be carefull about the steroid chem books, many are full of bro-science... i'd stick with Endocrinology books. I scour used book stores and thrift stores and get the OLDEST books I can find since they tend to have more info on steroids in them.. a lot of times OLD obscure steroids too. my wall/bookcase used to be FULL of them, and I believe the most I paid for any of them was like $3!.
i agree the steroid handbooks are only good for getting a first idea.
sometimes they have massive errors in them which are either never corrected or with next release-update, a decade later.
i remember clearly, 15years ago, the one most popular steroid handbook, not one hint to the possibility of tren causing bitchtits, let alone how to "prevent or avoid)it.
meanwhile for the other steroids,theres been explicit warnings etc.
but 1 thing i still wonder about how have builders found out about arimidex so fast after its been released.same thing on that,in the first books, this was never mentioned.now it s one of the fav estrogen blockers out there.
