Yeah, um all of these pills are crap.
Here is the ingredient

nausea, diarrhea, euphoria, headaches, epistaxis, high blood pressure, low blood pressure,

Tribulus Terrestis Extract Some users report an upset
stomach, which can usually be counteracted by taking it with food.

ExtenZe DOES contain Yohimbe which can kill you if it makes your heart rate go too fast. (Which mine beats too fast so this pill would kill me.) They say how safe it is but they don't warn you about the yohimbe in it. They're asking for a lawsuit, IMHO.
