hey guys, I was listening on the radio, and apparently viagra is becoming a big thing in the sports "performance enhancing substances" world. anyone used this for a lifting supplement? I'd figure it works 5x better than N.O. but once you see a nice looking lady, the workout's over, if ya know what i mean I've never heard of this before but a lot of the baseball players that were busted for using steroids turned out to also be using this. your thoughts?
