Ultimately, the following scenarios remain plausible in regards to Colabello, oral turinabol and the MLB positive drug tests: The athletes in question took oral turinabol after purchasing it online as part of a doping regiment that had worked in the past, believing the window of detection was still narrow. There could be contamination coming from dietary supplements, or their ingredients, that resulted in trace findings for the long term DHCMT metabolite in the various athlete urine samples. Finally, there is the theory that a common genetic anomaly, or another substance related to DHCMT that is present in the environment, could produce the same long-term DHCMT metabolite used for detection in trace amounts in some athletes—remote possibilities that have yet to be demonstrated.
"Let me say first and foremost that I have never knowingly taken a performance enhancing substance of any kind," Deetz said in a statement released by the Major League Baseball Players Association. "I come from a small town, and know how fortunate I am to call myself a professional baseball player. I would never jeopardize that opportunity, or betray those who have supported me along the way, by trying to cheat in order to gain an advantage. As I explained to the arbitrator in my appeal, I have no idea how I could possibly have tested positive and although I am disappointed with the outcome, I will abide by his decision."
