I don;t think any doctor or urologist would be significantly concerned about total PSA of 1.0.
You stated you have never had free PSA evaluated before. You are freaking out because of the free PSA. Based on total PSA of 1.0 there would be no cause to even give you a free PSA test unless you're having prostate symptoms.
I don't see any reason if you discontinue TRT that the free % will change. You have no idea what your free PSA was before you started! There is no way to attribute causation of your free PSA level to TRT.
Only way to find out is to discontinue then get tested again. Personally I would not, but If you do, please report back.
I don't know your reasons for starting TRT, but this seems like throwing out the baby with the bathwater, especially if you did have low T by the numbers plus symptoms. There is more and more evidence that prostate cancer is associated with low Testosterone levels, including that risk increases as a man gets older and his testosterone levels decrease. This is correlation, not causation, but it is compelling.
