Llewellyn's books "Anabolics" and "Underground Anabolics" are packed with information...most of the core knowledge that will ultimately inform a potential or existing user of AAS. What's better, it's informative without having to sift through thousands of threads filled with stupid questions (yes, there ARE stupid questions), even stupider answers, misinformation, and straight up lies.
Oh, sure, the Llewellyn books aren't going to allow you as a reader to access discussions about motorcycles or pornography, nor do they delve into the really important questions like whether a young Lou Ferrigno could beat Superman in an arm wrestling contest. Nope...not in there. The books are just packed with information--very little entertainment value.
