No significant differences were seen in placebo versus DHEA at 150mg in regards to strength gain and lean mass accrual.

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%.
