it is a steroid hormone produced in the adrenal glands and the gonads as an intermediate step in the biochemical pathway. Androstenedione is the common precursor of male and female sex hormones. Androstenedione is further converted to either testosterone or estrogen. Levels are normally 30-200 ng/dL (1.0-7.0 nmol/l) in females and 40-150 ng/dL (1.4-5.2 nmol/l) in males
As a supplement, it is used to increase the production of the hormone testosterone to enhance athletic performance, increase energy, keep red blood cells healthy, enhance recovery and growth from exercise and increase sexual desire and performance.
