If you do some reading here you will see that you are doing pretty much everything you aren't suggested to do.

You cannot detox yourself of THC. Pectin does nothing, downing tons of water other than 2 hours before the test does nothing, cranberry pills do nothing, AZO pills do nothing, grean tea does nothing. It pretty much reads like a how not to pass a drug test.

The only thing you can hope for with your plan in a negative/dilute which is not a passing grade. You don't have enough time to load creatine.

The only thing that is going to help you this late in the game is subbing. I hope your head shop has some good synthetic urine. Good luck.
