Based solely on my experience - PSA range is some wide ass range that isn't really that relevant. What is important is what your PSA score on TRT is relative to what your PSA score was when you were not on TRT.
I believe normal is below 4, or something like that. My baseline was .7, nowhere near the upper limit. Once, I wasn't abstinent for 48 hours and it came back at 1.2 - way below the range, but significantly higher than my baseline, so they wanted to retest.
On the retest, one week after the original, it was .9 - so no worries.
So, it's more about where it is relative to the baseline. And my previous doctors wanted 48 hours of abstinence.
I wouldn't sweat it.
