Most men do not have optimal testosterone levels. If your levels are ‘normal’, then you may not be in the optimal range that is best for you. “Optimal Testosterone Levels” mean that you feel like the best version of yourself – you have the energy to perform daily activities and workouts, you build muscle easily, and you have a healthy sex drive. No two men will experience the exact same symptoms even if they are at the same level. If your testosterone is below your optimal level, then you can experience fatigue, decreased sex drive or performance, increased body fat or weight, loss of bone & muscle mass, and moodiness or irritability. Not only do these symptoms affect how you feel, but other health issues may arise such as osteoporosis or depression.
