Androstene is the hormone that
is a direct precursor and metabolite of the hormone testosterone.
Androstene and testosterone convert back and forth ( Androstene
and testosterone) by action of the enzyme 17-beta hydroxysteroid
dehydrogenase. Since Androstene is synthesized into testosterone,
Androstene'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 Androstene have shown up to a 237% increase
in free testosterone levels after a 100 mg dose of Androstene
. Free testosterone levels may begin rising in 15 minutes after
taking Androstene on an empty stomach.
This is the biosynthesis pathway
(conversion process) in the production of testosterone:
Cholesterol => Pregnenolone
=> DHEA => Androstene => Testosterone
Androstene is most likely better
at converting to testosterone than DHEA is. DHEA is two steps
away from testosterone. Androstene 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 Androstene
In 100 mg doses, Androstene 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 Androstene will affect luteinizing hormone production.
Warning: Everyone - especially
men with prostate problems and women who may have a predisposition
towards breast cancer - should take Androstene only under the
care of a doctor. As an androgen, Androstene may alter hormone
levels significantly and should be monitored by a doctor. Women
should be careful of Androstene and watch for signs of masculinity,
increased facial hair growth and deepening of the voice.
