Does anyone have recommendations where to buy best Phenibut?

[turquoise53]

I was given a possible anti-anxiety remedy called "phenibut" by one of our members. I've gone online and there are several places advertising, however, it is difficult to distinguish which is the best one. I've watched videos on this, still, I'd like to know if anyone from our community has tried a specific one. I am still having anxiety, and I also take Ambien for insomnia and my doctor has forgotten to call in a Rx. I have had to remind the office I need this med. Frustrating!!!!
