androstadienedione is used for simplified hormone drugs,from the testis or urine extracted with the role of a male hormone steroid,norethisterone,testosterone propionate in the middle body,is widely used in small rheumatoid arthritis,diuretic,and a variety of contraceptive to control infectious inflammation.
androstadienedione is the precursor to bolde-none, and as of january 4,2010 is a schedule iii controlled substance.in 2004 the united states congress passed the anabolic steroid control act of 2005 which placed 36 steroids and over the counter pro-hormones into schedule iii of the controlled substances act.
