11-OXO is the trademark name for adrenosterone.  Adrenosterone is an adrenal androgen.  “Adrenal androgen” means it is a hormone produced by the adrenal gland that is in the same general hormonal class as testosterone (another example of an adrenal androgen is DHEA). 

Adrenosterone is released by the adrenal gland in conjunction with other stress hormones, primarily cortisol and cortisone.  The exact function of adrenosterone has never been fully understood, however recent research seems to indicate that it serves to modulate the actions of cortisol in the body.

Cortisol is a vital hormone made by the adrenal gland and it is considered a stress hormone.  When your body is stressed it seeks to quickly liberate energy stores and cortisol assists this by stimulating the breakdown of muscle protein to amino acids and stored triglycerides (fat) to free fatty acids.  It also instructs the liver to up-regulate its systems for processing these fuels - the gluconeogenesis pathway for amino acids and the beta-oxidation pathway for fats. Because visceral fat is the closest fat to the liver it is used for energy first and therefore is reduced by the use of 11 OXO. Because of this, 11 OXO is a perfect ingredient for any weight loss or anti-aging product.

It also is known that a functional level of androgenic hormones in females promotes sexual health and activity, feelings of well being, maximizes muscle mass and function, and inhibits bone loss. Further, a functional level of androgenic hormones may promote cardiovascular and coronary health, decrease breast tenderness, decrease vasomotor instability, modulate immune function, enhance certain cognitive abilities, improve urogential health, reduce estrogen supplementation related side effects, and provide direct neuroprotective effects. Based on these principles, it is believed the 11 OXO would also make a great women’s libido enhancer.
