Phenibut was first synthesized by the Russians during the 1960s to relieve tension, anxiety and fear, according to one 2001 study. (It is still prescribed there for these purposes today.) Phenibut is a nootropic or smart drug, a supplement that purports to enhance cognitive performance by increasing memory and attention.
Most commercial phenibut is in the form of the hydrochloride salt (HCL). In this form, the gamma-Aminobutyric acid phenibut is reacted with hydrochloric acid to form a stable, easily dissolvable, acidic, crystalline salt. Alternatively, phenibut can exist as a Free Amino Acid (FAA). In this form, phenibut is close to pH neutral, non-crystalline, slow to dissolve and mildly bitter.
