Relationship between Low Levels of Anabolic Hormones and Mortality in Older Men

The anabolic hormones testosterone, IGF-1 and DHEA (a pre-hormone) are receiving more and more attention by health professionals because the anabolic-catabolic imbalance that favors catabolism is a key factor in accelerated physical deterioration aging.[1, 2] Anabolic impairment can speed up the age-related decline in muscle mass and physical performance, increase in fat mass, development of insulin resistance, cardiovascular risk factors, metabolic syndrome and diabetes, conditions that in turn affect mortality.[3-18]

Interestingly, low levels of multiple anabolic hormones, rather than a single one, has a stronger association with age related muscle loss and the frailty syndrome. [19, 20] In men with chronic heart failure, deficiency of more than one anabolic hormone identifies patients with higher mortality rates.[21]

An interesting study sought to investigate the relationship between parallel deficiency of several anabolic hormones and mortality in a general population of older men, regardless of coexisting disease:[22]

Combined Testosterone and GH therapy for best results on body composition and safety profiles

Prevention of age-related muscle loss (sarcopenia)

Many studies have highlighted the importance of investigating all major hormones, and correcting deficiencies and imbalances if present.[1-8] Given the known mechanisms of testosterone and GH/IGF-1 in building muscle (and possibly also DHEA in elderly) it is reasonable that age-related low levels of anabolic hormones contribute over time to sarcopenia and frailty.[1, 2, 4, 7, 9, 10]

Thus, multiple small effects in aggregate can lead to adverse loss of muscle and disability. In this scenario, if replacement was to occur, it would require lower doses of multiple anabolic hormones. An added benefit to this approach would be fewer side effects from the use of lower hormone doses [11]. In addition, multiple anabolic hormone replacement might also have beneficial additive or even synergistic effects.[11-13]

A notable study investigated whether supplementation with testosterone and GH together, in physiological doses, results in greater improvements in body composition and muscle performance in older men, compared to testosterone supplementation alone...
