4-Androstene-3,6,17-trione (4-AT; also marketed as 6-OXO or 4-etioallocholen-3,6,17-trione) is a drug or nutritional supplement that may increase the testosterone-estrogen ratio, but has no proven effect on body composition. Its use can be detected in urine.
4-AT is a potent irreversible aromatase inhibitor that inhibits estrogen biosynthesis by permanently binding and inactivating aromatase in adipose and peripheral tissue.Aromatase is responsible for the conversion of testosterone to estradiol. Blocking aromatase causes the body to decrease in levels of estradiol, which then results in increase of LH and consequently, testosterone. Since testosterone has myotropic activity and estradiol does not, elevated testosterone levels increase muscle mass. However, there appear to be no human or animal studies testing the hypothesis that 4-AT will produce an anabolic effect.
Androstenedione is further converted to either testosterone or estrogen.
In males, conversion of androstenedione to testosterone requires the enzyme 17β-hydroxysteroid
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.
