Ok, I consulted the people who run the contest I will be participating in in July about prohormones and whether they are banned substances and they informed me that they were ok as long as recommended dosages were not exceeded. The one thing they did mention though is that some prohormones will make you test positive for steroids for example N19 use will result in a positive test for nandrolone I believe.
What I would like to know is do the other prohormones cause a positive test and how long should I stop taking them before a contest to avoid this. I will abide by the contest rules as I have no interest in cheating or trying to decieve anybody, I just don't want to test positive for steroids.
Oh and if it's possible could I get the results for both urine and blood tests.
