Probably one of the most masculine hormones - testosterone responsible for maintenance of muscle mass, bone density, and last but not least important - sex drive. Testosterone production is at its peak in early adulthood and drops a little bit each year thereafter. There are some certain conditions when body doesn’t produce, or stops producing the right amount of testosterone: hypogonadism also called called “low T” and/or sarcopenia the muscle mass loss in elderly individuals. The ones diagnosed with hypogonadism and/or sarcopenia can try testosterone testosterone supplements.
