Who better to prey upon than the desperate?
All these ingredients can be purchased for a fraction of the cost at a local quality supplement specialist.
GABA, for one does not even cross the blood brain barrier, and so is not effective in any way, in its raw form. All plain GABA supplements are almost completely useless, until such huge amounts are stored in tissue that they eventually leach into the spinal fluid.
Phenibut is intended as a means of by passing that, by combining GABA with niacin, but isn't a great route. A similar strategy is Picamilon (using a better, more complete molecular bonding route between GABA and a B-vitamin variant more fitted both to transmission and complete molecular conversion)
L-Theanine is the calming amino acid found in green tea, and while a great approach for long term, gradual reduction in peak anxiety levels over time, is not at all pronounced enough to give any immediate relief, especially to those whose symptoms reach the threshold of panic, or other somatic (physiological) manifestations (increased heart rate, etc.).
Taurine is included in most energy drinks, another amino acid associated vaguely with a "sense of well-being" but which has never been identified as active in any research, to date (not that that means anything, exactly, but still).
To get the amounts of these, combined, which you'd find in this product, you'd probably spend all of about $30--that's retail, buying one bottle each only.
So if you want to pay the additional for their trouble of combining, packaging,etc--go ahead. Just don't get your hopes up.
For someone with any degree of clinically diagnosed Social Anxiety, the effect might be to take only the finest cutting edge off. Nothing more. And not immediate, as in take one dose and feel an effect in 30 minutes.
The Phenibut alone would be doing all the work, really, and there are better choices than that. Picamilon, as mentioned, is similar but much better. It can be found online. Biogenesis antiaging is one source, but they're almost always out (I'm not a rep). They're reputable

Take lots of B-vitamins (Panthotenic acid, especially), exercise, and try cortisol reduction supplements like relora (main ingredient being magnolol/honokiol--not easy to find elsewhere although becoming better known now).
Relora's actually likely to be a lot better than this product, and is available at just about any supplement carrier, now.
