Quick background on my lifting career, I am 16 and I have been going at it for about 18 months and have gained 45 pounds with little to no fat gain. I am currently 5'7'' 160lbs. I was progressing steadily up until about 4 months ago when everything just sort of halted in terms of strength progression. My bench/military/DL haven't gone up in months, in fact my bench has gone down by about 10-15 pounds. I know plateaus are normal, but one of this length doesn't seem right being the beginner that I am. I also am aware that it is definitely due to something I am doing wrong, the most likely thing being I am not taking in enough food. Just so everyone knows I am not some idiot who trains arms and benches 5 times a week and then wonders why he isn't gaining, I have done my research and follow fairly reputable programs that include all the big lifts. I am currently on Madcows 5x5 intermediate 3rd week.
So my question is, how much would GOMAD help me at the moment? It seems that this option would be one of the easiest ways to increase my cal intake enough to get me out of this damn rut I'm in. What has your experience been with GOMAD and its impact on strength progression? I know its recommended mainly for people who are very new beginners but how effective would it be for someone at my level when combined with Madcows 5x5 would you guys think? Here are some stats just so you know where I'm at in terms of strength, Bench 185x5(used to be slightly higher), Squat 285x5, DL 335x5, Military 125x5.
