i had a guy i worked w/ telling me how it got him in shape and built him up a bit w/out any exercise. he was/still is a big cluber/drugee. anyway i checked into it and there is a short article about it in bill phillips book also(third ed.)
the way you started to "like it too much" is common. for most it brings an almost drunken feeling and a calm pleasant mood like pot.
the big downside is the potency and inability to tell just whats in it. if you can get good stuff from the same source, you MIGHT be ok. but picking it up at a club is very dangerous. really potent stuff directly caused over 10 teenaged deaths here in fla last year. i forget most of the facts
but case in point, ya never know what ur getting.
