What Symptoms Should I Expect From Phenibut Withdrawal?

What Is Phenibut?

In the most basic terminology possible, Phenibut is classified as a “relaxant“. If you’re worried about Phenibut being a “dangerous” street drug, you’d be way off base. Instead, Phenibut provides an increase in alertness, cognitive processes, memory retention and an increased drive of motivation. You’ll feel great, be mildly euphoric, and drastically reduce your anxiety. This might sound fantastic- and while it is- it’s important to use caution when implementing any supplement into your diet. Phenibut is one of a very select group of drugs that provides motivation, clarity of thought, energy, and focus. Phenibut is the only racetam (or smart drug) that doesn’t actually make you more energetic, it actually helps you sleep. Because Phenibut is a stimulant, your body does form a mild dependence, resulting tolerance, and “hang-over” from this supplement. It’s typically taken in .5 – 1.5 gram doses, and often surprises people how well it fits into their normal routine, with normal substituting of other substances to prevent the buildup of a tolerance. Additionally, there are some medicines that should not be taken in conjunction with this nootropic- like carbamazepine, oxcarbazepine, and other MAO inhibitors that enhance drowsiness.

Phenibut is considered a wonder drug by some. The pioneer of social exquisiteness, spectacular study skills, a complete lack of anxiety or nervousness, and also some of the best sleep that you’ve ever gotten from a dose of medication. Phenibut is a curious racetam in that it doesn’t react like most other smart drugs that make you jittery, anxious, or excited- instead it makes you calm, focused and relaxed.

Many countries (especially Russia and Europe) prescribe Phenibut as a very safe and very effective sleep disorder medication, as well as to promote lucid dreaming, fight depression and nervousness, and open to open up the world so that people can enjoy it more. Many believe that it has the same properties as other Nootropic substances that are often compared to this product, and which also have effects such as:

  • Improving memory
  • Boosting attention span
  • Maximizing focus and concentration
  • Helps with decision-making processes
  • Even effective for those with memory/cognitive development problems

Some reports even suggest that Russian cosmonauts take it up into space with them, and have had Phenibut as part of their astronomical first aid kit since the early 70’s. Because we understand how this substance works, we can also shed some light on how it affects the brain, the side effects associated with Phenibut, the possible hazards, the potential benefits, and the withdrawal information. It’s important to stress that under normal dosing conditions, Phenibut can be used with little to no side effects. Most adverse side effects are related to hallucinogenic psychosis of those who are trying to catch a buzz off of this product (as some recreational users do- responsibly). It’s difficult to accurately track ALL of the details about this substance, simply because it is classified as a supplement by the food and drug administration, and has been used widely for many thousands of years. What is important is that Phenibut is an all-natural substance that works to increase memory, boosting concentration and mental energy to give you calm feelings of inner-peace and well-being. Derived from supplements that create an anxiolytic (sleep promoting) effect, this derivative of the brain neurotransmitter GABA, responsible for many different processes in the brain. Users of different experience levels will experience different effects.

As an affordable, effective anti-depressant, Phenibut is no more dangerous than any other mood altering substance (benzos or otherwise) that provides effective relief for the debilitating conditions associated with insomnia, restlessness, and anxiety. Many users would rather suffer mild (when used properly) side effects of a generally effective anti-depressant mood improving substance than take more regulated substances. It works in a very similar fashion, however, delivering relief to the brain’s neuro-receptors where they need it the most. Anyone informed about GABA substitutes would know that this substance has a more difficult time passing through the blood-brain barrier than other substances, but the developers of this supplement provided a phenyl group molecule that helps the body more readily absorb the benefits of improved GABA, which is more effective than unregulated GABA production, giving you the same effects of a naturally receptive brain in a bio-available formula that easily transports the substances you need to your central nervous system After binding to neuro-receptors, Phenibut gives you the relief that you need when you need it most- especially to those that suffer from prolonged anxiety, stress, or nervousness. Because it turns off the receptors for excitement, arousal, and stress/anxiety, Phenibut practically “comes to the rescue” to those who need it the most, giving users relief that they need to feel great, get some sleep, and go on with their life like never before.

Because Phenibut has such a large number of highly devoted users, we felt it necessary to answer any and all questions regarding this highly useful supplemental substance, it’s effectiveness for treating depression, it’s overall usefulness against social anxiety, and even its ability to relieve nervousness and social anxiety. We highly believe that anyone already relying on different psychoactive drugs research Phenibut to see if it is right for you. Many of those suffering from debilitating conditions have reported significant improvements from the integration of racetams like Phenibut, especially for increased focus and concentration.

In this extended article that highlights the details surrounding the smart drug, Phenibut, we’ll provide the answers to questions that many have regarding this substance.


Phenibut was first discovered by a scientist named V. Peralkaline in the USSR in the 1960’s. It wasn’t highly developed for several years, but is still sold today as one of the first neuropsychotropic drugs. It was discovered in a naturally occurring process years ago, and works to provide many excellent effects of other drugs without negative side effects. Initially developed to improve brain function, many developers have found that it stacks well with other ingredients of other nootropics, decreasing stress and improving mood along with a boost to your mental function.

How To Use This?

Phenibut is exceptionally easy to use. All you have to do is take a normal dose (between 250 mg-1000mg) every day, later in the day to prevent possible lethargy. Often, people taking this supplement report feeling the effects much longer than similar GABA type agonists, meaning that users will want to refrain from taking more than one Phenibut within a 4-6 hour period, even if they didn’t feel anything, to avoid possible overdoses.

What Will I Feel When I Take This?

When ingested (which is the most effective way to take Phenibut) users report feeling extreme confidence, comfort, and relaxation. Many report feeling immediately “at ease”, reporting that it felt like a load of bricks had been taken off their shoulders. Many reported feeling “lighter” and “happier” in day to day activities, because they’re getting better, more restful sleep, and feel more composed, serene, and less worried about day to day activities. Unlike their counterparts, those who use Phenibut reported feeling better within a few days, while some forms of medication take months to see solid results. This supplement has received a bad “wrap” on online forums for being particularly dangerous when only larger doses (which are clearly marked and labeled) pose the actual dangers. Anything can be lethal at the right doses.

How Long Does This Last?

Many users report the positive benefits of Phenibut lasting for months while taking the same does. Even then, as human tolerance develops, dosages only have to increase in very small amounts. While Phenibut is not recommended for lifetime use, it is useful in many situations when anxiety is at its worst or when facing a stressful, anxious situation. Because of the immediate reaction of Phenibut, it is often used as a recreational drug to catch a buzz similar to alcohol. Because the effects are subdued and often very natural-feeling, many instantly feel relaxation from the supplement. Phenibut withdrawals aren’t life threatening or overly severe. Most cases involving “coming-down” from an overdose last about a week, and users are more or less “fine” after their incidents. Many actually report feeling “relieved”, “euphoric,” and “at peace” after their experiences. There is a little bit of controversy regarding how long it takes to “kick in”, how long it stays in your system, and how you will react to it. Most recall feeling a nearly instantaneous calm and relaxed feeling after only taking the recommended dosages. You’ll feel a mild-to moderate stimulation feeling, with another moderate sedation feeling. You’ll feel like going out and socializing. Professionals say that while this feeling is enjoyable, taking more doesn’t get you “higher” or make you feel more euphoric, which deters most from taking too much of the substance.


The benefits of Phenibut are numerous, including relaxation, social relief, an expanded feeling of comfort around people where you might have been nervous and more. In many ways, it exhibits many of the most positive benefits about alcohol, even in a healthy, normally functioning mind. It provides creativity, ingenuity, and awareness without giving you the jitters, making you especially tired, or making you feel uncomfortable. In fact, substances like Phenibut provide far more useful benefits than benzos in the long run, like motivation, clarity of thought, and non-toxicity. The negatives proposed by Phenibut withdrawal can be completely avoided with proper medication. Because the liver repairs itself naturally, any damages to the body would be as slight (even better) than drinking. And, those who use Phenibut have a wide variety of benefits to their health associated with taking a new supplement- like an increased appetite, better records and testing abilities, healthier skin, an appetite for companionship, and more happiness and productivity in normal day to day activities. While the negative effects of Phenibut as a recreational drug certainly make the substance sound grim, responsible usages’ benefits greatly outweigh any potential negatives, especially when a routine is finally developed that incorporates a plateau in a responsible fashion, never exceeding gratuitous doses.

Recommended Dosages

Dosages vary widely depending on the product that you receive. Many beginners to the product start with 500 mg doses and slowly build themselves up to higher amounts like 1 g later on in their dosing schedules. Some have even recorded taking more than two grams at a time, suffering from withdrawal later on in treatment. In all cases, those taking the supplement should gradually stop dosing themselves with Phenibut to reduce any possible “hang-over” associated with this relaxant. Capsules are generally better to dose amounts of supplements taken, however purity can be very suspect. Testing should always be done:

  • In a good mood
  • In a bad mood
  • After a full night’s sleep
  • When sleep deprived
  • On a full stomach
  • On an empty stomach

To guarantee that you see the full range of suspected situations that you might face on this substance. Users respond feeling elation with even mild doses, so often playing it safe is better than taking too much and reducing the possibilities of positive experiences with Phenibut later on in your treatment (further tolerance builds much quicker and at rapidly increasing doses). Often, even if negative side effects are gleaned (anxiety or insomnia) these effects can be supplemented with thiamine, inositol, omega-3, valerian root, or melatonin to achieve a calm, sleepy state. The anxiolytic effects of Phenibut would be enhanced and stacked, but only after 2-3 hours of an established Phenibut dosage.

Side Effects

The side effects for Phenibut are mild when taken in the right doses. In fact, when taken in a three days on, two days off time frame, the withdrawal from Phenibut can be more acceptable. Because there are a few number of side effects related to overdose, it’s best to avoid these symptoms all together. In larger doses, it successfully mimics the effects of GHB, benzodiazepines, or alcohol to deliver the positive side effects, but these side effects are similar to other GABA boosters. Phenibut is not to be used in conjunction with other GABA boosting prescriptions because it could cause negative, but mild side-effects, including:

  • nausea
  • headaches, fatigue, and light-headedness
  • stomachache
  • temporary short term memory loss

These effects were found to be temporary, and only occurred when abused and when mixed with different components (like alcohol) or upon withdrawal. Even after suffering intense symptoms, it is highly unlikely that any use will be harmful, especially when used by itself. Phenibut is largely harmless, non-toxic, and not carcinogenic, which means that it leaves the system unscathed when it’s purged through urine or excretion. As with any medicine, there are a wide variety of factors that are specific to various individuals taking the substance:

  • Age
  • Body weight, BMI, and general health
  • Gender (women react very differently than men do to Phenibut. On average, women can take around 10 to 80 percent of their male counterparts.
  • Any medications

Like any other supplement sold over the counter, how your Phenibut reacts to your health is largely based on what the supplement is made of. If calculating these details for yourself at home, start lower than average doses, gradually increasing doses until you know what works for you, provides the slightest negative side effects, and most positive benefits.

Long-Term Effects

One of the most marvelous effects of nootropics is that they are non-toxic and non-hazardous in nature. They’re naturally exuded, and the negative results of the supplements are typically released through endocrine processes. Because Phenibut is far longer lasting than most GABAb agonists, it lasts a bit longer in the system than other substances, although this existence is irrelevant aside from basic withdrawal numerology understanding processes. The effects of withdrawal depend highly on the individual, but never tend to last beyond the seven day-threshold while maintaining sobriety from Phenibut. One of the most positive factors about this particular substance is that it’s non-habit forming (aside from the hangover), completely non-hazardous, and non-toxic. The only negative side effects are associated with Phenibut are related to abusive behaviorism, which would occur with similar usage of any substance, including kidney reactions.

Short-Term Effects

There are a wide variety of short-term effects associated with Phenibut, because these varieties of drugs cause an adrenergic storm that enhances anxiety, melancholia, delirium, suicidal thoughts, a racing pulse, no libido, appetite and a serious lack of energy. These effects, as stated previously are exclusive to large dose withdrawals. Most situations, as used responsibly have no negative tapering off effects when doses remain under two to three grams a day without damaging the liver and causing any negative effects. One of the most redeeming qualities of Phenibut is that it only has a half-life around 5.3 hours in plasma of the blood, which means that Phenibut provides an excellent short-term solution or emergency solution to anyone who needs the relief associated with nullified stress, anxiety, worry, and insomnia.


The effects of Phenibut are multi-faceted and affect everyone differently. The chemicals produced in Phenibut were specifically designed to decrease nervousness, improve sleeping ability, cognitive function, and relieve stress while boosting mood, but many reported feeling as if Phenibut also enhanced focus, euphoria, memory, sight, choline levels and eliminated fear. One of the most powerful reviews is quoted as being amazed that the effects lasted so long- much longer than other nootropics that are more expensive for users over the long run. As a general cognitive enhancer, this neurotransmitter meets the bill, and the mild opiate effects are generally very well received, boosting cognitive abilities and allowing a person to be calm and focused rather than jittery. When many take doses for short periods, they receive only positive benefits, and few repercussions of said supplementation.


Most of the research compiled on Phenibut originates in Russia, stemming from the 1970’s onward. In has built a relatively stunning reputation in overseas markets, peaking in many European countries who use the substance nearly exclusively to treat some forms of anxiety and social angst. Russian scientists and doctors have been further prescribing patients these substances for years, building up “first-aid kits” that contained these essential medicines for space travel, because they’re that essential for adequate and efficient brain and mood health.

Safety Concerns

There are a few acute short-term dangers associated with Phenibut. Because of high anxiety-leveled withdrawals, many using the drug feel like their heart is racing, they’re having difficulty breathing, and that they can’t calm down. These dangers sometimes cause cardiac arrest and other problems associated with panic and anxiety. Aside from these risks, Phenibut is relatively harmless, with some slight gastrointestinal issues associated with stomachaches, nausea, and a feeling of vertigo (or being light-headed) that goes away shortly after digestion begins. The relative dangers are nullified when used responsibly in an environment where the key result is sustained medication of anxiety and other social disorders that stunt social growth.

Liver Toxicity

Phenibut has not been proven toxic to the liver- no more than any other recreational substance. In fact, many blood tests on subjects who have “abused” the substance, taking doses much larger than recommended doses have recorded nil responses regarding possible liver damages in many different tests. Causality between kidney damages and other endocrine damages are unfounded because many of the ingredients are naturally based and harmless in the blood stream.

Is Phenibut Legal?

Phenibut is as legal as going to Wal-Mart and buying a B-12 complex, or multi-vitamin. While it’s more difficult to find than many other substances, it’s not controlled by any laws that regulate the sales, distribution or labeling of this product as a dietary supplement. It’s sold in many different forms- typically as a powder or in a capsule. One dose, between 250 mg and 1000 mg is to be taken daily, starting with lower/moderate doses before graduating to full doses. Because the substance is water soluble and completely legal, powdered forms of this supplement are great mixed into water, juice, or smoothies for ingestion purposes. The powder is slightly bitter however, leading many to ingest the powder with capsules.

Withdrawal From Phenibut

Phenibut withdrawal is often one of the first aspects that anyone hears about this miraculous supplement. While this withdrawal is a definite concern for those who take the supplement, the risks should be weighed in a way that make more sense to readers to understand the true situation that creates a hazard where these substances are concerned. When overused, Phenibut can cause withdrawals, but with proper precaution, err to the wise, and use of these substances in ways that lower the risk of dependence (keeping doses below 2 g) guarantee security when taking Phenibut. Many different substances have Phenibut in them (e.g. Noofen, Phenybut, Fenibut), but it’s all practically the same thing. These chemicals are simply more absorb-able than the ones that the body uses, and they help those with difficulties shaking depression find relief, nearly immediately.

Listed below are several questions commonkly asked about withdrawal from the long – term use of Phenibut:

What Are Common Withdrawal Symptoms Of This?

There are very few actual withdrawal symptoms that are recorded by medical professionals, and most of them would include Irritation and insomnia, while few respondents recorded feeling very anxiety. Another common side effect that accompanied withdrawal was a rapid heart beat that made those suffering from withdrawals more aware of their faculties. Often, in this phase, many feel euphoria as the feelings lift from their brains and they return to normal function, feeling more euphoric for enduring their endeavor. Like any psychoactive substance, there are withdrawal symptoms associated with the drug, but these associations are lessened upon the weakening of your brain’s tolerance of reactive GABA waves. While Phenibut inhibits the function of GABA receptors, when the substance is removed, receptors begin to regain normal function again, and the effects of withdrawal taper off quickly.

How Long Does Withdrawal From Phenibut Last?

Respondents report withdrawals lasting between 5-7 days, depending on the length of use, the amount of use, and the frequency of usage. In every situation (while some where more intense than others) most felt sadness and depression that alleviated itself after the withdrawal lifted and normal function was returned. In cases where withdrawal symptoms are negated, many situations are less severe than with other substances than with Phenibut, making it a great alternative to other types of medicine, even after possible overdose. With the major threat being asphyxiation in conjunction with other medicines, when following a proper regimen, these substances could be deemed non-hazardous, and safe for widespread consumption.

Why Does Phenibut Make Me Tired? Is It GABA?

Phenibut makes you tired because you’re feeling more relaxed, comfortable, and in your element. While you begin to feel tired after taking Phenibut supplement, you’re feeling a delayed and subdued feeling of tiredness washing over your body. GABA relaxes you, but it does not actually put you to sleep (these substances are omega-3, melatonin, etc) instead helping you think clearly, associate thoughts readily, and have better cognitive skills, especially when conversing or when in large crowds. Because Phenibut doesn’t actually affect the receptors directly, it takes a period of time (usually a week) for the body to naturally adjust to the changes that occur when Phenibut is not actively being used in the bloodstream.

How Does Phenibut Affect The Brain’s GABA Receptors?

Phenibut only affects the Brain’s GABA receptors when the synapse is flooded with Phenibut particles that create the feeling of relief that accompanies dosage. After the medicine is not in use, respondents report feeling much more calm, less agitated and upset, however they remained generally lethargic. This is presumably because Phenibut is a stimulant by nature, and therefore exerts muscles, tendons, and neurological functions. In any other facility, the drug is non-toxic and has very minute effects on endocrine functionality.

Can I Use Phenibut As A Sleep-Aid?

As a recreational supplement taken when there are few other alternatives, Phenibut is excellent. Even when used in small doses, it can greatly help to reduce anxiety, especially before bed, which naturally makes you more tired and relaxed. Over time, the effects of Phenibut on your sleep habits are less noticeable, and one of the most poignant effects of withdrawal cause sleep deprivation that can last up to five days. Many users of this supplement report their frustration with these symptoms, but again, most are due to high levels of the substance, abusing it for personal reasons. When used within reason, the substance is virtually harmless, with no proven medical downfalls other than poignant short-term effects related to mass doses.

Can I Take High Doses Of Phenibut?

You should not take high doses of Phenibut, no matter what you think might happen. Scientifically, the brain can only absorb so much of any one chemical on brain receptors at any one time. This means that while Phenibut is non-toxic and non-habit forming, it still can have negative effects on your liver and kidney, as well as creating personal turmoil due to insomnia, sadness, shakiness, or poor appetite. Still, many would suffer the negative effects of this nootropic to receive the myriad positive benefits that this supplement provides.

User Reviews

Many of the individuals that review this substance review it positively. The negative reviews are mostly from those with bad experiences due to poor decision making. All in all, those who have reviewed the drug marvel at how it made them feel, as well as the noted improvements to mental speed and dexterity. Overall, the supplement was suggested for temporary or intermittent use, never intended to be overdosed on, because few (if any) effects occur from such interactions, other than hallucinations due to overdose/withdrawal.

Final Thoughts

Phenibut provides a positive, all-natural solution for those who have issues finding substances that really work for them. All in all, while there are a few negatives associated with this product, most negative benefits are eliminated with smart usages, doses, and management of any hangover symptoms with natural remedies. When users are starting off with small doses, and tapering off gradually, there are no good reasons why they shouldn’t experience the mood-lifting effects of one of the oldest, most established nootropics on the market with one of the best reputations out there- strong, poignant, and perfect for the establishment of a well-rounded mind. Proven to increase brain function, make you more vocal, and help you cast away social anxiety, Phenibut is something that practically anyone would want to get their hands on.
