I have a nagging suspicion that some of the people I have seen at some tournaments may be on something. Tournaments are suppose to be fun and there is no money to be made (most of the time). The will to win probably drives people to abuse their bodies like that. It also deters me from attending. All I need in my life is a roided up person heel hooking me to the point of limping for the next several weeks.
No one will implement testing at tournaments because it costs too much money. I don't think anything can be done to avoid the PED people.
