i had ordered some online once.. i don't remember what x's it was, and i ordered a few amounts of it..
the stuff was nasty, i can't take the taste, it was wretched to say the least.. i put it in a brand new pipe i had, and i refuse to smoke out of it now, lol..
anyhoo's, i put a nice amount in a bowl, and smoked some.. taste was worse then the smell.. but i guess the stuff i got was bunk as i really didn't feel any of the effects that i have read about on here and other sites like erowid, basicly i wasted what ever money i spent on it..
i even gave some to a dude at work and he had she same results, nada..
after that experience with it and that nasty taste, i really have no desire to try it again really...
check out erowid for dosage amounts, effects and shit like that..
