Has anyone got any legitimate answers to the toxicity and use of this GABBA drug inquiring minds would like to know. Is it safe to use on a limited basis or is this substance a big no no. I have tried this drug and quite like it its great for anxiety although takes two hours to have an affect. Every time I have taken it I wake up with pains in my kidney region although this does not last for too long once I am out of bed and had a shower the pains dissipate. I do believe I had withdrawal symptoms from it once after a 4 day binge but they were not too bad shivering feeling very cold and clenching my jaw, But these W/Ds seemed to pass after a really hot bath I did think I was coming down with flu but nothing came of it and I put it down to the Phenibut. I am not a big drug user and this was the first W/D symptoms I have ever encountered can someone give me some legitimate answers to this drug which is sold on body building sites
