My Experience
Ran it back when it was legal (a doctor prescribed it to me for weight lifting! Imagine that!). It is simply the best deal in the world when weighing costs vs. benefits.
Used Deca @ 200mg/wk. Everybody says that's too low, but I had great results with it. 165lbs. to 185lbs. I wasn't interested in huge guns, etc. Never had any side effects including sex drive problems (but, hey, I wasn't getting any anyway).
