Synthesized by professor V. Perekalin in 1959, Phenibut was quickly recognized as a very promising chemical compound, as it had both psychostimulating and anxiety-reducing effects. After several years of research, Phenibut was added to the Russian astronauts’ medical kit: it could decrease the stress of cosmonauts and also allow them to maintain the same performance level, unlike usual tranquilizers. It is a known fact that the cosmonauts of the Soyuz-Apollo Test Project had it in their medical kits.

Phenibut is a derivative of the naturally occurring inhibitory neurotransmitter GABA, which can cross the blood-brain barrier much better than the original compound. Years of extensive research on humans revealed that Phenibut can be beneficial if you have the following symptoms:

  • Emotionally labile disorders;
  • Asthenic disorders (lack of energy);
  • ADHD in children;
  • Alcohol withdrawal;
  • Poor sleep quality in older patients;
  • Lack of motivation;
  • Other conditions, characterized by reduced intellectual productivity.


Phenibut is also used by athletes and bodybuilders, as it increases resting and post-exercise growth hormone secretion.

Special things about Phenibut:

  • Instant anxiolytic effect.
  • Phenibut improves attention, memory, speed, and accuracy, unlike tranquilizers.
  • Improves motivation but might drain your willpower.
  • Small dosages have calming and nootropic effects, while larger ones have a stimulating effect.


Note: Phenibut is a completely safe medication when used in moderation. However, if taken in large quantities for recreational purposes, it is likely to cause tolerance and withdrawal symptoms. It has different effects when taken in high doses. Therefore, we limit the maximum order quantity to 4 packs of 20 pills.
