companys usually only test for drugs (coke, meth, heroine, marijuana etc..). they rarely test for steroids, because as it was said before, it is expensive. however, if they do do a steroid test, your "tren" usage can create a false positive and they would not know what it actually is unless they test for the exact compound. also, the bronzey color, blame it on ur multi. lots of b vitamins can do that.
