bolandione and its Impurities

Bolandione, also known as 19-norandrostenedione, as well as 19-norandrost-4-en-3,17-dione or estr-4-ene-3,17-dione, is a precursor of the anabolic-androgenic steroid. Scientific studies have shown that oral administration of bolandione is "a very ineffective strategy for stimulating skeletal muscle mass increases but may be associated with side effects"..
