I have never tried powder stuff, but
Had Charge pills over 10 times so far... Had 5 pills each time. They're good fun but I found the comedown to be pretty bad.
I also had other brands: the good stuff, bliss, jet, jump... All pretty similar. Minor hallucinations at higher doses... Often feel real smacked out i.e. can't feel the floor, lost sense of direction, sense of time...
BZP is alright and i still do it as long as i have some weed on me for the terrible terrible comedown.
And of course, would much rather prefer E, but i dont wanna abuse that wonderful drug... So, e every couple of months, bzp every 2 weeks or so...
