Definately just start with the basics. The best value when it comes to creatine is to buy it in bulk...you can manage to buy 500 servings for around $20. Check out CNW, Bulk Nutrition, Primaforce,etc. as they all have bulk containers of both CEE and Creatine Mono. Other than that you should pick up a multi-vitamin, protein powder, fish oils, and possibly a stim to take pre-workout. Drink as much water as possible, eat, and grow!
