I believe you are taking a wrong route from the begining. Having two weeks experience means you need to focus on very basics, that is :
1/ lift smart and hard - check Chad Waterbury's Big Boy Basics routine or ABBH, stick to compound lifts, lift heavy
2/ eat well - read John Berardi articles on this or his site, or get yourself his Scrawny to Brawny ebook or Precision Nutrition
3/ do not rely on supplements except pre/post workout drink and protein powder (however try to get as much as possible of protein from food instead of taking 2-3 shakes per day)
I have started to move weights at the age of 37 and I have lost two years for nothing due to following bodybuilding magazines workouts, being afraid to eat enough in order to not to add any fat and believing that supplements will miraculously add muscles to my frame.
As soon as I went to the basics, at the age of 40, I started to see progress - going from 160 to nearly 190 lbs with lower body fat than I have started with. Moreover, I now squat, deadlift and bench press 3-4 times more at 42 than I was able to at 40. Well, I still call myself a beginner but I see a constant progress and I hope to reach my goals sooner or later and then setting a new, more ambitious ones.
The key is consistency, dedication and avoiding bullshit. Lift hard, eat and rest well and you will surely succeed!
