Well The Mass mosters like Ruhl, Cutler and Ronnie I would say would need about 1000 to 1500mg of test along to maintain that muscle, Then the rest would be to make the gains. Cutler was 5'9 290 pounds. I Bet his off season bulking cycle to go from 260 to 290 had a ton's of MG's, I Suppose smaller guys like Dexter would not need as much juice to maintain size as well as making gains. BDTR is 6' 300 at 10% and needed 2 grams of test and 1 gram of tren now if cutler is 5'9 290 at 3% and no water, Go figure the cycle. I would bet his new and bigger chin would make Jay Leno proud so He most take a sh*t load of HGH.
