Androstenedione (Andro), pronounced andro-steen-dee-own, is a direct precursor
to the hormone testosterone. It was the first prohormone to really break into
the sports nutrition industry.
Although andro was discovered in 1935, it wasn�t until scientists learned that
it became testosterone in the body in the 1950�s that it was seriously considered.
Androstenedione is naturally produced in men and women, and is found in Scotch
pine trees. What? Scotch pine trees? Yes, and this simple fact classifies it
as a dietary supplement.
2. What does it do and what scientific studies give evidence to support this?
Andro, much like DHEA, can have powerful effects on muscle-building and athletic
performance. DHEA is two steps away from becoming testosterone. However, unlike
DHEA, andro is only one step away from testosterone. Therefore, by itself, it
is not a muscle builder; but after the liver converts it to testosterone-watch
out, BIG gains are on their way. Studies conducted on andro indicate that when
taken orally, androstenedione produces significantly more testosterone than
either a placebo or DHEA. In fact, East German athletes have used andro to improve
their athletic performance in the Olympics since 1980. According to German records,
their athletes experienced raises in testosterone levels as significant as 140%
to 183% of normal with 50 mg of andro and incredibly 211% to 237% of normal
with 100 mg of andro! These testosterone boosts have lead many athletes to improving
their performance and lean muscle mass. This has lead many to believe that it
may even work well as a libido booster.
3. Who needs it and what are some symptoms of deficiency?
Those who would benefit most from androstenedione supplementation are those
who are into bodybuilding, weight training, and demanding sports. Due to its
incredible testosterone producing effects (only one step away), andro has emerged
as an important almost magical supplement. Since androstenedione is not an essential
nutrient, it is not associated with deficiency.
4. How much should be taken? Are there any side effects?
Most experts recommend supplementing with andro in doses between 50 to 100
mg in the morning or 60 minutes before working out, since that�s when testosterone
levels peak. Experts suggest the best way to take andro is by cycling it. The
proper cycle is six weeks of taking it followed by two weeks off. Some small
side effects are acne, a decrease in HDL (the good cholesterol), and prostate
hypertrophy. It is not recommended for women, as it could lead to a lower voice,
facial hair, and acne. Also, anyone with heart problems should consult a doctor
before supplementing with androstenedione. Andro is very safe. It is not a drug
like anabolic steroids (the illegal ones), therefore it doesn�t pose a threat
as a liver or kidney toxifier.
