Testosterone is the quintessential “male” hormone. Its androgenic properties give men confidence, drive, and determination to seize each and every day. Naturally, testosterone serves a purpose in almost every aspect of a man’s life, whether it’s with regards to relationships, career goals, athletic performance, socializing, or sex. Until about age 25, the male body usually synthesizes a sufficient amount of testosterone. However, once a man ages past this point, the body no longer produces as much testosterone; in fact, it typically produces only a fraction of what it used to at younger ages. When natural testosterone production drops significantly, symptoms of low T are likely to manifest. These symptoms often include chronic fatigue, difficulty focusing, inability to achieve an erection, insomnia, reductions in strength and muscle mass, and others. Fortunately, the symptoms of low T are almost always corrected after reestablishing and maintaining healthy testosterone levels (which is the objective of TRT).
