Although I do agree, to an extent, that testing will always lag behind new drugs; it is often not the issue. In ZA, there are well known drugs that SAIDS and WADA simply don’t test for, as its too expensive. At least in some local cycling circles, this is known and discussed. So if one wants to dope, do so with substances that are too expensive to run in random tests. For athletes with a passport, its somewhat of a different story.
