Works for me! Not sure how much length gains in gonna make but I'm at about 3/4 inch in girth gains already. Aiming for 8x6.

Don't do something if it hurts. If you're already familiar with working out, it's pretty similar, aches are fine, sharp pains are not.
Do it everyday unless your EQ suffers or you're healing
Don't measure constantly. It's a confidence sink. Measure every two months or when you have an awesome "hey! This thing barely fits in my hand!" Moment.
Also like working out, have confidence that you have the power to change your body. I've never been more confident that I have the power to change myself and I've never had faster gains! Is it mind over matter? Or is it just that you're not likely to do what it takes if you're not confident and excited about results! I think it's both!
Enjoy the ride, when you wake up in the morning, and your gear is bigger than it was last week, the biggest it's ever been IN YOUR LIFE, it's an amazing, wonderful feeling. For someone like myself, I'd describe it as borderline miraculous. Keep the faith XD
