No but I have been thinking about it, I dont have any or know where to get any in my area. I just eat alot and lift alot, I have put on 20lbs. in 2 months of just trying hard to do everything right. I follow chad waterburrys get big program. I feel like my gains will really come once Im done with school because as of right now I only lift 3x a week and I sleep 4.5 to 5 hours a night for the past year and a half since I am a full time worker and full time student....work at night 8 hours...go to school all day 7 hours....then lift on lunch break.
