McMahon made his commentary debut in 1971 when he replaced Ray Morgan after Morgan had a pay dispute with McMahon's father, Vincent J. McMahon , shortly before a scheduled TV taping. The elder McMahon let Morgan walk instead of giving into his demands and needed a replacement on the spot, offering it to his son. For the younger McMahon, it was also somewhat as a compromise, as it allowed him to appear on television. McMahon wanted to be a wrestler but his father would not let him, explaining that promoters did not appear on the show and should stay apart from their wrestlers. 
To tell the truth, TRT is unnecessary in most cases. However, too many bodybuilders do not know how to use proper PCT and/or are too impatient to wait for their bodies to recover. Sometimes, bodybuilders use the “low testosterone” excuse merely as a means to obtain legal, pharmaceutical-quality steroids from a legitimate pharmacy or compounding pharmacy. In other cases, TRT is just a euphemism for low-dose steroid cycles involving supraphysiologic dosages of testosterone up to as much as 400 milligrams or more of testosterone esters per week.
