When a diagnosis of testosterone deficiency has been made your Doctor may decide to initiate testosterone replacement therapy. Testosterone replacement therapy is carried out by applying a testosterone containing gel onto the skin or by administering a testosterone injection. Studies have found that testosterone replacement therapy restores testosterone to normal body levels and leads to an improvement in sexual interest, body and muscle mass, bone density, mood and energy levels¹.
