I think you need to get used to going in the gym, weight training, and eating right to support it naturally awhile before you jump on the AS bandwagon. By gaining muscle so quickly it won't give your tendons/joints time to strengthen as well, resulting in injury-a setback that could fuck you up worse than anything. It sounds to me like your lifestyle isn't conducive for serious bodybuilding anytime soon cuz your schedule is so demanding. This isn't something that you can "half ass" your way through. If you approached school with the same attitude you'd be saying "I wanna finish med school but I'm only gonna study just enough to keep from failing" With that attitude I highly doubt you'll be graduating/interning/ establishing your own practice to pay back that monster student loan anytime soon.
Anyway, it's your body to do with as you please. If you're gonna do it, I recommend a test only cycle of 200mgs-500mgs a week tops for 8-10 wks. Everybody's body responds differently to different drugs, so by using one drug instead of 3 you'll know exactly what gave you(or didn't give you) the results that you want. You also won't be wasting $$$ by using more AS than your body can handle so soon in the game.
Keep in mind that going to the gym and using AS is the easy part. Your lifestyle outside of the gym is truly what will make the difference in the appearance of your physique. Personally I feel that you have too much on your plate w/ med school to even consider trying to obtain the physique that you require-with or without AS. It seems like you want to use AS as a crutch to get you through a somewhat half assed training regimen as opposed to enhancing a flawless one. I've been training people on and off for 17 yrs, and I have yet to see a Dr or Lawyer balance their career, training, and social life successfully. So I can only imagine it's going to be an even bigger miracle for you reach your fitness goals. You really need to think out your career path well before you sign on for something like med school. Every Dr I've met is as tired on a day to day basis as a single mom with 2 kids and a full time waitressing job. My clients that are Drs show up to the gym on very little sleep in a zombie like state. Chances are that from a health perspective they'd be better off getting more sleep and doing full body routines on the soloflex at home 20 mins EOD. Sure, they may roll up to the gym in a phat S500 Benz, but they shouldn't expect to have this killer physique since the majority of their time is invested in earning $$$. It's no different than being a personal trainer that works 25 hrs a week tops that's living above his means and trying to make a $1600/month Benz payment-unless you're one of those Hollywood trainers of the stars, or you're independently wealthy to begin with, it probably aint happening unless you work twice as much(causing your own training to suffer). Anyway, sorry if I sound a bit harsh-but since fitness has been a part of my life since I was a kid, I knew from about age 21 on that having a career outside of the fitness industry wasn't going to be for me. Sure, being a Dr and serving mankind is a nobel thing to do-but in no way is it conducive to living the bodybuilding lifestyle-at least if you want a social life and getting laid once in awhile.
