Testosterone is extremely important to the human body — especially for men. It’s the primary androgenic hormone and is necessary to maintain your overall health and well-being. It plays a vital role in developing male reproductive tissues, and helps maintain muscle mass and sexual desire. When the body fails to produce normal levels of testosterone, a condition called Hypogonadism or Low T occurs. This can result in feeling fatigued, gaining weight, and experiencing other issues including erectile problems, osteoporosis and depression.
