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...

DHEA - does it have any beneficial non-hormonal effects?

DHEA (dehydroepiandrosterone) is most known for being a pro-hormone which in the body gets converted to testosterone and estrogen. It is a long held view that DHEA exerts all its effects via conversion to testosterone and estrogen. However, recent studies show that DHEA also has several health promoting non-hormonal actions...

DHEA 101

DHEA is produced mainly by the adrenal cortex, and is rapidly sulfated by sulfotransferases into DHEA-S. DHEA and its sulfated form DHEA-S is the most abundant steroid (pro)hormone circulating in the blood stream.[1] The sulfated from of DHEA has a longer half-life in the blood and its levels remain stable throughout the day, are not altered significantly by the menstrual cycle. When getting a blood test for DHEA, the fraction that is routinely measured is therefore DHEA-S. In response to metabolic demand, DHEA-S is rapidly converted back to DHEA (e.g. is  hydrolyzed to DHEA by sulfatases).

DHEA levels decrease approximately 80% between ages 25 and 75 year.[2, 3] This large decline in DHEA spurred research interest in the possibility that aging related DHEA deficiency may play a role in the deterioration of physiological and metabolic functions with aging, and in the development of chronic diseases.
