Make money by being a guinea pig for big pharma?

I have toyed with the idea of  enrolling in one of these studies for years. While well aware of the dangers of  the “drugs” that they will be testing on you. (The results from these studies is so bad that half of them are routinely just thrown away and not included as actually happening- which tells me these safely studies” are close to useless.)  This one looks promising as it is a “nutritional supplement” but alas there is an age limit that disqualifies me.  I’ll keep looking the money can be pretty good,  often over $200  a day.
