This ad shows up on some gay sites.. Appears the stuff is from India. I'd be careful about buying prescription type drugs from there. I'd only trust stuff actually manufactured here in Canada or the US, Australia the UK and other Euro countries.
There are some websites purporting to be "Canadian" selling drugs but in actuality are not, they're overseas somewhere.
Anyways,, try some of these generic Viagara's and let us know what you thinkhttp://thesecuretabs.com/viagra100mg.html?id=277⊂=001
