IRVINE, Calif., Aug. 31 /PRNewswire/ -- St. Louis Cardinals' homerun hero
Mark McGwire takes a teeny little pill with a five-syllable name, and suddenly
sportscasters and reporters around the world are tripping over the
tongue-twister of a name. But androstenedione (andro - steen - DIE - own),
andro for short, is not just being mispronounced. It's being misunderstood by
most of the people talking about it.
"There are some common mistakes being made as people report on McGwire's
use of androstenedione," says Patrick Arnold, an American chemist who
developed andro into a pill that is marketed in the U.S.
Following are the two most common misconceptions Arnold has noted:
MISCONCEPTION #1: Andro is a drug. It is not a drug, and it is not
regulated as a drug. It is a legal, over-the-counter substance.
MISCONCEPTION #2: Andro is an anabolic steriod. Andro is a steriod
compound. The term steroid simply means a structural configuration to a which
a wide variety of compounds, including cholesterol, belong. When people hear
the term steroid, they are thinking of an anabolic steroid which is related to
tissue-building, and sex-specific testosterone activity like deepening of the
voice, facial hair, etc.
Another point of difference: Anabolic steroids are pure testosterone,
injected directly into the body in any quantity; andro, on the other hand, is
a precursor to testosterone. The body converts andro into testosterone
naturally, so that for a few hours andro will raise the amount of testosterone
in the body by approximately 15 percent.
History behind andro
Andro was first used as a performance enhancing supplement by East German
scientists in the 1970s. Athletes snorted it through nasal spray to enhance
The Germans patented andro in the U.S. in the 1990s, but only for nasal
usage. At about that time, American chemist Patrick Arnold developed andro
into a pill that is being marketed today through a company called Substrate
Solutions, a division of MET-Rx Engineered Nutrition.
MET-Rx is owned by Dr. Scott Connelly, a leading physician in nutrition
and sport supplements who established the Connelly Lab for Applied Nutritional
Science at UCLA. Arnold and Dr. Connelly are currently developing a more
effective second-generation andro supplement called androstenediol. Lower
total dosage requirements and reduced potential side effects are important
goals of their research and development efforts.
Arnold said this second generation supplement works through a different
enzyme than the original andro, and can raise testosterone levels up to

He is also a visiting lecturer on nutritional physiology at UCLA. Dr.
Connelly is currently collaborating with researchers and scientists to study
how better nutrition can increase muscle mass and strength, improve the immune
system and enhance overall health.
