With regard to Curlin’s performance in Dubai, it should be noted that the horses he faced over there were incredibly sub-par. indicative of the state of the older male dirt handicap division this year. Both “races” were nothing more than well paid public workouts. With the retirement of so many of last years top 3 year olds including Street Sense, even a temporally steroid free Curlin could beat the plugs he faced there in a $4M race. This was a smart tactical move by his connections since the BC is in California this year on a synthetic surface in a state that will soon ban the presence of anabolic steroids in a horses’ blood on race day. IMO, there is little chance Curlin will race in the BC classic. Steve Assmussen, Curlin’s trainer and Rick Dutrow, Big Winstrol’s trainer, both annually vie for the title of top “super drug trainer”. Just Google their names if you want to read about their sordid histories, replete with many suspensions for administering performance enhancing drugs to their horses.
This is a great question that, unfortunately, cannot be answered in just a couple hundred words. There are important issues that focus on educating one's self prior to embarking on such a course of action, particularly the downsides of using steroids – the side effects, the proliferation of fake gear, getting off of them, getting blood work done, etc. And, the fact that buying, selling and transporting them is (in America) still a felony, not to mention banned by all sports federations. All very important salient issues that require a lot of space to do justice.
