depending on milligrams, im a chic and for my 15's i only took a half of one and i was fuked up, i think if you took over 2 at one time would be very dangerous and risky, dont become a junky man cause thats what they do and for god sakes dont snort the shyt! i have no respect for fukers that snort pills just because they are inpatient to feel the fukn high....dude just take the pills as the dr said to, which means nothing more than one at a time and you should be fine.....
