What is Phenibut?

Phenibut (beta-phenyl-gamma-aminobutyric acid) was discovered in Russia during the 1960’s. It is a derivative of the neurotransmitter GABA and is capable of passing the blood brain barrier.

Phenibut is regarded as a nootropic for its ability to have an effect on various neurological functions. It is a gamma receptor agonist and also causes the release of GABA.

Phenibut XT Dosage Notes:

Phenibut’s effects can be dosage dependent, with the typical effects of Phenibut being felt in 1.5 to 2 hours although some people notice effects sooner.

Suggested usage ranges from 500 to 2,000 mg. divided over 1 to 3 daily dosages. The half-life of the compound is approximately 5 hours so many individuals space their dosages out throughout the day except for those using it solely for restful sleep purposes.

Tolerance can develop to some of the effects of Phenibut, although many people report that it does not develop to the nootropic effect.

To prevent tolerance from occurring, many people take Phenibut for periods of no more than 2 weeks followed by an equal off time. Alternatively, some individuals use it for a 4 day on, 3 day off or 5 day on, 2 day off type pattern.  Others may not use Phenibut daily or a certain pattern and choose to only use Phenibut as needed.

The effects of Phenibut can vary from person to person so it is suggested that people start off with a smaller dosage and work their way up in order to find the dosage that works best for them. 

Some General Dosage Observations:

As a Short Term Sleep Aid – The typical dosage for short term sleep support is 500 to 1000 mg. approximately 90 minutes to 2 hours before bedtime. Since Phenibut is reported to produce longer, deeper sleep, it is suggested that when taken for this purpose that Phenibut should be taken when there is time for a full 8 hours of sleep until individual response is assessed.

Mild Anxiety Support The typical dosage for mild anxiety support is 500 mg. 2 to 3 times per day in between meals for periods of up to two weeks, followed by a week to two week break.

For Acute Bouts of Anxiety – The typical dosage for acute bouts of anxiety is 500 to 1000 mg. 2 to 3 times per day. Note that we cannot recommend exceeding 2,000 mg. per day. When used for this purpose, Phenibut is generally used for periods of several days followed by a week to ten day break.

Other Nootropic Properties – The typical dosage range for nootropic effects are 500 to 1500 mg. per day for 2 to 4 weeks followed by a 2 week break.

Note about Phenibut & Alcohol: Even though many people products containing Phenibut along with alcohol to intensify the effects of alcohol, we cannot condone this action and do not recommend Phenibut be used for this purpose.

Stacking & Versatility:

Phenibut XT can be stacked with SNS Focus XT, Noopept XT, Huperzine A 99%, or a variety of other SNS products for improved, synergistic results.*
