Not yet, but one day. I am a fiarly big guy, not a models phydique or anything, but I won't be happy until I get another 15-20lbs of lbm. I' standing at 5"8 now with 12% and 231lbs. I will be getting down to 8% and then I will try to put on the muscle without the fat gain. I'd like to be under 10%bf with 235lbs of muscle. If I get to there I will do a comp. it's just I have alway's been too nervous
