Articles by Patrick Arnold

Patrick Arnold, widely considered the "father of prohormones", is an organic chemist known for introducing androstenedione, 1-androstenediol, and methylhexanamine into the dietary supplement market. He became infamous for creating the designer steroid tetrahydrogestrinone, also known as THG and "the clear".

Arnold manufactured THG, norbolethone and desoxymethyltestosterone (DMT) for athletes in the BALCO doping scandal. The designer steroids, which were legal at the time of their creation, were difficult for anti-doping authorities to detect.
