xtacy and crystal meth does that not this...xtac and crystal, raise dopamine almost a 1000 percent higher then ghb, which is a cause of what your talking about....crystal meth raises your dopamine higher then anything else on planet earth, and after years of continued usage, people can still recover from it, ALTHOUGH, very rarely do they heal 100 percent, even cigarrettes take years to recover from, and i highly doubt your body could recover and produce normal levels of test after steroid use as well...every drug takes time to recover back to normal from, but permenant wholes in your brain, no....produce the study that shows that please...i know that i can produce at least 15 studies showing the positive results....besides this drug would have never been made available for prescriptions, if it was burning peoples brains lol....add to that, that in many countries it is legal....people RARELY die from straight up ghb, the people that die from it, are combining it with alcohol, weed, vicodins, heroin, amphetamines, etc etc etc etc.....did you know that your body has ghb in it naturally? and that when you add more, its elevating whats ALREADY in the body?
