What are some of the main medical treatments for sarcopenia?

No specific drugs have been approved for the treatment of sarcopenia. Testosterone treatment may increase muscle mass and strength in older men with low serum testosterone levels (<200–300 ng/mL) and muscle weakness.^[1] In addition, preliminary evidence suggests that myostatin inhibitors, which block the actions of myostatin — a protein secreted by muscle cells that inhibits protein synthesis and hypertrophy — may increase muscle mass and some measures of physical performance.^[2][3] However, the medical use of myostatin inhibitors as a treatment of sarcopenia is currently limited to clinical trials.
