I understand both sides of the debate but went with TRT. Two yrs undetectable psa. Couldn't find any real evidence that TRT above the saturation level was harmful, but did find some studies indicating it helpful. Uro said there is big shift amongst the uro community in thinking about this.
T-level was about 225, should be about 500 (give or take) for a 65 yr-old. Starting to feel a lot better on it than off.
In doing my research, I saw this interesting question posed to the hypothetical doctor who has a patient like me (Robert) and ten other similar post-ralp patients, but assume their T-levels are already at the normal 500.
Q: "Dr., you advise against raising Robert's T level"?
A: "Yes, correct"
Q: "Then, you are also actively working to lower your other ten patients' T-levels from 500 down to 225"?
A: "No, of course not"
Q: "And why is that"?
A: "Well, because, um, you see, um.. Hmmmm, I don't know..."
An interesting way to look at it.

Yes, well put and indeed a very interesting way of looking at it. If a T of 300 is friendlier to PC cells than a T of 200 or 100, and since it is quite likely most of us after whatever treatment still have a few PC cells hiding somewhere, wouldn't it make sense to try to drop every ones T lower? If you are very hesitant to raise it because of the dangers you believe are associated with that, then why not always try and lower it?
I'll be glad when we get some solid large number research on this. What does animal research show? Because wouldn't it be something to find out that having higher than low normal to below normal(but above castrate) levels of T not only did not hurt, but actually helped in the battle against PC? Right now I am not seeing any evidence that us guys with low normal or slightly below normal natural levels of T have any advantage in the PC risk, and maybe even just the opposite. Clearly having near zero is helpful. Not at all clear if raising your natural from 200 to 400 or 600 is harmful. There should be a ton of evidence for this, but I don't think there is. Any body got any evidence on the harm of higher T levels compared to low normal or some what below normal?
Here are some things that the members here might be able to supply info on:
1: For the ones here who have dared to step into the T therapy after PC world: how did your PSAs do, and for how long have you supplemented? If there was any rise at all, did it keep on rising over time, if you didn't stop immediately on the 1st rise?
2: For those who have blocked T production with drugs: what kind of time is involved in getting your T levels down to near zero, or does T drop quite rapidly? If there was a time in between the start of therapy and zero T, was there a time when your T dropped from say 400 to 200 and then 100? If so, what was happening with your PSAs along that journey? Were they dropping proportionately?
3: Are statistics available ( they darn well should be IMO) on large populations for T levels, and free T levels, vs PC diagnosis? If raising T from low normal levels to high normal levels increases the risk for PC or higher Gleason diagnoses, then it should show up in population studies.
These two studies actually show that T is lower in PC pts, particularly high grade PC, but their conclusion is that PC lowers T levels!
www.ncbi.nlm.nih.gov/pubmed/11304729 ( this one also showed a lower estradiol- estrogen- level with high Gleason PCs. I had both a low normal T and etradiol. They suggest it is the PC that is lowering both of these hormones)
www.ncbi.nlm.nih.gov/pubmed/12386917Here is one that indicates higher FREE T increases risk for PC:
www.sciencedaily.com/releases/2004/05/040510012315.htmHere is one indicating lower levels of total T are trouble, and higher levels are not:
