All these suggested contraptions will only cause you to fail the test immediately because the NCAA watches you piss. That is, they make you face them as you pee into the cup...I've done it. If they see you trying to fuck around, you fail.
You may be alright dude. Nandrolone will show up if you get a legit test. My thoughts are that not all samples are tested once they are received. I have a number of friends that have passed on cycle.
You shouldn't have been using deca. I only used deca during the season of my fifth year because I wasn't fearing getting a test (long story) until the end of the season. The test came around at the end of the season, but I didn't get picked.
PM Nautica...he is one of the most helpful guys on the board.
