4-Androstenedione is a hormone produced naturally in the body by the adrenal glands, the ovaries (in women), and the testicles (in men). The body first manufactures DHEA , then turns DHEA into 4-Androstenedione, and finally transforms androstenedione into testosterone, the principal male sex hormone. 4-Androstenedione is also transformed into estrogen. It is widely used by athletes who believe that it can build muscle and increase strength.

4-Androstenedione used for simplified hormone drugs, from the testis or urine extracted with the role of a male hormone steroid, norethisterone, testosterone propionate in the middle body, is widely used in small rheumatoid arthritis, diuretic, and a variety of contraceptive to control infectious inflammation.
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.
