Sand Lapper

Ok so I'm 39 and new at reviewing using some helpful steroids...been lifting weights naturally for some time via circuit training - trying to put on muscle mass and tone up at the same time. Need energy and stamina, but don't want to start on something that is really bad for me. I've tried reviewing forums and blogs, but am confused as everyone speaks a language I don't understand when it comes to understanding steroid use....Anyone know how to simply get started?
