For those that are thinking about trying this....do a search. There are many people who have had problems with it. I used it for a while...it fucked up my liver pretty bad. It was the only thing I was taking, and I had yet to ever cycle. A major part of its metabolic pathway uses alcohol hydrogenase as an enzyme for conversion....we are talking liver stress. My recommendation, if you must, use real GHB, or 99.99% GBL IN MODERATION!, or don't use any at all. Both can and will cause dependence if abused.
