What is 4-Androstenedione?

Androstenedione Application
Basically pregnenolone, the grandmother of all steroid hormones, is converted into DHEA, which in turn is converted into androstenedione, which can then be converted into testosterone and estrogens. Hence, androstenedione side effects are likely to be similar to the side effects of DHEA, testostérone, or other androgens, and perhaps partially similar to estrogen side effects.
Some body builders report anecdotally that they notice increased strength on the days they work out when they use it. Others use it occasionally to boost sex drive or wellbeing. Those who are young and already have high levels of testosterone or androstenedione in their system are not likely to notice much of a sex boosting effect. Middle aged and older individuals may notice the benefits more easily. It is potentially an alternative to DHEA or testosterone as a form of androgen replacement in aging men or women.
A highly publicized study indicates that androstenedione may not live up to its hype. The study published in the June 2, 1999 issue of the Journal of the American Medical Association compared 300 mg with a dummy pill in 20 men ages 19 à 29 during an eight-week weightlifting program. Researchers found no difference in strength between the two groups of men.
