Nootropics Phenibut Powder 4-Amino-3-Phenylbutyric Acid HCl CAS 1078-21-3

Also known as "4-Amino-3-Phenylbutyric Acid," Phenibut is a non-prescription pharmaceutical that is actually a GABA molecule with the addition of a phenyl group. Russian researchers discovered that by changing GABA into 4-Amino-3-Phenylbutyric Acid, it was able to cross more easily into the nervous system and across the blood-brain barrier. Since it is a GABA, an inhibitory neurotransmitter, derivative, it increases GABA levels.

Phenibut is a white crystalline powder with a very sour taste. It is readily soluble in water, soluble in alcohol, and the pH of a 2.5% water solution is between about 2.3 and 2.7.

• Phenibut is used by bodybuilders to reduce fatigue and improve neurological functions.
• Phenibut has been and is still used medically to treat stress, relieve tension, improve sleep, and as a potentiate for other medications.
• Phenibut is a derivative of the naturally occurring inhibitory neurotransmitter GABA.
