6-OXO has been discontinued
You may still be able to find generic 4-Androstene-3,6,17-trione online. A quick look on Amazon reveals a product simply called 3,6,17-Androstenetrione
Background
I am very rarely impressed by the credentials and/or effects of a commercially available supplement. However, 6-OXO is one of those few products that made my list. Not only was I able to find a published study that demonstrated the main chemical is 6-OXO was able to significantly increase the amount of free testosterone and reduce the amount of a certain estrogen in the body, but when I tried it, I actually noticed a significant difference. Though it is marketed as an estrogen reducer, it is actually far more effective as a testosterone booster.
I will explain the chemistry behind the claims later in this article. And the best part is that it contains no synthetic testosterone or testosterone prohormones, so your body doesn’t shut down its own testosterone production (i.e. testicular shrinkage). On the contrary, it actually works to boost your bodies natural production of testosterone! Let’s get into the nuts and bolts to figure out how it works.
The main component of 6-OXO is called 4-Etioallocholen-3,6,17-Trione. This is standard nomenclature for this chemical, but it is also known as 4-Androstene-3,6,17-trione. This chemical is what is known as an aromatase inhibitor. But what does any of this mean?
What is Aromatase?
Aromatase is an enzyme that converts androgens (namely testosterone) into estrogen. 4-Androstene-3,6,17-trione inhibits this enzyme and prevents the conversion of testosterone in to estrogen. By doing this, testosterone levels are raised (because less testosterone is broken down) and estrogen levels are lowered (because less extra testosterone is converted to estrogen). This is the reasons many steroid users turn to 6-OXO during and after cycles. Excess testosterone is normally converted to estrogen and leads to the telltale signs of steroid abuse (breast tissue formation, elevated body fat, etc). By using this compound, the excess testosterone is unable to be converted, and thus does not contribute to these side effects.
