We can consider jucie cheating in general. But were do we draw the line for what is considered juice? Is it just because it is illegal in human sports? One example is that if you compete in France with creatine in your system you'll be considered on juice. But not were I live. Ofcourse testosterone can be considered cheating, but we use way more than that in the dogs. There will always be impossible to lay down rules unless there is testing. So I guess it's up to each individual how much to cheat himself and his own dogs.
