This month Scientific American published an article by one of the leading experts in myostatin; H Lee Sweeny. In the article he writes about the therapy he and other researchers have developed. The first drugs that are being tested on humans will be myostatin antibodies. He also mentions myostatin therapies and its use by normal people. Sweeny sees these could be systemic drugs, and not the total gene therapy he and his associates use. He figures the muscle gained would be anywhere from 20 o 40 percent increase. The most intresting item, I thought was that "the absence of myostatin also interferes with fat deposition, making these "double-muscle" exceptionally lean."
