Most of the athletes are on it for the recovery purposes. Imagine after a hard tennis match your body recovers twice as fast as someone who isn't on some juice. If you have an injury the recovery process is also sped up. The downside and what gives it away with rugby players is how often they tear a bicep or a muscle. Muscles are a lot weaker and it takes something special to tear a bicep unless it is a steroid one. They are all on it and that photograph just proves it as they are all fake. It will be interesting to see a list of injuries for each player over the next five years and 99 percent will be muscle related.
