I still don't know why someone would want to get a full camp used to a tunned up body to get to the real fight feeling like a spark plug is misfiring. Why don't train the way your body will perform fight night the whole time and then be aware about how much pace and strength you can implement in the match far in advance. It's like training to race in a car featuring drag tires to participate in an event where only radials will be allowed. Or as they say in aviation: "Train like you fly. Fly like you train."
The TRT cheating aspect comes purely from the comission allowing it or not.
Random test fighters to check their levels are normal an forget if they are on TRT or not. Normal levels is all that matters. I think it is as simple as this.
"Although no one can go back and make a new beginning, anyone can change now and make a new end."
