This makes 6 OXO a perfectly legal dietary supplement under the current DSHEA law and since it is not androgenic, not at all an anabolic steroid. Sadly, like most hormonal items, professional sports was to be the ultimate downfall for this wonder supplement. 6 OXO was once the most potent testosterone booster on the market and it was a pioneer for its time.

What 6 OXO does is reduce an enzyme in the body that turns your testosterone into estrogen. 6 OXO (R) is no longer on the market and sadly the day of steroidal anti estrogens is setting into the sunset, luckily there is a new generation of plant based testosterone boosters that rival these strong products and give even 6 OXO a run for its money. 6 OXO has many names on the market, 6 keto androstenedione, Androstene3,6,17 trione, 4 Androstene 3,6,17 trione, 4 AT and a even 4 etioallocholen 3,6, 17 trione. All of these 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.
