No it won't. The test will likely be them assessing your testosterone to epitestosterone ratios. If they are out of range which is indicative of steroid use, they will then test for metabolites. They don't just run test for every compound initially cause its too expensive. So they check to see if there is probable cause to look further. I don't know the half life of Tomas, but I'm pretty sure it is fairly short. So it should be clear a month later when you are to take your test.
