I read or heard somewhere that a study was done on the prison population and the study showed that most prison inmates produced larger amounts of testosterone than normal everyday folks. Of course this was because of the environment that they live in,
I had a friend who was a prison guard here at a Penitentury, and he told me about this prisioner that was soo big, that they couldn't get hand cuffs around his wrists. This guy was naturally huge and lean, and did not work out much to my understanding.
I do believe that prisioners produce more testosterone hince that is what makes them lean and big.. just my .02 worf..
