experienced meathead here..
your focus now, esp. considering we're getting into fall, needs to be a clean bulk. this means eating above maintenance calories from quality food sources while lifting heavy with a proportionally small amount of cardio (elliptical trainer, stationary bike, etc) on the side. go to
http://forum.bodybuilding.com for more help on workout routines, etc. t-mag is a complete joke. focus on cutting in early spring once you have some muscle mass.
and whoever suggested 5x5, that is not at all suitable for his goals. he doesn't want to be a fatty powerlifter. shoot for 9-10 reps per set to gain visible muscle mass and a nice shape, which is what you're looking for.
to the person who said hgh is "too expensive" that is ignorant blather. it is not too expensive, is available only in injectable form, and is quite effective, particularly for bodyfat loss. however, i would never touch it, nor would i touch even the lighter anabolics (anavar, winstrol, primo, etc) without solid workout consistency for at least a few YEARS. and even then I personally wouldn't touch those substances.
if you're brother's doing this, good for him, but you should not. bodybuilding is a lifestyle, not something you just do for a few months and expect immediate results. make sure he has some clomid and or nolva on hand to get his balls back post-cycle. good luck with your workouts man
