Androstenedione is the hormone
that is a direct precursor and metabolite of the hormone
testosterone. Androstenedione and testosterone convert back and
forth ( Androstenedione and testosterone) by action of the enzyme
17-beta hydroxysteroid dehydrogenase. Since Androstenedione is
synthesized into testosterone, Androstenedione's supplementation
likely increases testosterone production and the androgenic properties
associated with testosterone that are desired by bodybuilders
such as increased energy, strength, muscle development and decreased
recovery time from workouts. German studies on Androstenedione
have shown up to a 237% increase in free testosterone levels after
a 100 mg dose of Androstenedione . Free testosterone levels may
begin rising in 15 minutes after taking Androstenedione on an
empty stomach.
Androstenedione
This is the biosynthesis pathway
(conversion process) in the production of testosterone:
Cholesterol => Pregnenolone
=> DHEA => Androstenedione => Testosterone
Androstenedione is most likely
better at converting to testosterone than DHEA is. DHEA is two
steps away from testosterone. Androstenedione is only one
step away.
You may also experience increased
energy, heightened sexual arousal, greater sense of overall well-being,
and enhanced recovery and repair after exercise by using Androstenedione
.
Androstenedione
In 100 mg doses, Androstenedione
does not appear to have a negative effect on natural production
of luteinizing hormone (LH). This is important because a reduction
in luteinizing hormone would signal that natural testosterone
production may be diminished. It is unknown whether larger doses
of Androstenedione will affect luteinizing hormone production.

Warning: Everyone - especially
men with prostate problems and women who may have a predisposition
towards breast cancer - should take Androstenedione only under
the care of a doctor. As an androgen, Androstenedione may alter
hormone levels significantly and should be monitored by a doctor.
Women should be careful of Androstenedione and watch for signs
of masculinity, increased facial hair growth and deepening
of the voice.
