some advise please! Have competed in the past but always natural.Will be entering a contest march 12 2004.I am 43 and have trained religously for 27 years and there are no more natural gains to be had. I have low body fat now at 5'10" 190.I need to start a cycle to compete, when should this cycle end? No testing will be done.Would I also diet down the same as I would naturally?
