Phenibut FAA (Free Amino Acid) has close to neutral pH, making it very suitable for sublingual administration. It has a mildly bitter taste, and is moderately soluble in water. It is highly pure: more than 99.5% Phenibut molecules by weight.

When consumed in the usual way, Phenibut FAA is about 15% more efficient than Phenibut HCl, however  when consumed sublingually, Phenibut FAA is as much as 3 fold more efficient by weight (only 1/3rd as much is needed to achieve the effect). Also, the sublingual route allows Phenibut FAA to be absorbed more rapidly, allowing the benefits to take effect a lot faster.
