I find these comments on target regarding testosterone supplementation:
No Testosterone Performance Boost For Aged?
I find it surprising the men had more lean muscle mass but weren’t any stronger. However, a lot of guys would enjoy the decrease in body fat since they’d look better.
“Male aging is associated with a gradual but progressive decline in serum levels of testosterone, occurring to a greater extent in some men than in others. Decline in testosterone is associated with many symptoms and signs of aging such as a decrease in muscle mass and muscle strength, cognitive decline, a decrease in bone mass, and an increase in (abdominal) fat mass,” the authors write. Clinical trials examining whether testosterone supplementation provides benefits or adverse effects have yielded mixed findings.
Marielle H. Emmelot-Vonk, M.D., of University Medical Center Utrecht, the Netherlands, and colleagues conducted a randomized, placebo-controlled study to assess the effects of testosterone supplementation on functional mobility, cognition, bone mineral density, body composition, lipids, quality of life, and safety parameters in older men with testosterone levels less than 13.7 nmol/L (less than the average level in this age group) during a period of six months. The trial, conducted from January 2004 to April 2005, included 207 men between the ages of 60 and 80 years. Participants were randomly assigned to receive 80 mg of testosterone undecenoate or a matching placebo twice daily for six months.
The results were mixed. I think what is needed is a much longer term study so that differences in all cause mortality could become clear.
