I found an ‘iDose’ of ‘viagra’ here. Be warned, it’s really fucking annoying, and it’s nothing more than an FM synthesis trick – it’s a PWM wave playing a continuous tone that increases in pitch from low to high, while that is being modulated by a sine wave at about 4 Hz (you can actually count this if you listen, but turn the volume down and don’t bother with the whole thing) – this same trick is used by drum and bass and jungle and music similar – surely you’ve heard a dance track that has that “wub wub wub” type bass going on? This is the same fucking thing, and it’s lamer than shit. The only thing at work here is the placebo effect, if at all.
P.S. doesn’t work, I don’t have any boner, let alone one lasting for four hours 
. Sorry USA Today, you’re the Fail Whale Today.
