I make it a point not to put anything in my mouth with more than one ingredient. That's normally because I'm generally horrified by the list of ingredients on most processed food/drink I happen to read, but then again I'm quite the nutritional nazi.
Although, hoax or not, considering most people in the Western World consume milk or milk products which by definition, contain bovine hormones, consuming the sperm of a bull probably isn't much worse than drinking milk.
