These are definitely not fringe claims. (They are not claiming you'll become immortal by taking the medicine). Who decides what fringe claims are? Are you claiming that you are better than these researchers? Before a research work (like http://www.ncbi.nlm.nih.gov/pubmed/15602821 ) gets published, it goes through a review process. They don't publish junk work or fringe claims. And I am not saying it will be the next breakthrough. All I am saying is you need to give due credit to research work done by reputed institutes. 

 You don't need to believe in claims, but you should reserve the right of expression by others about genuine scientific works (which also satisfy wikipedia's policies). I may not agree with you, but I fight for your right of expression. Here, you are just deleting everything and bleating 'these are fringe claims'. 

 You are not agreeing to reach a consensus. If you believe in net neutrality, then you'd be willing to add to criticisms, not deleting the main text. I will revert back the changes. I can't agree to deletion of patent links and links to publications from scientific journals, which are not objectionable to Wikipedia's policies. Thanks.
