I obviously in my position can't condone or condemn a specific website. I would stick to what is FDA-approved and what is available through clinical trials.
All clinical trials have to be approved by an ethics board.
This offers at least some protection to research subjects. You bring up the use of internal Aldara. Although it is NOT FDA-approved for internal use, the drug is quite effective in treating HPV related warts. Many clinicians have recommended its use internally on a case by case basis. I can't judge whether this would be appropriate in your case.
