Key Points for Practice

• Exercise, weight loss, and better sleep will improve symptoms of hypogonadism in people with testosterone levels as low as 264 ng per mL.

• Growth hormone supplementation does not improve physical or cognitive performance in athletes or older adults.

• Thyroid supplementation for euthyroidism does not improve muscular, psychologic, or cognitive function and does not reduce weight in obesity.

• Adrenal fatigue is not a recognized condition and treatment does not improve symptoms. Supplements labeled for adrenal support often contain thyroid and steroid hormones, even when labeled hormone free.

From the AFP Editors

Off-label use of hormone medications and use of hormone supplements have increased dramatically over the past 20 years. Common nonspecific symptoms such as fatigue, low energy, poor sleep, weight gain, and lower libido are often assumed to be caused by hormone deficiencies, leading to treatment without an identified deficiency. An example is the concept of adrenal fatigue, a proposed condition that cannot be directly assessed. The risks of using hormone supplements can be substantial, and these supplements do not have demonstrated offsetting benefits. The American Association of Clinical Endocrinologists (AACE) and the American College of Endocrinology (ACE) developed a summary of known risks of using off-label hormone treatments.

Testosterone and Androgens

Although androgens such as testosterone are one treatment for male hypogonadism, most men receiving treatment do not meet diagnostic criteria for hypogonadism. Only one in 10 patients with a testosterone prescription had testosterone levels measured within six months. Studies suggest that testosterone levels as low as 264 ng per mL (9.16 nmol per L) are normal, and many patients with borderline levels can be treated with exercise, weight loss, and improved sleep. Although testosterone levels decline with obesity, hypertension, hyperlipidemia, type 2 diabetes mellitus, and obstructive sleep apnea, the U.S. Food and Drug Administration has concluded that effectiveness and safety of testosterone replacement have not been established for these patients.

Testosterone is the most common anabolic steroid used by bodybuilders and athletes. In younger people, exogenous androgens can reduce fertility, causing decreased spermatogenesis, and can lead to acne and polycythemia (Table 1).

The safety of testosterone therapy has not been evaluated in large, long-term trials. Its effect on cardiovascular events is uncertain, and it can increase progression of metastatic prostate cancer.

Growth Hormone

Similar to androgens, growth hormone is commonly used by athletes to enhance performance and is prescribed to older adults to combat the effects of aging. In athletes, limited data suggest that growth hormone slightly increases lean body mass and decreases fat mass without improving strength or performance. Results are similar in older adults, with body composition improvements but no change in functional capacity, strength, or on other effects of aging.

In clinical trials, nearly one-half of healthy adults have adverse effects from growth hormone supplementation, including arthralgias,
