If your retest is scheduled for Wednesday of next week, you can start exercising and get on a fiber-rich diet. At least 3 days before your scheduled U/A, take one more home test using the first urination of the day. If your home test is once again positive, then stop all exercise and be as dormant as possible until after the scheduled U/A.

Exercise burns fat cells in which THC is stored in. Anytime fat cells burn, the stored THC metabolizes into THCA and is released back into the bloodstream. The kidneys filter the THCA metabolites from the bloodstream and deposits them into the bladder for the eventual exit.

So for those 3 days, you want your body to go into "storage mode" - stop burning the fat to prevent a bunch of THCA from being released, which will end up in the urine to be detected.

When utilizing dilution techniques, be sure to begin your creatine-loading 3 days before the scheduled U/A.
