Mike, you need to become less focused on supplements IMO. This is a newbie mistake, and many veterans of lifting still relies too much on various supplements, such as protein powders and such.
I recommend you buy a real book on sports nutrition, which will help you build a knowledge foundation, and also decrease the dependancy which you would have if you had less knowledge.
You need to eat mainly carbs. But to do this, you need to really learn what kind of carbs are good for you, and WHEN you should eat those carbs. TIMING.
Check out HST and Max-OT. I just posted a new link for Max-OT, a pdf file, so you won't have to register with AST to get it. Check it out at the top of this board.
