Phenibut Free Amino Acid – Powder, 50 grams

Phenibut Free Amino Acid (FAA) is the free base form of β-phenyl-γ-aminobutyric acid, distinct from Phenibut HCL in that it lacks the hydrochloride salt component. The free base form has lower molecular weight, different solubility characteristics, and is used in research applications requiring non-salt formulations. It retains the same GABA-B receptor agonist and GABA-A ρ modulator pharmacological profile as the HCL form.
