Vince, as has been said over and over - interest by the authorities in the blackmarket is primarily with respect to narcotics and organized crime in general; performance enhancing drugs are a small piece of the pie and are mostly of interest to WADA. There is a gym on the 'north shore', of similar name, not far from where you are Vince where a bunch of stuff went down to that extent some years back (the gym owners were not involved). An employee at the Government lab, who performed testing for the 2000 Olympic games was dipping into certified reference materials (GH, EPO, Insulin - although tests for these were not validated at the time, as well as steroid hormones) and these went into the hands or australian-arabic gangs that were involved in anything from supplying narcotics to violent crime. You see, once systems are in place it really does not matter what items are traded. Gyms / hormone trade provide a nice portal to connect with and trace such crime networks.
