If you're a professional fighter, I'm assuming that you get drug tested for steroids. If you do in fact get tested, then don't touch deca with a ten foot pole. I'm an athlete who's in the off season, so I'm going to be using Sustanon, EQ, and Dbol in my next cycle, but as the season gets closer, I stick with test prop and other steroids with a short detection time. Then about a month before my season starts I go clean.
