawal if used every day for a medium to long period of time.

That’s why it’s important to cycle use and preferably only use it every other day. Withdrawal symptoms may include headaches, difficulty falling asleep, anxiety and tiredness.

Although these symptoms are in no way life-threatening, they can be unpleasant. A good way to stay safe with Phenibut is to take breaks between periods of use and not let it fall into daily habit.


Is Phenibut legal?

Indeed, it’s safe, but is Phenibut legal as well? You’ll have to check to see if it’s legal in your region. In Russia, for example, you need a prescription for it.

Here in the US, it’s legal and sold as a dietary supplement and available to buy on Amazon, Walmart and many other online stores. This is proof that Phenibut has established itself legally in America. Major companies like these would certainly not risk their business by selling black market products.


Phenibut HCL vs FAA

Phenibut is usually found in two forms. Phenibut F.A.A. is the free amino-acid form of Phenibut and its purity is the highest due to not being combined with anything else. Phenibut HCL is the hydrochloride salt form of Phenibut obtained by mixing Phenibut FAA with hydrochloric acid.

Phenibut is mostly sold in HCL form, with the chemical composition of 83% Phenibut and 17% HCL. The advantage of Phenibut HCL is that it’s very soluble in water. However, due to it being a hydrochloride salt, it has a metallic and rather unpleasant taste. It can’t be taken sublingually or nasally because it damages tooth enamel and irritates the mucous membrane.

Phenibut FAA is the purest form of Phenibut with an almost neutral pH, making it suitable for sublingual administration. It has a bitter taste, is fairly soluble in water and comes in the form of a white powder. It’s two times less dense than Phenibut HCL and slightly more potent.

When taken sublingually, Phenibut FAA can be up to three times more potent than Phenibut HCL. Sublingual administration of Phenibut FAA is often preferred among users also due to the fast onset of effects.


How to take Phenibut?

Phenibut HCL is highly soluble in water, so you can drink it with water or lemon juice. You can also add honey to make the drink a bit tastier.

You can do the same with Phenibut FAA, yet for a fast and obvious “kick”, keeping it under your tongue will do the trick.

Another way of taking Phenibut FAA is to place the desired amount in a small spoon and empty it in the back of your tongue. Swallow it directly or use water or any other liquid to down the Phenibut. The amino acid form of Phenibut (FAA) has somewhat of a sweet taste and leaves a sour aftertaste after being swallowed.


Phenibut dosage

Determining how much Phenibut to take largely depends on your own body weight and what you want to get out of Phenibut. Dosage greatly influences effects.

Lower doses of 250 mg – 400 mg produce mild calming effects, better mood and increased sociability.

Some people compare the feeling felt on lower doses of Phenibut to 250 mg of Xanax, though the feeling is a bit different.

Low doses also produce mild mental and physical stimulation, whereas higher doses accentuate the sedating effects of Phenibut.

If you’re aiming for a more noticeable effect that can be compared to a “high” state of mind, a dose of 750 mg – 1500 mg will do the job.

If you’re a first time user, start with 750 mg or even lower. Phenibut typically lasts around 6 hours, though its half-life is long, hence the reason why the effects will wear off gradually over a long period of time. You can take two doses of 750 mg or one 1000 mg – 1500 mg dose once in a day.

Whatever you do, don’t take more than 2000 mg in a day. Side-effects like extreme drowsiness, residual next-day sleepiness or pupil dilation are much more likely to occur at higher doses. Stay safe, start low, and raise the dose gradually.

Mixing with alcohol may be unwise, especially if you’ve taken a moderate or large dose of Phenibut. Drinking a pint of ale on a low dose of

Phenibut is safe, though even then you shouldn’t drive, operate heavy machinery, go swimming or other actions that you wouldn’t normally do after consuming alcohol.


The Phenibut high: Myth or reality?

Phenibut is an interesting substance because it’s a downer with “upping” properties. It’s basically a depressant with stimulating effects.

Large communities are present on the web (Phenibut Reddit or and most users reviewing Phenibut were impressed with its potency. It’s one of the few nootropics that, if consumed in large doses, will get you high.

Phenibut can be dangerous if taken in large doses (over 2 grams) and it can be addictive if used daily. That’s why you should cycle use by skipping days and take prolonged breaks every few weeks.

Some people say that Phenibut and Xanax are similar in effects, but that’s quite far from the truth. While it does relieve anxiety as effectively as Xanax, a low dose of Phenibut won’t impede cognitive abilities and it won’t prevent memory formation.

In fact, a low dose of Phenibut has noticeable positive effects on focus and mental clarity. This means that you’ll be able to stay focused for longer periods of time, which is great for productivity.

Students can greatly benefit from Phenibut due to it being a great sleep aid, even after the main effects have worn off. It greatly improves quality of sleep, which definitely helps for next day’s productivity. People who take other cognitive enhancers like Adderall or Modafinil will find going to sleep much easier.

Phenibut makes music sound better by enhancing your appreciation to details. The “background noise” generated by your brain is blocked, thus allowing individual sounds to be more obvious.

Another great thing about the Phenibut high is its sexual side. Phenibut boosts libido and sexual performance, meaning that it will make you and your partner enjoy sex more.


Choosing the best Phenibut vendor to buy from

You may be asking yourself: “Where can I buy Phenibut?” or “Which is the best Phenibut vendor?”. There are many websites where you can buy Phenibut from, yet some will offer you better quality, customer service and faster delivery times than others.

Generally, choosing the best Phenibut vendor should be done according to reviews. Of course, both positive and negative user reviews can be faked by vendor associates and competitors, respectively.

Nevertheless, they should still be taken into account, although with a pinch of salt. Another thing to take into account when choosing the best Phenibut vendor is the site aspect and grammar.

A shady looking site should definitely be double-checked and if the grammar is off, then you should skip to the next option.

Shipping policies are also important, especially if you’re living outside the US. You should also look at the refund policy and make sure that they offer a refund in case the Phenibut doesn’t arrive.

Everything stated is common sense for any e-commerce store, though some may be easily overlooked by anyone looking to make a quick purchase.


Where to buy Phenibut online?

While there may be lots of places to buy Phenibut online from, there are some reputable Phenibut vendors that guarantee fast delivery, quality products and responsive customer service. What’s more, these vendors sell other stimulating nootropics that can make your Phenibut experience more enjoyable and productive.

Lift Mode is one of the biggest online nootropic vendors that sells Phenibut and a wide range of other nootropics and supplements. They offer competitive bargains for bulk orders, free shipment for orders over 25$ and an awesome 90-day money-back guarantee in case you’re not satisfied with your product. sells quality Phenibut, Noopept, Adrafinil and many other nootropics. groups its nootropics according to the effect that you want to experience, which makes it easy for beginners to choose the right nootropic for their purposes. The online Phenibut vendor offers free shipment for orders over 50$ (US) and 200$ (International).



Wrapping it up

Phenibut is a truly remarkable smart drug that can greatly improve your overall mood, sleep quality, productivity and sex life. It’s quite safe as long as you’re not irresponsible and know that the right measure will bring you more pleasure.

Phenibut can be taken recreationally, for the pleasant Phenibut high, and as a productivity aid due to the clear-headed and relaxed feeling generated by lower doses.

“Phenibut HCL vs FAA” is a subjective matter that depends on what matters to you. Phenibut HCL is less “tasty” but more water-soluble than Phenibut FAA, that has a sweet taste when ingested and a sour aftertaste.

Phenibut FAA is the best Phenibut type for a person who places importance on potency and taste.

Choosing the right Phenibut dosage depends on what you want to get out of it. An ideal recreational dose is considered by many to be one gram, yet many people claim to be satisfied with less.

Choosing the best Phenibut brand largely depends where you’re buying from. When looking for the best place to buy Phenibut, price shouldn’t be a factor. As with most supplements on the market, you get what you pay for. Rather than focus on price, look for reviews regarding the vendor’s reputation and reliability.

As good as it may be, remember to not use it daily. You’ll build up tolerance and you won’t get a lot out of it.

One last thing..

Make the most out of the experience by having a positive mindset!
