I watched something on Discovery channel this afternoon where they were taking chunks out of a salamander to get it to regrow entire limbs even where the original was still intact. From what they learned in doing that they made a virus like concoction of IGF and injected it site specifically into mice, who when trained grew about 50% more muscle. They said it was only a matter of time before they perfected this in humans. Of course I was looking at this thinking about PE.
