Some trainers know that their horses will test negative post race because they are being treated with fast clearing PEDs. Can you say Nitrotain? Since there is no random out of competition testing done in the US, you can train your horse on a powerful anabolic steroid like Nitrotain, stop on Tuesday and race with impunity on Saturday. This allows you to turn an ordinary 3yo maiden claimer into a multiple G1 winner or a good 3 yo sprinter into Dr. Fager!
