Exactly what Deige said. :thumbsup:

If your home tests show a positive with the first-mornings void, then stop all exercise 3 days before the scheduled U/A, and be as lazy as possible to avoid releasing a bunch of THCA into your bloodstream (as a result of fat cells burning), which will end up in your urine to be detected. And consider..

a) Substitution - either with a clean persons sample or synthetic

or

b) Dilution - Begin your creatine-loading 3 days before the U/A in preparation to use dilution techniques. Follow both the Substitution and Dilution threads linked to Deiges signature.
