Product Description
4-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 4-Androstenedione via the enzyme 3-β-hydroxysteroid dehydrogenase. The secondary pathway involves conversion of 17-hydroxyprogesterone, most often a precursor to cortisol, to 4-androstenedione directly by way of 17,20-lyase. Thus, 17,20-lyase is required for the synthesis of 4-androstenedione, whether immediately or one step removed.
The production of adrenal 4-Androstenedione is governed by ACTH, whereas production of gonadal 4-Androstenedione is under control by gonadotropins. In premenopausal women, the adrenal glands and ovaries each produce about half of the total 4-androstenedione(about 3 mg/day). After menopause, 4-androstenedione production is about halved, due primarily to the reduction of the steroid secreted by the ovary. Nevertheless, 4-androstenedione is the principal steroid produced by the postmenopausal ovary.
Application
Androstenedione 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.

Usage
Simplified hormone drugs, from the testis or urine extracted with the role of a male hormone steroids, norethisterone, testosterone propionate in the middle Body, is widely used in small rheumatoid arthritis, diuretic, and a variety of contraceptive to control infectious inflammation.

In males, conversion of androstenedione to testosterone requires the enzyme 17β-hydroxysteroid dehydrogenase.
In females, androstenedione is released into the blood by theca cells. Conversion of androstenedione to estrogen (e.g., estrone and estradiol) requires the enzyme aromatase. Androstenedione is a substrate for estrogen production in granulosa cells which produce aromatase. Thus, theca cells and granulosa cells work together to form estrogens.

Effect
Because androstenedione can be converted to estrogenic steroids, people taking this supplement may have estrogenic side-effects.
4-Androstenedione has been shown to increase serum testosterone levels over an eight-hour period in men when taken as a single oral dose of 300 mg per day, but a dose of 100 mg had no significant effect on serum testosterone. However, serum levels of estradiol increased following both the 100 mg and 300 mg doses. The study also reported that the serum level of estrogens and testosterone produced varied widely between individuals.
In child development, higher levels of androstenedione in boys have been associated with higher levels of acting out behaviors.
Dosage
Dietary supplement dosages of androstenedione range from 5 to over 50mg per day in the morning or 60 minutes before working out. Experts suggest the best way to take andro is by cycling it. The proper cycle is six weeks of taking it followed by two weeks off.
