Ditto! Skar has already laid out some good advice so my .02 cents is, yes, get some pure BCAA powder. The amino tabs are fine for your basic amino supps but not for BCAA supplementatoin. Powder is best and I usually take 10gm's AM with whey shake, 5-10gms pre-workout and 5-10gms post. I've noticed nice results.
Body Fortress makes a pretty solid product and the price is always right. I've used thier Whey and preworkout drinks (super nos blast) in the past and was pleasently surprised.
