I have a friend that had to take a steroid test during his child custody case and this is what he used before he took his urinalysis. He passed. Now I don't know what compounds he was using at the time. He stopped taking the juice 2 1/2-3 weeks before he had to test.
If you are only concerned about cyp then by all means cut it out as soon as possible. If they test your hormone levels you still might read high if you dont get off the test. Is this something to do with getting a a job or keeping a job? Just wondering.
Best of luck,
K
