E-XSTANE contains a powerful metabolite of 7-Keto DHEA known as Androsta-3,5-diene-7,17-dione, which acts as a suicidal inhibitor of the aromatase enzyme, preventing the conversion of testosterone to estrogen. This compound may also lower systemic cortisol levels while at the same time increase Luteinizing Hormone. In turn this may increase the body’s natural testosterone production while lowering/preventing any increases in estrogen.

The reduction in cortisol is especially important for athletes due to the stress-inducing effects of intense training. Elevated levels of cortisol, the stress hormone, can lead to a catabolic effect on muscle and increased fat storage.
