That 'jacked kid,' who's oddly muscular frame has become 'meme-worthy' may be fun to watch, but there's a chance that he has a rare genetic disorder that forces muscles to develop early and makes kids unusually strong.
Myostatin Mutation or Myostatin Deficiency, aside from being an affliction that everyone wants, is a lack of a genetic level protein called Myostatin; the stuff that tells your skeletal muscles (those that make you move and do awesome feats of strength) when to stop getting bigger. If you don't have Myostatin, then your muscles get bigger and you get stronger.
Of course, it's just an assumption but it sounds a lot like this case study from the New England Journal of Medicine that shows unusual muscle development in a child just hours after birth. Yep, dude is jacked before he's even eaten any solid food.
It happens in animals too - cows with the disorder look like this -
We know what you're thinking - side effects. There must be something horrible that happens to these mini hulks, like maybe their heart explodes when they turn 12, or the whole thing reverses and they end up looking like a skeleton with baggy skin...
There are no proven side effects as yet and it seems that most 'sufferers' live long and awesome lives as buff supermen. The only thing that's different is their ability to get strong without trying.
Sadly, you can't catch a genetic disorder and attempts to duplicate the effects through supplement regimes have come up short. But all is not lost - there is heaps of ongoing research and it's hoped that there will be a product on the market that can adjust your Myostatin within the next few years.
In the meantime, spare a thought for the jacked kid, he's doomed to a life of being buff, loved by girls and never having to go to the gym.
