If it's not tested, I say no... Just as in bodybuilding, powerlifting, isn't just about the body... It's about the brain and science... A lot of what makes some competitors better is the ability to gather information and apply that knowledge to their advantage... Take bodybuilders for example, it's a lot of trial and error to find out what supplements work best for each individual... There isn't a formula that works for everyone... It comes down to choosing the right diet, supplements and training regimen... Some shine in the area of supplementation, they have the knowledge of what to use and how it will help you gain advantage... That same advantage is an option to everyone else if this event isn't categorized as a natural... Besides some people say that it's only cheating if you get caught... I say it's cheating if you do something that you could get caught for and that's not the case...
