Yet you provide zero references yourself. Of course glutamine and BCAAs are in quality powders. That doesn't mean they need to be excluded from a pre-workout supplement. I don't support trying to get all your nutrients from supplements. You need to the right foods as well. That doesn't mean they are evil though.
You seem to have some clue about nutrition Then again given there's no progress photos or anything else related to what YOU'RE doing. The only thing we've seen from you here is negative comments on other's posts. It's good to offer criticism and advice, but your delivery method quite frankly sucks.
