The FDA announced Tuesday that it is increasing warnings against testosterone and other steroids, NBC News reported.
In addition to existing concerns about personality changes and other health issues, the drugs can be easily abused, according to the FDA.
"Reported serious adverse outcomes include heart attack, heart failure, stroke, depression, hostility, aggression, liver toxicity and male infertility," the FDA said in a statement. "Individuals abusing high doses of testosterone have also reported withdrawal symptoms, such as depression, fatigue, irritability, loss of appetite, decreased libido and insomnia."
Testosterone, which is used to fight the effects of aging, has been heavily criticized by the FDA. It is currently a $2 billion industry with men purchasing gels, pills and injections.
