Does anyone hear know at what prolactin level above the norm for a male will start affecting testosterone levels?? I was doing some reading and I found that for males prolactin should be under 20ng/mL. I started sifting through my first set of labs back from 2006 when I was on zero meds and hadnt begun TRT and found that my prolactin levels were 30ng/mL. Is that high enough to affect my testosterone levels.
