This article is a little long but its an excellent read. this dude did a cycle of steroids so he could write about it and its amazing to read what it did to his body in such a short time.
i thought man boobs was the worst of it (and it still might be) but this guy went through the ringer and apparently everything that happened is pretty typical.
