Im sure this study has been posted before, but for those that missed it here is a study showing the opposite of what is being touted in the media regarding testosterone and heart attacks. This study claims that maintaining T levels above 550ng actually reduced cardiac disease risk. Note that they tested estradiol levels, which was lacking in the inaccurate study recently published. In addition, they found positive correlation between T levels are type 2 diabetes risk. This study was done over 5 years and analyzed all kinds of markers, including SHBG.
