Phenibut is a type of Nootropic – a class of supplements that exhibit the ability to improve cognitive processes, leading to better memory, focus and mood.
Almost all of the nootropics used today were developed in Europe, and Russia was one of the biggest players in this research.
Phenibut is considered to be the first Russian nootropics ever developed. This supplement was designed at the I.M. Herzen Leningrad Pedagogical Institute USSR and the Institute of Experimental Medicine, Academy of Medical Sciences USSR.
The leader of the team was a Professor V. V. Perekali who was interested in developing compounds that could reduce anxiety in astronauts without impairing their mental faculties. Phenibut was the result of their extensive research: a mental performance enhancer that had anxiolytic properties and could support a balanced state of mind.
Phenibut is a synthetic derivative of the naturally occurring brain chemical known as GABA. This neurotransmitter is released by your brain cells when prolonged periods of excessive neuronal activity are detected, protecting neurons from the over-stimulation that can cause anxiety.
Phenibut’s structure is essentially a GABA molecule bonded with a Phenyl ring. This slight change in structure is responsible for the increased effectiveness of Phenibut for crossing over the protective barrier separating the bloodstream from the brain (blood-brain barrier). GABA supplements are not able to cross the blood-brain barrier to any great degree, however the slightly different structure allows Phenibut to cross and act in the brain similarly to endogenous GABA.
Phenibut is to this day used as prescription drug in Russian to treat General Anxiety Disorder, Social Anxiety, Depression, and various forms of insomnia and other sleep disorders. In the rest of the world, you can buy Phenibut in bulk legally at health food and specialty nutrition stores. It does not require a prescription in countries such as the USA, Canada, Australia or the UK. At this time the FDA has not approved Phenibut as a drug to prevent or treat any conditions.

How Phenibut Powder Works
One of the main goals in the development of Phenibut was to create something that was able to easily pass through the blood-brain barrier. Any supplement designed to affect the brain must be able to cross over this barrier to enter into the central nervous system.
For example, GABA supplements do not work very well for improving mood and relaxation because they cannot cross this barrier. With the slight modification in chemical structure that Phenibut features, it can cross this barrier quite easier.
Once in your system, this supplement acts as a natural precursor to GABA. In other words, it actually breaks apart, losing the Phenyl ring and turning into GABA. This is believed to be the primary method for influencing a number of its calming effects upon the brain and the body.
It can then bond with GABA receptors on neurons that are firing at an excessive rate, thereby curbing the neurological processes that ultimately lead to feelings of anxiety.
The Phenibut Experience
What does taking Phenibut feel like? This is one of the most common questions we see people asking before they decide to purchase bulk Phenibut.
The best way to determine this is of course to try it for yourself; how Phenibut affects other people may not be representative of its effect on you. That being said, it is always reassuring to hear from other users about their positive results.
Many individuals have reported their actual Phenibut experiences on different forums and online review sites. Most of these experiences indicate some type of increase in overall mood, akin to a feeling of well-being and comfort. Other users have stated that it is like a ‘warm wave’ coming and overtaking them.
Some users say that it offers benefits for sexual performance enhancement while others say that it helps them to clear their mind and focus when studying or working.
Phenibut is primarily taken as a supplement for anxiety. Since it works to raise the levels of GABA within your brain, this usage makes sense. By limiting the over-excitement of neurons, it can have a calming and relaxing effect. This serves to eliminate stress and reduce anxious thoughts/feelings.
Many Phenibut users also report that it helps them with cases of social anxiety, allowing them to improve their communication skills and gain more pleasure from social interactions. Some studies have hypothesized that Phenibut may even lead to the reduction of symptoms of depression, although more research is needed into this area.
Another effect that is quite interesting regarding Phenibut is that it can potentiate, or improve, the effects of tranquilizers, narcotics, and neuroleptic medications. Some evidence also supports this supplement having an anticonvulsant effect.
This can have a negative effect as well, producing too much sedation if used improperly. For this reason, you should not combine Phenibut with alcohol or other anxiety medications.
There has been a lot of interesting research into using Phenibut supplements as nootropics. Phenibut is thought to improve memory, learning capacity and problem solving ability. Some reviews online say that it makes their minds feel sharper and heightens the speed of their thoughts.
Studies also show that it can make it easier fall asleep, stay asleep, and wake up feeling more refreshed and rested. In clinical trials, patients given Phenibut spent a longer time in deep sleep states like REM.

Buying Bulk Phenibut Powder
Phenibut is actually one of the cheaper brain supplements around, especially when buying it in powder formation.
You can get 50 grams of Phenibut powder for as little as $23.99. With an effective dose of 500 mg, that means your price per daily use is only 24 cents.
If you’re looking for bigger discounts on bulk Phenibut products, some US vendors will sell you as much as 1 kilogram at a time which could conceivably last for well over a year of consistent use.
The most important consideration when buying Phenibut in bulk is that there have been some low quality products marketed in the past. If you have ever seen reviews with people saying that this nootropic had little effect on them, chances are they unwittingly bought a fake product. Pure Phenibut is incredibly powerful and you will almsot definitely feel effects.
Always check for a COA when buying nootropics in bulk and make sure that other users have had positive experiences with the company. A good way to verify this is by reading reviews posted on third-party websites and hearing from other customers.
Phenibut HCL vs. FAA
There are two different forms of bulk Phenibut powder that you can buy currently: the hydrochloride salt and the free amino acid.
Most vendors will sell Phenibut hydrochloride (HCL) as the default option. If you do not see see a specific form of Phenibut denote on the label, you can assume that the product you are buying is the HCL version.
Phenibut F.A.A. refers to the free amino acid form of this nootropic agent. It contains only phenibut (99.5% purity) with no other ingredients or chemicals.
Phenibut hydrochloride is made by reacting Phenibut FAA with hydrochloric acid. This makes the compound more stable, water soluble and it crystallizes easily. While it has the advantage of being easy to handle, it contains less of the active ingredient than the FAA form.
Phenibut hydrochloride is composed of 83% phenibut molecules and 17% HCL molecules. This means that a 100 mg dosage of the FAA form contains 17 more mg of Phenibut compared to the HCL form.
It is interesting to note that if consumed orally, Phenibut FAA will get converted into the hydrochloride salt in the stomach. It may require a slightly smaller dosage, but given the addition cost of the FAA form there is little to no advantage for oral administration. The main difference will be the less bitter taste of the Free Amino Acid.
The main reason to purchase Phenibut FAA is for sublingual (under the tongue) use. While Phenibut HCL can cause irritation of mucous membranes and may result in a burning sensation if taken sublingually, the FAA version can readily cross the mucous membrane and is not an irritant.
Some users claim that taking Phenibut sublingually produces better effects and requires 1/3 of the standard dosage used of the HCL bulk powder form. This would make it more cost-effective.
However, note that there are no research studies available on sublingual use of bulk Phenibut powder and information on this form is largely based on anecdotal evidence. Pharmacokinetic studies are needed to evaluate the comparative bioavailability of using Phenibut Free Amino Acid sublingually.
Side Effects & Safety Precautions
Before you run out to get Phenibut online, it is important that you are aware of some of the possible side effects with this supplement. While Phenibut is considered safe and is usually well-tolerated, in some instances there have been reports of increased sweating, drowsiness, reduced appetite, and restlessness.
If you are taking Phenibut on a daily basis, you can quickly develop a tolerance to it. Only use it on an occasional timeframe and allow your body the chance to reset every few days. A five day on, five day off schedule has been suggested by some users, while other users suggest even longer off times.
When stopping your Phenibut usage, it is recommended to slowly decrease the dosage over a few weeks to prevent any withdrawal symptoms. Never combine Phenibut with sedatives or other drugs as they can interfere with each other.
It is always a good idea to check with a doctor or qualified health care professional before adding a new supplement to your routine. Your doctor will be able to determine the best dosage of Phenibut powder for your personal physiology and determine if it may negatively interact with any other supplements or drugs you are taking.
