i dont' interest blood test, (i make 8 blood test year);

Prostate GROW in every male NATURAL with age, anabolic steroid (dht) increase prostate size (infact is used measure prostate in rats to value androgenicity of aas), so will grow MORE in every male that use anabolic steroid.
Only a andrologic control (with ultrasoundand with rectal examination ) can tell you how much your prostate i big...
I fear you were ignoring an extremely relevant aspect for your health.
Know that the day your prostate grows too much, to make you pee they will insert a catheter in your penis
