Query: Good Book!

I cant imagine how anyone could read this book and walk away without learning some valuable lessons. It is a very exciting book that covers many topics. I am happy I got it. Its a great tool if you are thinking baout using steroids and even better if you really are using them. Not to say that i think using steroids is ok. but if you are going to use them you should be as educated as you can about them. This is a good book for that.
