I think it isn't a far reach to assume we all have different levels of myostatin. A guy comes to mind when I was 14 in Jr high school. His name was Vincent - black dude who played football, basketball, ran track. This guy was 15, barely touched any weights - only did the lil workouts required at the school gym during football season. I'd guess him to be around 5'9 and 170ish. Veins popping all across his pecs and delts, in his arms, on his quads, crazy V taper - it was insane. He looked to be 6-8% bf - I mean the dude was friggin ripped all the time. If this guy ever worked out, no telling what he coulda did. There's people out there like that and yet never even think about getting into bb or lifting weights. Crazy genetics just going to waste. I think guys like this have a lower level of myostatin than most - the anomalies, kinda like how most use only 5% of their brain, but the freaks like Einsten who they say perhaps had the capability to use 8-10% of his.
