I have no first hand experience on the situation but have heard from MD`s that TRT increases risk of prostate cancer. Personally I think its bullshit! To have a healthy normal level of test, say 900, is going to cause cancer? Google how many diseases that are linked to LOW T in men. If I gonna get sick or cancer, I`d rather be a man with a good test level till the end, than turn into my mother at 70 y/o with a limp noodle and no muscle tone.
