Interesting.

But, this is just a review of insurance claims. They found (I assume - haven't read the study) a correlation between heart attacks and testosterone supplements. Doesn't show causation. Maybe guys who didn't feel fit were more likely to use T, and maybe they didn't feel fit because they weren't.

FDA will examine the clinical trials of T products, which should have been randomized and blinded, and look for a cardiac signal. Also they will review the preclinical data. Maybe they will require a new randomized study.
