6 OXO was once the most potent testosterone booster on the market and it was a pioneer for its time. All of these refer to the same chemical compound that is a steroidal testosterone booster/anti aromatase agent. Sadly, like most hormonal items, professional sports was to be the ultimate downfall for this wonder supplement. 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. 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. 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 6 OXO a perfectly legal dietary supplement under the current DSHEA law and since it is not androgenic, not at all an anabolic steroid.
