b. Prohibited Substances
The WADA Code provides for the publication of a list of prohibited substances
that “are prohibited as doping at all times (both in-competition and out-of competition) because
of their potential to enhance [athletic] performance.”543 The list includes categories of banned

542 According to Professor McLaren, another collection issue could be the program’s rule
requiring samples of less than 78 milliliters to be discarded. If a player’s sample is smaller, it is
discarded; if second and third samples similarly are smaller than 78 milliliters, those samples
also are discarded and the player is excused from the test for that day. This could permit a
concerned player to evade detection.

substances, including anabolic agents (such as steroids), hormones and related substances, agents
with anti-estrogenic activity, and diuretics and other masking agents.544
To provide flexibility to address the newly-developed performance enhancing
substances, the prohibited list bans substances that are not named specifically but that have a
similar chemical structure or similar biological effects. In the case of steroids, the 2007 WADA
prohibited list specifies 51 separate steroids by name but also bans the use of “other substances
with a similar chemical structure or similar biological effect(s).”545
The Major League Baseball joint drug program includes specifically prohibited
steroids. Human growth hormone also is listed as a prohibited substance. The program includes
a different formulation of a catch-all provision, including among the prohibited list “anabolic
steroids that are not covered by Schedule III but that may not be lawfully obtained or used in the
United States (including ‘designer steroids’).”546
Several types of performance enhancing substances that are included on the
WADA prohibited list are not prohibited under the joint program including certain types of
diuretics and other masking agents that can be used by athletes to avoid testing positive.547 Rob
Manfred informed us, however, that each year the Montreal Laboratory provides the
Commissioner’s Office and the Players Association with the updated list of diuretics and
masking agents and tests for them.

547 See 2007 WADA Prohibited List, supra note 544, at 6. The joint program also places
the burden of proof on the independent program administrator to show that a player took a
particular masking substance (such as a diuretic) with an intent to avoid accurate testing.
