Androstenedione

is a steroidic

hormone with a cyclic structure.

Androstenedione acts like a steroid once it is metabolized by the body and can pose similar kinds of health risks. People produce androstenedione naturally during the making of testosterone and estrogen.

Supplementation with androstenedione increases blood levels of testosterone, which among other things, will lead to an increase in strength and muscle mass.

No.

Androstenedione is a dietary supplement promoted to increase levels of the hormone testosterone. The FDA no longer allows androstenedione to be marketed as a dietary supplement in the United States due to safety issues, and it is banned from use at most amateur and professional athletic events.
