Tell that to 52 year old Kevin Levrone who looks ridiculously amazing not only for a guy of his age, but of any age.
dude hasn't juiced in 13 years and is mega dosing for the Olympia, he actually is a perfect example for what I was saying, he retired from bodybuilding and went back to normal athletic size, he didn't continue to keep a massive muscular build post retirement, he wasn't taking in 500 grams of protein a day after retirement, it's just not maintainable, I give Levrone props, he is one guy who didn't let his build be his identity. At 50 I would rather look like this then a bulky meatball any day, this dude is a 50 year old endurance athlete.
