Do they have any available information? Preliminary test? Cured it in vitro, animal models, a few humans? Patents? Any other interesting medical/biological result published?

There are a lot of people that proclaim that have cure for AIDS/cancer/whatever, and many of them blame the establishment for blocking it. The same history appears with perpetual movement machines. Without more proof, probably it just another too optimistic investigator, a scammer or a crackpot.

If true that's so outrageous you can count on me to work really hard for free on their behalf to get the word out.

Can you put me in contact with them?

I am not saying I believe it, but they keep making the claim every time the subject comes up.
