It is not a matter of chilling - it is a matter of caution and concern.
For every thing that showed positive results in rat studies, only a small fraction of them proved to have any use with humans. Rat studies is merely a very early step along the way. DCA is unproven for use in humans and it is proven to have side effects. given that I disagree with a company jumping on the bandwagon of premature results and marketing it. Just as I disagree with you posting a link in your message on where to buy it.
I am light years away from even pretending to know everything and am still learning every day. The day I stop will be the day I cease to exist. One thing I have learned, at least part, is to proceed with caution. Even then I still make mistakes, and can understand when others jump a bit early. Cancer is a horrible plague and most of us are more than anxious to conquer it.
I think that if we look to nature we will find the answer - we have looked at the endless string of broken promises with man made drugs too long as it is.
