Free Trials

I recently saw in the papers an ad requesting for Caucasian men to come forward to a research company to participate in a diet supplements review programme. In exchange, they will receive a free supply of diet supplements during the trial period and blood tests. While it might sound attractive for someone who's trying to lose weight, I do have some reservations about trying something new that is untested and which I don't know the health impact of. Losing weight is good but maintaining good health is a lot more important!
