Phenibut is chemically known as β-phenyl-gamma-aminobutyric acid. It is available as a nutritional supplement, over-the-counter drug or sometimes as prescribed medication in many countries and sold under the brand names AnvifenFenibut, and Noofen  and others.

Phenibut HCL is intended to relieve anxiety. It is known for its ability to reduce stress, anxiety and improve sleep without causing drowsiness. In Russia, where the drug was originally invented and produced, it is used as prescribed medication for treatment of large variety of  psychological conditions including treatment of asthenia, depression, alcoholism, alcohol withdrawal syndrome, post-traumatic stress disorder, stuttering, tics, vestibular disorders, Meniere’s disease, dizziness, for the prevention of motion sickness, and for the prevention of anxiety before or after surgical procedures or painful diagnostic tests.

Some reports suggests that Phenibut may have revitalizing and rejuvenating effects on the body, possibly by increasing growth hormone levels, and it seems to improve skin and muscle tone, as well as general health and overall well-being as a result of reduced stress and improved sleeping pattern.

Although in USA Phenibut powder  is not approved by FDA to treat any medical condition it is sold and marketed as supplement and sold as phenibut powder or capsules. Both available from us.

Benefits of Phenibut

Phenibut is primarily used to treat anxiety and stress. Aside from this, there are a lot more other uses for this nootropic drug, which includes:

  • Alcoholism
  • Fear and anxiety
  • Stress and fatigue
  • Depression and insomnia
  • Improving memory, learning, and thinking

The effects of phenibut HCL simultaneously combine mild-to-moderate sedation with mild-to-moderate stimulation, allowing one to feel physically relaxed and mentally focused at the same time.  This increases sociability, lowering stress and inhibition levels without impairing judgement.

It is recommended however to use Phenibut HCL cyclically with days on and days of to avoid developing tolerance.

As a nootropic, phenibut enhances the brain’s cognitive function. As emphasized by Lapin, in an article published in the journal CNS Drug Reviews, this drug promotes desirable improvements in learning and memory capacities, enhanced attention and improved mood. This effect is believed to come from the simultaneous action on the cellular receptors for GABA-A, GABA-B and dopamine.

Several studies provide evidences for the neuroprotective capabilities of phenibut. This drug plays a very important role in protecting the neurons in the brain, especially during times of stress. It also has a very important role in protecting the neurons in times of oxygen deprivation, such as in injuries or impairment in venous flow. Phenibut HCL also protects the brain neurons when the body is engaged in extreme physical exertion that can cause overheating and decreased capacity for work.
