Gene doping - four of the obvious methods

Gene doping involves inserting genes into an athlete's cells that stimulate the production of certain genes which are thought to enhance performance. Here are four of the obvious methods.

Myostatin blocking

Myostatin is the body's way of regulating and controlling muscle growth. A gene that blocks the production of myostatin would encourage muscles to grow. But while the muscles might bulge, the skeleton and organs do not grow in sync.

GROWTH HORMONE THERAPY

Inserting genes that produce growth hormones would also help an athlete develop strength and speed. But again, the rest of the body does not grow in tandem.

Erythropoietin (EPO) therapy
