Testosterone replacement law suits are flying now because a study has shown they increase the risk of heart attacks. They are unsure of the mechanism but some speculate it thickens the blood. If this is true imagine the increased risk taking recreational bodybuilding amounts especially if you are in your 40's or 50's?
hemochromatosis is a side effect of TRT, no doubt it thickens your blood, if you insist on using it it needs to be combined with venesection or donation of blood at least a few times per year, again some people are genetically pre dispositioned towards things more than others, similar could be said to people who have prostate issues in their gene pool. I have been a user in the past but have changed my mind based on forming my own point of view on both pro and against information and my own set of personal circumstances, which is what I would encourage anyone to do, but using blindly shouldnt been an excuse anymore the science is there to assist you with whatever you choose to do,
