I know this is an old post but i needed to clarify some things. It will NOT SHOW UP! i use the patch for 3-5 days prior to a probation urine test to get me through. It works every time!
does not show on a urine screen. A special expensive test is required because it is a synthetic opiate
. Its the same thing as Methadone
in which they have to specially test for because that is also synthetic and will not show as opiate on the test.
