Well, actually, that's always been the standard (and appropriate) scientific response to any new claim. We're all from Missouri, so to speak; "Show me" is how science operates.

GLENDOWER: I can call spirits from the vasty deep.

HOTSPUR: Why, so can I, or so can any man;
But will they come when you do call for them?

(Shakespeare: Henry IV Part I: Act 3)

I can, however, believe that it doesn't get a lot of funding or support because the big pharmaceutical companies haven't figured out a way to make money from it. Also, snake bites may be a big problem in rural South America where people don't have any money, but outside of a handful of backpackers and Park Rangers, it is probably not perceived as a big money-maker for those companies, even if they could patent it.:-(

Keep working at it. Maybe you could get Taser International to invest - they could use some good publicity these days. (Hey, that's not a joke.)
