I haven't tried it, but heard horrible things about their billing. You have to submit your cc number for the free trial and then they charge you a bunch of times and send out more patches that you didn't order. There's something in the agreement about it. I'm staying away from it for that reason alone!
And, it's probably just another gimmick.
"Look at these people who run marathons. What makes them different to you?...
They have the same bones and muscles as you, the same sinews and organs...
you can do anything you want to, be anything you want to.
The only thing stopping you is you!”
