His genetics are pretty good and what he used to build that size isn't needed to maintain, I doubt he's using more than a few 100mgs of test and a few ius of HGH. He would have his life expectancy front and centre, plenty of people earn money off him being the rock, his advisors would be conscious of finding the right balance of maintaining their cash cow for as long as possible . Appreciate most will disagree. But he looks to be in good health.
