It certainly won't mimic GH, according to studies. But like Par said, it converts straight to GHB. The taste is unbearable, but you wouldn't be consuming high amounts. Email me the site you found it at and I'll check it out.
You definitely CANNOT synthesize GHB from 1,4-B, or not in a productive manner anyway. Sure, it is easy to convert a -CH2OH group in a -COOH (refluxing for a couple of hrs with acid bichromate should do), but the problem is that butanediol has TWO -CH2OH's, and oxidizing both of them would result in worthless succinic acid (a normal component of our body, but without psychoactive effects). In the body the "synthesis" of GHB from 1,4-B doe work, but only because enzymatc reactions tend to be very selective. Therefore, it's better to let your body do the work and just swallow the BD as such. As is the case with GBL, there is no need to go trough the effort and losses of syntesizing GHB from it, cause the thing it does in your body is exactly the same.
Sodium based G is the best. And noone goes through the trouble to make that kind anymore. Sodium based G makes you feel like a MILLION bucks when you wake up from it. The floor stipper shit thats out now will fuck you up but it won't help you sleep any.
