Daily administration of the selective androgen receptor modulator GTx-024 (enobosarm) at 3 mg significantly increases total lean body mass and improves physical function in healthy elderly men and postmenopausal women without causing adverse androgenic side effects.

For healthy older adults looking to build muscle, a daily 3mg dose of the SARM GTx-024 (enobosarm) taken for 12 weeks significantly increases lean body mass and physical function without the typical side effects of testosterone therapy. This intervention works best when combined with maintaining your current diet and exercise habits, as the drug itself drives the anabolic response.

GoodSupportsHIGH confidence
GTx-024 treatment resulted in dose-dependent increases in total lean body mass that were statistically significant (P<0.001, 3 mg vs. placebo) and clinically meaningful. There were also significant improvements in physical function (P=0.013, 3 mg vs. placebo)... GTx-024 showed a dose-dependent improvement in total lean body mass and physical function and was well tolerated.
