Testosterone replacement therapy (TRT) supplements have recently been found to cause severe cardiac complications in some men. Side effects of testosterone have been reported to include heart attack, stroke, pulmonary embolism, blood clots, and sudden death. New research published in the medical journal PLOS ONE found that men who took testosterone boosters were at least twice as likely to have heart attacks within 90 days of beginning treatment than men who did not undergo TRT.
