I finally got to 220 @ 5'11'' (6% mind you, I am no fluffy 220) by eating a HUGE breakfast every morning, and then upping my carbs throughout the rest of the day dramatically.
My breakfast is a cup of oats, 4 whole eggs and 8 egg whites (I drink the eggs raw in a cup. I can't eat cooked eggs, it takes too long).
Then I have a second cup of oats (cooked of course) in the evening. Also, after I train I use 3 scoops of that 2:1:1 recover stuff (105 grams protein, 105 grams carbs). One hour later, I have a 2:1:1 recover shake with 2 scoops of the stuff (70 grams protein, 70 grams carbs).
Then I kept my diet as it was- I consume three other whole food meals throughout the day, usually 2 of them being rice and beef, and the other being whatever I want short of something I wouldn't feed my sister's cat such as mcdonalds. I just essentially added 200 grams of carbs from the shakes, and an additional load of carbs from the oats (I don't know the figure). This shot me up from 212-220 relatively quickly, and since I just started pharm grade growth regimen @ 5 iu, my bf% actually has been dropping as my weight has been going up.
I am also on 500 mg deca, 750 sust, and 100 mg injectable d-bol daily (d-bol is about to end, i only run that stuff for 5-6 weeks at a time).
Just my 2 cents. I don't think you need to up the gear per se. If you can't grow on 1250mg-2000mg of AAS, then your diet is truly the problem (I think 1250 mg-2000 mg is the perfect amount in conjunction with a small dose of pharm grade or equivalent (kigs, novo, etc') gh @ 4-8 iu per day.
