Ahh, that's why they called him Lance "arm"strong haha I geuss it could help though, weird, but plausable.
Could be, One of the actions of Viagra is "increased exercise tolerance", i will not go into the exact mechanisms but similar mechanisms that cause it to cure erectile dysfunction also make it work to increase exercise tolerance... So banning this substance is a def possiblity... As was mentioned above...could be rather embrassing to get busted for this...as opposed for regular old roids...haha
Would hate to be on viagra while im standing in my underwear at the weigh ins with Arianny next to me LOL
