99% Purity 4-Amino-3-Phenylbutanoic Acid Phenibut Faa Powder Safe Clearance CAS 1078-21-3 USA Europe Spain

Phenibut is a synthetic compound structurally similar to the neurotransmitter gamma-aminobutyric acid (GABA). Originally developed in Russia in the 1960s, it is valued for its anxiolytic (anti-anxiety), sedative, and calming effects.

Phenibut primarily works by binding to GABA receptors in the brain. As a GABA-B receptor agonist, it enhances GABAergic neurotransmission, reducing neuronal excitability and promoting relaxation.

• Anxiolytic Effects: Reduces anxiety and stress, helping alleviate symptoms of generalized anxiety disorder, social anxiety, and situational anxiety. Users report increased calmness and reduced anxiety.
• Sedative Properties: Promotes relaxation, improves sleep quality, and reduces insomnia. Effective as a sleep aid for falling and staying asleep longer.
• Nootropic Potential: Some users report cognitive enhancements including improved focus, attention, and mental clarity, though scientific evidence remains limited.
