Hmmmm....
My son wont be 3 till July and he has been able to pick up and hold 5lb dumbells for 4 months... he leg presses my recliner (14 reps one night) and he can do sit ups with ease. He does them for fun. I have seen him nose dive off the top of the couch onto his noggin and laugh .. then do it again. He eats like hell and is ripped, even has an actual bicep muscle that buldges like a little bodybuilder. His damn hamstring and quads are unbelievable. I was just chalking it up to "he's all boy" or he got mine and my dads genetics but damn after watching this i am starting to wonder. Hell he wears 5 year old clothes already....
How do you know for sure your child has myostatin-related muscle hypertrophy? I do not want my little mini me to suffer some kind of heart problem.
