Quackwatch is a useful resource, provided that you realize it is overly conservative in anything relating to longevity science. Historically that has been the correct position, but a more careful approach is needed these days. Personally, I'm disappointed with Sierra Sciences for associating with TA Sciences - the whole TA-65 thing is just a herb-selling operation with a cloud of hype of the sort that brings the whole field into disrepute. This essentially means that Sierra now gets lumped into the same category and anything they have to say in the future is looked at with skepticism. Which is a pity, since up to this point they looked like a sane group doing good, albeit slow, science.
