  Testosterone Research: Anabolic Steroids

 

Androstenedione

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.

Androstenedione

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.
