Interesting ! Some of these ingrediants sound a lot like methylphenyltetrapyradine--otherwise know as MPTP ! Ever hear of the "Case of the Frozen Addicts" ?? MPTP metabolizes into MPP+ and destroys the substantia nigra--turned out to be a breakthrough for research by allowing true Parkinson's to be given to primates other than man. Left the young would-be drug users permanent Parkinsonians for life however, except for a couple who got fetal tissue transplants Sweden and are gradually recovering.
