You've wandered into a wobbly bit in the science here, K. There is a sort of a mainstream, sensible consensus position -- that one should worry slightly about
T levels but not actually
do anything about
them one way or another -- not so much because rising T levels aren't seen as a concern but because, as long as the T levels are achieved naturally, patients are unlikely to sue their doctors if thir cancer recurs because the doctors, after all, didn't actually
do anything.
There's also a controversial position that once T levels get much above castrate levels it simply doesn't matter how high that level goes. An analogy I like is that once the water is over your head it doesn't matter, from a drowning perspective, how deep it is; you can drown just as well in 20 feet of water as in 20,000 feet. As for prostate cancer, it says that your cancer is exactly as likely to recur at a T level of 1200 as at 200.
The first position (that T is bad but what can you do?) has common sense on it's side. The wild-assed "T doesn't matter" theory appears to have most of the science (what little there is).
Here are a few links (both feature the same doctor, the lead wildman):
