It depends upon type of test. If it is a pre employment drug test then steroids are not tested in these tests but if the are testing for sports then steroids can be detected.
I often read the news that many athletes use steroids to get better results. To be honest, I don't support it at all. I also bet on sports on one of the betting sites that I found here https://www.mightytips.com/bookmakers/norway-betting-sites/. Sometimes this kind of news confuses me and I don't understand what kind of bet I should take.
