Testing

Before a weight loss pill hits the market, there have to be weight loss pills reviews so they have some sort of base to advertise their product with. I wonder what kind of compensation the people who try those pills get. Does it border on hazard pay because of some of the effects the pills may have or do the testers take the risks as a grain of salt since they are just testing things? I know I couldn't be a pill tester myself. However, if it's good money, there will always be plenty of people willing to do it.
