How to go back to IOS 6 on Apple iPhone 4s?

I really want to go back to IOS 6.1.3, It's not that i don't like IOS 7, it's because it is so much slower now then when it was on IOS 6. I did not Jailbreak and do not have any shsh Blobs, is there any possible way? Even if its hard: l, I have only found ways for the iPhone 4, not 4s.

It can't be done on the 4s. That's why you only found ways to do it on the iPhone 4 and earlier.

Apple designed iOS 7 for the 5s and they knew older versions of the iPhone wouldn't be powerful enough to run it so they'd run slow. They did it on purpose to make people want to buy a new iPhone.
