I have done some reading awhile ago. If a person lacks the myostatin gene, which indeed does limit muscle growth, they tend to be leaner, more muscular and stronger. I have only heard of 2 reported cases and one is here in the U.S but is a small child. It has been bred into a dog known as a bully whippet and has been coined “double muscled”. It is also bred into certain cows but the name escapes me. The dogs and cows are muscular monsters though. As for the bodybuilders, I cannot say if it is true or not but it is a very rare genetic condition. I also believe there are two variations of the defect.[/quote]
The name of the cows was Belgian Blue, and yeah they were crazy looking.
As for the myostatin I remember reading years ago about Flex Wheeler having little or no myostatin gene, and there was quite a bit of publicity towards it. So this claim I doubt is valid.
