HealthDay News — The US Food and Drug Administration warns that supplemental testosterone and related anabolic-androgenic steroids (AAS) can result in heart attacks, personality changes and infertility. Since they are easily abused, the addition of labeling on all prescription testosterone products will be revised.

Millions of American men currently use testosterone pills, gels or injections in hopes of boosting their physical health or libido. AAS are legally prescribed to treat conditions such as delayed puberty and diseases that cause muscle loss, such as cancer or AIDS.

“Abuse of testosterone, usually at doses higher than those typically prescribed and usually in conjunction with other AAS, is associated with serious safety risks affecting the heart, brain, liver, mental health and endocrine system,” the agency added.

According to the agency, “reported serious adverse outcomes include heart attack, heart failure, stroke, depression, hostility, aggression, liver toxicity and male infertility. Individuals abusing high doses of testosterone have also reported withdrawal symptoms, such as depression, fatigue, irritability, loss of appetite, decreased libido and insomnia.”
