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-Androstene-3,6,17-trione 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-Androstene-3,6,17-trione will produce an anabolic






4-Androstene-3,6,17-trione refer to the same chemical compound that is a steroidal testosterone


booster/anti-aromatase agent. First identified in cow adrenal glands it was further found to be a


natural metabolite of androstenedione metabolism in humans and most mammals. This makes 4-


Androstene-3,6,17-trione a perfectly legal dietary supplement under the current DSHEA law and


since it is not androgenic, not at all an anabolic steroid. What 4-Androstene-3,6,17-trione does is


reduce an enzyme in the body that turns your testosterone into estrogen. By blocking this enzyme


two major things happen, first it causes you to keep more of your testosterone and second, the


body senses a lack of estrogen and causes the testes to release more testosterone.

4-Androstene-3,6,17-trione has been well studied in men and the original manufacturer of 4-


Androstene-3,6,17-trione, Ergopharm Inc actually paid for quite a few studies in both men and


rats. The most telling one was done by Incledon, which studied 4-Androstene-3,6,17-trione in


doses of 300mg in healthy men, then measured the effects. The Incledon study found a boost of


testosterone of about 200% with a slight reduction in estradiol, which means it was very effective


at boosting testosterone while reducing estrogen. This was the first really well tested testosterone


booster on the market.
