Listening to NPR, heard a snippet about "mighty mouse" (using Myostatin inhibitors to combat muscle wasting diseases). Which led me on a search and I found this article:
Has there been any studies on dieting/lifestyle that can linked to regulating Myostatin?
While I don't know much about Myostatin, this article brings up an interesting debate. . . should there be testing for those people who might have the 'genetic mutation' and their bodies produce less Myostatin?
