50mg of DHEA given daily for 6 months to older frail women*was unable to significantly affect bone mineral density over 6 months yet increased serum steroid status (testosterone, estrogen, DHEA) and increased lower body strength and functionality when DHEA was used in conjunction with non-strenuous exercises.

DHEA, either alone at 50mg daily or in combination with an aromatase inhibitor (atamestane at 100mg) was studied for 36 weeks in otherwise healthy an non-hospitalized older men with low scores on physical strength (frailty).
Testosterone increased in all groups, with the DHEA+AI group increasing more than double that of DHEA or AI alone (8.5, 3.5, 4.9nmol/L respectively), DHEA+AI had about 1.3rd the increase in estrogen seen in DHEA, while AI saw a decrease relative to placebo. IGF-1 increased in all groups, but only significantly in the combination. The combination seemed to improve body composition, but was statistically insignificant.
Cognitive decline was measured via MMSE but showed no influence with DHEA, and the changes in IGF binding proteins were too variable to be significant (although an interaction seemed to be present)

DHEA at 50mg daily in menopausal women does not influence muscle mass, libido, sleep quality or well being despite increasing circulating androgen status. Estrone and SHBG were unaffected alongside cortisol. Functional tests failed to show a protective effect of either DHEA or estrogen replacement therapy (active control) and power output (knee flexion) was unaffected. Cholesterol decreased 8%.
