Youre probably long done rolling by now, and the question has already been answered, but yeah...
When I pressed/capped my own pills, I made them .1 each.
Snorted, it took me 2 or 3 pills for a desirable roll, but than again im big. So no hurt in starting small and working up. Id say snort like 75mg, then parachute another 100, and wait for an hour, and redose if necessary.
Hopefully you brought water though... it sucks trying to buy drinks at fests/raves wen they gouge you completely. Have fun paying $12 for water, ma nigga.
Let us know how its going
