I cited the source in post #18, but thanks for stopping by. I'd stop questioning my sources anyway. Have you ever checked out any of the FAQs here on Sherdog? Many of them reference one website, that's it. So if you want to question me, start by questioning this site in general.
My case in point is the Beta-Alanine thread.
http://www.sherdog.net/forums/f15/beta-alanine-next-creatine-606832/
That whole thread is based off of one testosterone nation article and has over 650 posts from lemmings believing it is the best thing since sliced bread.
I'm not trying to be a dick but it seems that too many people hide behind the "source?" argument when they disagree or don't want to believe what someone tells them. Asking for a source is fine, but if you are sitting at a computer, LOOK IT UP YOURSELF.
