To the unitiated, there appears, visually, very little difference between the top-level professionals performing in 7-year natural competitions and competitions without testing. Is this perception due to:

1.) "hidden" nuances that can only be seen by the initiated; or

2.) natural competitons not really being natural; or

3.) anabolics or other chemicals only quickening the process but not having any noticeable effect on the end-product; or

4.) Something else?
