i just recently got prescribe ADDeral about a 3 months ago and i love it.....hahaha......i did notice that it literally kills your appitite but ive been pushing through it....but other than that...my workouts were very intense before i got on cycle too...no that im on its scary for the people in the gym...haha....but other than the appitite and crazy workouts...i havent had any problems....other than i feel like a crackhead the first 30 mins once it hits but thats a good euphoric feeling...its just great
