Okay, Now I really feel like an idiot. After taking a closer look at the label on my GBL I've found that it not only contains GBL but N-Methyl -2-pyrrolidone as well. I guess this explains a lot of the trouble I've been having with converting to GHB. Can anyone help me? Can the N-Methyl... be removed or should I find a new GBL source. I would really appreciate any help.
Thanks,
Sally
