F-Phenibut FAA, Powder

F-Phenibut FAA (4-Fluorophenibut free amino acid) is a several-fold more potent derivative of the nootropic and anxiolytic GABA derivative, Phenibut.

F-Phenibut FAA is the free amino acid form of Phenibut, It is close to neutral pH. It has a mildly bitter taste and is moderately soluble in water.  It is highly pure: more than 99.5% Phenibut molecules by weight (actually, no impurities at all are detectable by HPLC).

Phenibut FAA is a fine white powder and is, therefore, less dense than the crystalline HCl form (an equal mass of Phenibut F.A.A. occupies approximately twice as much volume as Phenibut HCL crystals).

Phenibut is known to have a wider spectrum of effects than baclofen; for example Phenibut has been found to be more effective as a nootropic and neuroprotective compound than baclofen, while baclofen has a more narrowly focused spectrum of effects and anecdotally shows a reduced tendency to induce habituation or tolerance to its effects upon chronic daily administration.
