I am 5 11, 150 lbs, and consequentially 5% body fat. However, it appears as though I am an ectomorph, because I have had a six pack since I was 10, but my aunts, uncles, cousins, etc... typically remark that I am sooooo skinny. Yeah, but I also eat 3800 calories per day, and I sometimes barely reach that amount without extreme nauseau. Short of Testosterone- although I have a hookup for androgel-, HGH, anabolic steroids and estrogen reducers, what supplements can I take to help gain mass? I am currently on whey and casein protein, BCAAs, l phenylalynine, l arginine, taurine, ZMA, multivitamins, colon probiotics and creatine (4-7 g).

i HAVE been considering taking a carbo-loader supplement with an 800 calorie serving size, 50g carbs, 15g protein, 10g fat made by multiple companies, but that seems foolish.

edit: also, would 5x5s or 4x12s be better for my goals? I run 3 miles in under 19 min 2x/wk...should I cut the cardio from my routiine until I have hit at least 170?
