Stimulants Is it dangerous to combine viagra with propylhexedrine?

[shortjazzdude]

I have a friend who takes propylhexedrine internally. He says he loves the stimulant qualities and the libido increase, though it makes it harder for him to get an erection. So he takes viagra with it. I told him that sounded like a dangerous combination but he says it hasn't caused him any harm thus far.

I'm not sure how well this would work but I know propylhexedrine is a strong vasoconstrictor and Viagra is a good vasodilator. I don't know the risk of mixing dilators and constrictors but If I were you I would research it before taking them.
