The Controversy:
The FDA has asked manufacturers and distributors of androstenedione
to stop selling and manufacturing products that contain androstenedione
by April 12, 2004.
They have done limited research on androstenedione supplements
and concluded that there is inadequate information to establish
that a dietary supplement containing androstenedione will reasonably
be expected to be safe.i
In fact, FDA believes that these products may increase the risk
of serious health problems because they are converted in the body
to testosterone which is an androgenic and anabolic steroid ii.

FAQ:
Q. The studies all tested products
that had over 100mg dosage of androstenedione per single dose, what
about products like Andropower, Testrogel, and Testroxin that only
have 20mg per single dose?
A. Good question, The Study done on androstenedione where
all for higher dosages ranging from 100mg-300mg per single dose.
The scientist who did the study concluded that "As stated above,
if taken in sufficient doses, Andro products will have anabolic
effects." So the question is to define what is a sufficient dose?
20mg of transdermal gel that contains androstenedione should be
enough to give you the extra boost, without the negative side effects.
Q. Male breast? Higher estriaol levels?
Who wants that? How does Andropower™ combat against the effects
of higher estrogen levels?
A. Andropower™ contains a precise formula of 20mg of Androstenedione
and 10mg's of Progesterone to combat the possible side effects of
increased estrogen levels.
Q. These products have been available
for a while, why would the FDA ban them now?
A. Because of safety concerns raised by health professionals
on the abuses of androstenedione-containing dietary supplements
by people under the age of 18.

The Studies:
One 8-week study
on 20 healthy males from 19-29 was done on placebo vs. androstenedione
100 mg three times daily during weeks 1,2,4,5,7,8. They studied
the effects of androstenedione in 100mg in a single dose on levels
of various hormones.
They found that
neither the single mg dosage 100mg dose nor the extended 300mg daily
dosage affected the serum levels of testosterone. They found that
the Men using the 300 mg dosage daily saw an increase in estradiol
and estrone levels by 50%. With the higher daily dosage of 300 mg
a day, the androstenedione treatment reduced the HDL-C (good cholesterol)
more than the placebo.
Study # 2 Leder et. al. (JAMA 2000;
283: 779-782) treated healthy men aged 20-40 years with androstenedione
100 mg daily (n=15), 300 mg daily (n=14), or nothing (n=13) for
7 days. While there was no effect at the 100 mg daily dose, there
was a mean ~35% increase in testosterone in the serum (integrated
over 8 hours) at the 300 mg daily dose. Additionally, serum estradiol
levels (integrated over 8 hours) were elevated 42% and 128%, respectively
at the low and high doses of androstenedione, respectively. Study
# 3 Effects in Women: predominant elevations in androgens
Leder et. Al.(JCEM 2002; 87: 5449-5454)
studied the effects of single oral doses of androstenedione (10
women each received either 0, 50, or 100 mg) on serum levels of
androstenedione and sex steroids in healthy postmenopausal women.
After androstenedione administration, serum
levels of estrone over 12 hours were elevated up to ~115% at the
100 mg dose relative to control. Testosterone levels over 12 hours
were elevated up to ~450% relative to control at the high androstenedione
dose. Estradiol levels were not elevated relative to placebo. The
authors speculate that the elevations in testosterone with androstenedione
administration in these women could have adverse effects (see below).
Study #4 Kicman et. Al. (Clinical Chemistry,
2003; 49:167-169) studied the effect of a single dose of androstenedione
100 mg on plasma testosterone over 24 hours in 10 healthy young
women in a 2-period crossover study.
Plasma testosterone levels integrated over 24 hours were 16-fold
greater than control. The authors also noted that the plasma testosterone
concentrations observed were "similar to those encountered in
abuse of testosterone for anabolic purposes, the peak of the mean
concentrations being at the upper end of the reference interval
for men ." These authors as well express concern about the potential
adverse effects of elevated sex hormone levels in people taking
androstenedione.
Study Conclusion:
"As stated above, if taken in sufficient doses, andro products will
have anabolic effects. Those taking sufficient quantities of these
prohormones to effect anabolism (the goal of the athlete in training)
are by definition at risk for androgenic (anabolic steroids are androgenic,
both effects being mediated through the androgen receptor) as well
as estrogenic effects, all as a result of metabolic conversion of
the precursor hormones to active sex steroids. However, even some
of those not taking sufficient quantities for sufficient durations
to provide obvious performance enhancement or muscle growth may still
be at risk for adverse effects of androgen and/or estrogen excess,
regardless of age or gender."1
