Okay. 3 days before your scheduled U/A, take one more home THC test. When testing yourself, use the first urination of the day. If youre still failing the home test, then make an effort to find a clean sample from someone. It would also be a good idea at this time to begin creatine-loading and other preparations for dilution, in case a clean sample cannot be obtained (refer to the Dilution 'sticky' thread).
