FYI it is easy to make new steroids. You see, the molecule of human testosterone has many "ports" to bind other molecules to. So all they have to do is find new chemicals to attach to the testosterone. The people that issue drug tests have to know what the test is looking for before they can find it. So unless they get tipped off about what the chemical looks like, then they won't know. So it is very likely that they will have more of 'em in the future if not already.
