A long-term retrospective study examined the effects of testosterone and/or GH supplementation on body composition and quality of life (QoL).Methods: A database survey assessed the records of 91 men and 97 women (ages 25–82) in treatment groups based on their hormonal status: dehydroepiandrosterone but no hormonal supplementation (control); testosterone only (Tes); GH only (GH); and testosterone plus GH (Tes+GH). Pre- and post-treatment assessments recorded changes in fat and lean mass, BMD, and QoL.Results: After an average of 3 years of treatment, weight decreased in women in the control and Tes+GH groups but remained stable in men in all groups. Tes and Tes+GH produced statistically significant increases in lean mass, reductions in fat mass, and improvements in BMD in both sexes; GH produced similar changes in women. QoL and mood improved in all groups. Treatments were generally safe and well tolerated.Conclusions: In this retrospective survey, treatment with testosterone and/or GH was associated with favorable effects in men and women across a wide age range.Keywords: testosterone, growth hormone, body composition, quality of life
