High testosterone levels could indicate a tumor in your adrenal glands or testicles. "Normal" ranges for testosterone also vary significantly based on your age and sex. Laboratories may have different reference ranges for normal testosterone levels.
Nitrogen is a vital component of amino acids, the building blocks of proteins. If you’re experiencing challenges with your nutrition or hormonal health, consider scheduling a complementary discovery call with one of our men’s health nutritionists. For further reading, check out our previous post on why undereating can cause a drop in testosterone. By focusing on testosterone-friendly foods, resistance training, and recovery strategies, you can sustain peak performance for life. Lifting heavy weights, especially compound movements, stimulates testosterone production. Low-carb diets can suppress testosterone, so athletes need quality carbs for performance.
However, many men with normal testosterone levels have similar symptoms, so a direct connection between testosterone levels and symptoms is not always clear. For example, a man with osteoporosis and low testosterone can increase bone strength and reduce his fracture risk with testosterone replacement. Also, as men get older, their livers make more sex hormone binding globulin (SHBG), which binds to testosterone circulating in the bloodstream. In fact, as men age, testosterone levels drop very gradually, about 1% to 2% each year — unlike the relatively rapid drop in estrogen that causes menopause. Agnathans (jawless vertebrates) such as lampreys do not produce testosterone but instead use androstenedione as a male sex hormone. When testosterone levels are low, gonadotropin-releasing hormone (GnRH) is released by the hypothalamus, which in turn stimulates the pituitary gland to release FSH and LH. Specific proteins include sex hormone-binding globulin (SHBG), which binds testosterone, dihydrotestosterone, estradiol, and other sex steroids.
Consuming healthy fats may also help support testosterone levels and hormone balance. Eating enough protein can help you maintain healthy testosterone levels and can aid in fat loss, which may be beneficial, too. Interestingly, testosterone also plays an important role in female health and sexual well-being. For males who have gone through puberty, the test is mostly used for symptoms of low T levels (testosterone levels which are too low).
Achieving these levels naturally through strength training, quality sleep, and a balanced diet is the safest and most effective approach. However, TRT should only be pursued under professional guidance, as misuse can lead to hormonal imbalances, cardiovascular risks, and other health issues. Adequate sleep (7–9 hours per night) is also essential, as testosterone secretion peaks during deep sleep stages. Regular strength training, particularly compound exercises like squats, deadlifts, and bench presses, has been shown to naturally boost testosterone production. However, the relationship between testosterone and muscle gain is not linear; there is an optimal range within which the benefits are maximized. For example, it can decrease the production of cortisol, a catabolic hormone that breaks down muscle tissue. Testosterone also indirectly supports muscle growth by improving recovery and reducing fatigue.
