Phenibut XT is fundamentally a GABAergic supplement, known to bind to GABA B receptors in the brain in much the same way as the GABA neurotransmitter.
Phenibut was initially developed in the 1960’s in Russia as a way to increase activity of GABA. This neurotransmitter is known to have an inhibitory effect on neurons.
While GABA is still to this day sold as a supplement for relaxation and as a sleep aid, neuroscientists have known for some time that this compound is incapable of being transported across the blood-brain barrier to any great degree.
Phenibut’s molecular structure is nearly identical to GABA, but a phenyl ring has been added on. The addition of the phenyl ring is what allows Phenibut to transport across the blood-brain barrier. This means that unlike GABA which must be made in the brain to cause an effect there, Phenibut can enter into the Central Nervous system from the circulating blood stream.
SNS Phenibut XT has been used for anxiety because this disorder is characterized by over-stimulation of your neurons. Individuals with Anxiety Disorder feel like they are unable to relax or shut their mind off.
Some examples of types of anxiety include panic disorder, phobias such as social phobias, post-traumatic stress disorder, obsessive compulsive disorder as well as general anxiety. It can cause you to fixate on certain problems and experience inordinate amounts of fear, apprehension and worry even to far-off possibilities.
This is sometimes characterized by the persistent flashing of images in your mind or being unable to control repetitive thoughts in your mind. Frequently, anxiety is associated with low levels of GABA or an improper balance in neurological activity.
- Powerful anxiolytic for stress reduction
- Improves sleep and may reduce insomnia
- Neuroprotective and cardioprotective effects
As a means for increasing GABA stimulation in your brain, SNS Phenibut can prevent or inhibit the over-excitement of your neurons that forms the underlying basis for anxiety.
GABA is an inhibitory brain chemical that is released when neurons are firing too fast. It essentially puts your neurons back into balance so that they have more adequate responses to external stimuli. Users who take Phenibut XT say that they feel more calm and do not become overwhelmed or stressed out as easily.
Below are the benefits that Serious Nutrition Solutions says can occur from using Phenibut XT:
- Relief from Anxiety
- Better Control of Stress Levels
- Increased Social Behavior
- Mood Brightening and Feelings of Well Being
- Improved Sleep Quality & Insomnia Relief
- Sense of Relaxation
- Heightened Concentration
- Enhanced Brain Power
Most of the scientific research on Phenibut is somewhat dated, as the majority of studies were done in Russia when the compound was developed in the 1960s. More current research needs to be done to fully understand the benefits Phenibut can have. While Phenibut is used as a prescription medication for anxiety in Russia, in the USA, the FDA has not approved Phenibut as a drug for the prevention or treatment of any conditions.
Should you use SNS Phenibut XT?
The next question is, should you buy your Phenibut from SNS or are there other source available that are better?
Serious Nutrition Solutions has a good reputation among supplement users and they have a wide range of products in their line. While they are not as well known for nootropics and other cerebroactive compounds, they are very popular among bodybuilders and in other athletic performance enhancement circles.
You can buy 500 mg SNS Phenibut XT 90 capsules for $32.95. Other ingredients include gelatin, magnesium stearate, silica, and rice powder which are necessary for the encapsulation processes. This means that their Phenibut is not entirely pure.
Depending on how frequently you use it and the dosage you use, one bottle could last up to three months or more.
There are two main cons to consider when deciding whether to buy SNS Phenibut XT or going with another brand. Firstly, it can take this product 2 – 4 hours to kick in which is longer than what you would expect when using a bulk Phenibut powder product. This is of course something that you can adjust for by planning ahead when you will need it.
Another consideration is that this supplement tends to cost more on a per dosage basis than if you were to buy unbranded Phenibut from an online nootropics vendor. Depending on how much you purchase at a time, there can be substantial savings when buying the generic raw ingredient as opposed to purchasing SNS’s product.
It is largely a matter of personal preference which formulation you decide to use, but these would be two important factors to weigh.
- Most effective supplements to improve mood
- Optimize levels of dopamine, serotonin and GABA
- Protect against stress and anxiety
How to Safely Use Phenibut
It is important to follow manufacturer product labeling usage directions for Phenibut XT closely in order to avoid negative side effects as well as developing a tolerance or withdrawal symptoms. In large amounts, Phenibut can be dangerous and cause serious side effects.
Before beginning any new supplements it is recommended that you speak with your doctor. Proper dosages depend on many different factors, including your age, physiology, and reason for taking the supplement. Your doctor will be able to determine the best Phenibut dosage for your needs, as well as determine if the supplement may negatively interact with any other supplements or medications you currently take.
According to SNS, the best way to use this supplement is to take 1 to 2 capsules either once or twice a day. For more intense anxiety symptoms, sometimes 3 or 4 capsules are taken at a time. Do not take more than 4 capsules (2,000 mg total) in any 24 hour period. SNS also cautions that you should start with a smaller dosage to find out how it will work on your personal biochemistry.
Most users start to feel the effects of Phenibut XT within 2 hours of taking it, however some users have reported it taking much longer, while others feel the effects sooner. The half-life of this compound is approximately five hours, hence it’s best to space out your dosages so that you do not have too much in your system at any one time. It is also important not to take for more than 5 days without a 2 day break. We would recommend an even longer break – i.e. 5 days on and at least 5 days off.
There is a chance you can develop a tolerance to Phenibut XT if you use it consistently for long periods of time. This can be accompanied by withdrawal if you are not careful about cycling your doses and giving your body a chance to rest and reset.
Taking too much Phenibut at once can also cause serious overdose symptoms similar to if you were to drink alcohol in excess, as alcohol and Phenibut both activate similar GABA receptors in the brain. It is suggested that the lowest dosage is used to start so that tolerance can be assessed and overuse can be avoided. Another strategy is to take this nootropic for not more than a duration of one or two weeks at a time to keep tolerance low.
You may find that SNS Phenibut XT works best for you when you use it sparingly and only as needed for improving relaxation and decreasing anxious thoughts.

How can you justify saying that there will be a difference in onset between this product and generic? It makes no sense at all. Even if the product isn’t pure, there will be little difference.
Can you explain further
Hello Xcel, thanks for the question.
There will be a difference in absorption time from taking Phenibut powder versus an encapsulated product. When the capsules are consumed, the capsule must first be broken down in the stomach in order for the active ingredient to be released. Dissolution times will differ depending on ingredients used to make the capsule as well as stomach conditions.
