I dunno none of my friends really seem to know anything other than what I tell them, I don't think the average body builder chooses to be an academic and spend a bunch of time doing research. I compare the reading and cross referencing I do online to be a lot like college classes, but without the credits. I have spent hundreds, if not thousands of hours researching all for self gratification - so wanting to know this information is because you're passionate about it, and not a lot of people want to take the time to understand everything because they're lazy. "Give me a magic formula of nutrition, workout programming and drugs to get me what I want" or more commonly "give me a magic pill." There isn't one, its hard work, dedication and budgeting what it takes to get there.
