4-Androstenedione Descriptions:

Androstenedione is a steroid hormone which is used for pharmaceutical, and is the common precursor of male and female sex hormones. Some androstenedione is also secreted into the plasma, and may be converted in peripheral tissues to testosterone and estrogens.
Androstenedione can be synthesized in one of two ways. The primary pathway involves conversion of 17-hydroxypregnenolone to dehydroepiandrosterone by way of 17,20-lyase, with subsequent conversion of dehydroepiandrosterone to androstenedione via the enzyme 3-hydroxysteroid dehydrogenase. The secondary pathway involves conversion of 17-hydroxyprogesterone, most often a precursor to cortisol, to androstenedione directly by way of 17,20-lyase. Thus, 17,20-lyase is required for the synthesis of androstenedione, whether immediately or one step removed.
The production of adrenal androstenedione is governed by ACTH, whereas production of gonadal androstenedione is under control by gonadotropins. In premenopausal women, the adrenal glands and ovaries each produce about half of the total androstenedione(about 3 mg/day). After menopause,androstenedione production is about halved, due primarily to the reduction of the steroid secreted by the ovary. Nevertheless, androstenedione is the principal steroid produced by the postmenopausal ovary.

4-Androstenedione Effects:

Androstenedione is an androgenic hormone produced naturally in men and women that's converted by the liver into testosterone. It's produced in the adrenal glands and gonads by DHEA (dehydroepiandrosterone) or 17-a-hydroxyprogesterone for those technical gurus. In essence, androstenedione is a mere single step away (that is, one metabolic reaction in the body) from testosterone.
So from this, the assumption has been made that when androstenedione is ingested, it readily converts to testosterone, and when combined with physical exercise, the direct result is muscular growth. But, it's not that simple. You see, androstenedione's effects on human muscle growth are still "up in the air" in the scientific community since no studies to date have revealed direct positive effects. Although there does appear to be a definite surge of testosterone in the blood when androstenedione is supplemented before a workout, which may lead to more "aggressive" weight-training sessions, potentially resulting in increased muscle growth.
The theory was that if additional androstenedione were introduced, the body would treat it like it occurs naturally. This leads to abnormally high testosterone levels because the ingested andro serves as a manufactured, inactive precursor to testosterone. Males produce testosterone—an anabolic sex hormone—in large quantities. The resulting spike in testosterone upon its direct conversion from andro should enhance the adaptations of resistance and strength training athletes.
