The idea of being able to stop ageing is indeed very noble, but how do you plan to really achieve it. You say users would be able to take part in clinical trials, does this mean you have already found some unique techniques of anti-ageing. Also this project is very ambitious and is directly related to people's health, which means you need to strictly adhere to govt. guidelines. Have you got the required permissions?
We are planning to use methods and information that have been tested in a lot of clinical trial and described in a articles at PubMed. For example, there is dependance between IFG-1 and aging of the body. And there are assumptions that a diet with low callorage can make your IFG-1 lower. So we developed a panel of biomarkers, that you should check before and after diet (we alreafy have a few). And if the assumptions above were right we will see correlation. So there will be no doubts, which of diet is best for most of us. And thats only one example of trials we want to develop.
