The best thing you could do to learn how to build muscle is to go to a big bodybuilding forum and just do whatever bro-science they spout. I've been following bodybuilding forums and casually looking at research for many years, and invariably the bro-scientists are way ahead of scientific proof, in terms of methods and techniques, all the way down to finicky details. You'll also get the truth about what you can and can't do with/without anabolics.
Edit: I see that the author is here. It's not a bad guide, good design etc, but frankly it rubbed me the wrong way to basically read "I'm right and everyone else is wrong, because I researched", without having a highly impressive build to back it up. Even professional body builders don't prescribe certain techniques/methods as gospel.
