11-OXO – Product Information

Adrenosterone, also known as 11 OXO, is an endogenous hormonal compound that is being investigated as a potential dietary supplement that may be capable of increasing fat loss and muscle mass. 11 OXO has shown the potential to convert into 11-ketotestosterone, which contributes to adrenosterone’s possible androgenic effects.

It is proposed that adrenosterone may function as an inhibitor of the 11beta-hydroxysteroid dehydrogenase type 1 enzyme (11beta-HSD1), which is primarily responsible for the potential reactivation of cortisol from cortisone. Cortisol is a catabolic hormone that may inhibit muscle growth, and as such by suppressing or inhibiting cortisol levels, 11 OXO may potentially promote muscle growth.

CAS Number 739-27-5
Molar Mass 302.4g·mol−1
Chemical Formula C19H26O3
IUPAC Name (6aR,10aR)-1-hydroxy-6,6-dimethyl-3-pentyl-6a,7,10,10a-tetrahydrobenzo[c]chromene-9-carbaldehyde

What is 11-OXO?

Adrenosterone, also known as 11-OXO, is a prohormone made by the adrenal glands.

As mentioned above, prohormone 11 OXO converts to 11-ketotestosterone, a hormone that is highly fascinating for its androgenic potential.  A non-aromatizing counterpart of testosterone, research shows it may increase sex desire while also causing dry lean gains and fat reduction. [R]

Humans’ conversion of 11 OXO to 11-ketotestosterone is a major factor in the substance’s observable potential androgenic effect.

The true name of this hormone is androst-4-ene-3,11,17-trione, although, it is mostly referred to it as 11 oxo. 11-Keto-androstenedione and 11-Keto-androstenetrione are trademark names for this hormone.

How does 11-OXO work?

11 OXO works in two ways. It is a prohormone for 11-ketotesterone, a non-aromatizing testosterone analog. Many of the potential advantages of testosterone, such as enhanced libido and muscle growth, are also potentially shared by 11 OXO.

The 11beta-hydroxysteroid dehydrogenase type 1 reductase (11HSD1R), an enzyme that converts cortisone to cortisol in target tissues such as fat, liver, and muscle, is another way that 11-OXO operates. 11-OXO simply takes up residence in the enzyme, denying cortisone access. Competitive inhibition is the  more general term for this. Cortisone won’t have the chance to be converted to cortisol at the target tissue if it can’t access 11HSD1R.

The potential beneficial aspect of 11 OXO is that it only affects the 11HSD1R enzyme. As a result, 11-OXO provides a way to manage cortisol’s potentially harmful effects on the body without interfering with cortisol’s essential life-sustaining tasks. [R]

11-OXO Research

Multiple studies have been carried out on 11 OXO. However, the available clinical data isn’t sufficient to claim it is safe for human consumption. Purerawz sells 11 OXO for research purposes only.

11-OXO and Fat Loss

Since 2007, supplements containing adrenaline have been offered for sale as potential weight-loss and muscle-building aids. It is believed to be a selective competitive 11-HSD1 inhibitor, which is what causes cortisol to be activated from cortisone. hence halting muscle deterioration and causing the majority of its effects. [R]

This has given credence to the belief that potential future research of 11 OXO, an 11-HSD1 inhibitor, in lean mass cycles may be very promising as researchers continue to look for safer and improved methods that will allow body composition great increases in strength alongside fat loss.

11-OXO and Metabolic Syndrome

The main enzyme in charge of controlling intracellular cortisol levels is 11-hydroxysteroid dehydrogenase type 1 (11-HSD1). An appealing method for treating obesity and other symptoms of metabolic syndrome is the inhibition of 11-HSD1. As mentioned above, 11-OXO is believed to be a potent 11-HSD1 inhibitor. [R]

11-OXO and Lean Mass

A recent research study showed that patients using an 11-HSD1 inhibitor had higher amounts of androgens in their blood, which were favorably linked with changes in their overall lean muscle mass. This shows the potential of 11-OXO as an 11-HSD1 inhibitor to potentially promote building lean mass and notice the improved fat loss. [R]

11-OXO and Cancer

Research shows that Adrenosterone shows the potential to act as a suppressor of the metastatic progression of human cancer cells. [R]

11-OXO Potential in Emerging Medical Fields

Potential involvement in the therapy of additional unmet medical needs, such as Alzheimer’s disease, vascular inflammation, cardiovascular disease, and glaucoma, is further supported by recent evidence. [R]


Is 11-OXO a Conventional Anabolic Compound?

11-OXO, sometimes referred to as (Adrenosterone), is a well-known non-methylated designer steroid/pro-hormone that was first released by Ergopharm and has subsequently been copied by a number of other companies.

What do researchers stack 11-OXO with?

Researchers will generally stack 11-OXO with some of the following:


11-OXO has shown massive potential as a potent prohormone and 11-HSD1 inhibitor specifically as it relates to the potential to add lean mass and aid overall body composition. PureRawz sells 11-OXO for research purposes only.
