Anti-doping expert Don Catlin believes the numerous NFL players who tested positive for the diuretic butemanide may have unknowingly used dietary supplements tainted with the drug. (”Alleged use of old-school drug surprises experts,” October 29).
“I’d love to know,” said Don Catlin, a renowned expert who ran America’s first anti-doping lab. “But that’s why the first thing I thought was, ‘They take supplements all the time. Every athlete does. Maybe it’s a bad batch of supplements.’”
We reported previously at Catlin’s bewilderment at the intentional use of butemanide by NFL players as a masking agent for anabolic steroids. There were several plausible indicators that a contaminated supplement could have been the culprit. Experts are indeed baffled by the presence of an old and dangerous drug in anti-doping samples.
Two professional soccer players tested positive for the banned performance enhancing substances androstatriendione (ATD) and metabolites of the anabolic steroid boldenone according to the MLS. Red Bulls Jon Conway and Jeff Parke were suspended and fined ten percent of their respective salaries for violating the MLS substance abuse and behavioral health policy (SABH).
According to Red Bulls manager director Erik Stover, both players said “that they ingested an over-the-counter supplement that unknowingly contained a banned substance.”
The statement seems to imply that there was no indication that the banned substance androstatriendione (ATD) was listed on the label of the OTC supplement product. Most likely androstatriendione was listed with a synonymous chemical name e.g. 3,17-dioxo-etiochol-1,4,6-triene or 3 17-keto-etiochol-triene. Ignorance or naivete regarding supplement ingredients by drug-tested athletes rarely succeeds in exonerating them from anti-doping policy violations.
Products containing androstatriendione (ATD) are very popular in the sports nutrition marketplace. One of the most popular products in this category is Gaspari Nutrition’s Novedex XT. Novedex XT is, by all accounts, completely legal and DSHEA-compliant with all ingredients fully disclosed on the label. But if the anti-doping policy in an athlete’s sport has banned androstatriendione (ATD), then athletes would be wise to avoid all OTC supplements containing any and all modified or derivative versions of 1,4,6-androstatriene-3,17-dione (ATD).Â
Four of the eight NFL football players whose names were “leaked” as having violated the league’s policy on anabolic steroids and related substances were caught using the diuretic Bumex (bumetanide). New Orleans Saints running back Deuce McAllister and defensive ends Will Smith and Charles Grant tested positive for bumetanide as did Houston Texans deep snapper Bryan Pittman.
Reports of a “rash of positive steroid tests” in the NFL by news websites here and here and here and here are highly misleading and false since none of the players are alleged to have tested positive for steroids by the NFL. Nonetheless, MSNBC stated that one player tested positive for anabolic steroids with the headline ”Report: Saints’ McAllister positive for steroids“, but deep in the article reported the truth that it was bumetanide. There are even plausible indications these may have involved inadvertent doping from weight loss supplements tainted with bumetanide.
