That stuff is a waste of your dough, the only way to get your wanger bigger is to hang weights off of it, hell one night on Conin Obrien i heard Arnold Swercenger(however you spell it) tell Conin he needed to hang a ten pound weight off of his dick.

The only thing that i know that really works to get you dick bigger it to hang weights from it. A little two pound weight can make you dick 1/2 inch bigger, and its ligit. When you have surgery after it you have to hang weights so why not save your cash and just hang weights to begin with.
