Heavy consumption of the essential amino acid lysine (as indicated in the treatment of cold sores) has allegedly shown false positives in some and was cited by American shotputter C. J. Hunter as the reason for his positive test, though in 2004 he admitted to a federal grand jury that he had injected nandrolone.  A possible cause of incorrect urine test results is the presence of metabolites from other AAS, though modern urinalysis can usually determine the exact steroid used by analyzing the ratio of the two remaining nandrolone metabolites. As a result of the numerous overturned verdicts, the testing procedure was reviewed by UK Sport . On October 5, 2007, three-time Olympic gold medalist for track and field Marion Jones admitted to use of the drug, and was sentenced to six months in jail for lying to a federal grand jury in 2000. 
Not recommending EO. I do not use it. OP said he was using it so I pointed out that he should let it do its job. What you are saying is true for things that are prone to crashing like test C or p, Tren Ace, or any other one of the more difficult to handle compounds, but for test e you really don't need any BB. I will sometimes use 5% BB but I have brewed test e with and without it and there is no difference in PIP. The people who get pain from EO are people who are mildly allergic to it. This is no different from people having a bad reaction to a carrier oil.
