i dont need to do research...its just my preference. why should i have to defend my personal preferences anyway,i prefer not to take them,why do i have to justify that? couple of my friends had liver problems and another had appendicitis not too long after they started getting heavy into supplements,not saying that it was the direct cause but i just dont want to take them,big deal. i dont need to back up anything i said,its an opinion...thats like trying to defend why you dont do crack,i dont need to do research on it,i just dont want to do crack,haha
