Are you a doctor ?
Your post is more untrue than mine is. Unless you actually have websites to back up what you say ?
"As men age, their testosterone levels gradually decline. After 30 years of age, levels decrease by about 1.5 percent per year. Low testosterone levels can result in decreased muscle mass and bone density, insulin resistance and low sex drive, as well as less energy, more irritability and feelings of depression, the researchers noted."
