The thing is… this is like dyslexia. Before science had a term for it, it existed and people didn't realise. The same is true for these mutations. They are not brand new 21st century craziness. It's very likely this german kid is just the first kid to have been diagnosed with this condition from birth. If Wheeler was born today, it probably would be the same situation. As I say, I'm sure this has happened before, so this is great fodder for growth stories, but in real life, it most likely won't amount to ubermensch.
Well I wasn't trying to claim that. As they say in the first research, there seems to be NO link between this polymorphia and muscle growth – and Flex was only one of 40 participiants, so it's not extraordinary rare freak of nature kind of thing – but the second one might have. So it's more complicated than just a lack of one growth factor.
There are some myostatin blocker out there, but so far those seem to be just sugar powder with fancy name. No results whatsoever.
So with given data I can't really claim anything in one way or another. This kind of people most likely have been throuhout the history, so as you said, it's not a new thing. But are there different levels of this mutation, I don't know.
Anyhow this is off-topic so I guess I've said what I wanted to so back to the topic. Maybe to write a muscle growth story about this matter.
