Objective: To determine if steroids containing over-the-counter (OTC) dieta
ry supplements conform to the labeling requirements of the 1994 Dietary Sup
plement Health and Education Act (DSHEA).
Design: 12 brands of OTC supplements containing 8 different steroids were r
andomly selected for purchase in stores that cater to athletes. There are t
wo androstenediones (4- and 5-androstene-3,17-dione), two androstenediols (
4- and 5-androstene-3 beta, 17 beta -diol), and 4 more are 19-nor cogeners
(19-nor-4-and 5-androstene-3,17-dione and 19-nor-4- and 5-androstene-3 beta
, 17 beta -diol).
Main Outcome Measures: 12 brands of OTC anabolic-androgenic supplements wer
e analyzed by high-pressure liquid chromatography.
Results: We found that 11 of 12 brands tested did not meet the labeling req
uirements set out in the 1994 Dietary Supplement Health and Education Act.
One brand contained 10 mg of testosterone, a controlled steroid, another co
ntained 77% more than the label stated, and 11 of 12 contained less than th
e amount stated on the label.
Conclusions: These mislabeling problems show that the labels of the dietary
steroid supplements studied herein cannot be trusted for content and purit
y information. In addition, many sport organizations prohibit OTC steroids;
thus, athletes who use them are at risk for positive urine test results. I
n this article we provide the details of the analyses, a summary of the ste
roids by name and structure, and information on the nature of the positive
test results. Athletes and their physicians need this information because o
f the potential medical consequences and positive urine test results.
