Can't imagine why Labcorp would not provide free T units. Maybe suppressed in their portal - I don't access my results that way, so not sure. Suggest you go into the Labcorp test menu, easily found online, try to find the specific Labcorp test code number (if your doc provided them) and look at the units in the sample report, or test details if no sample report is given.
For reference, I put one of my recent T reports here (Labcorp codes in ink):https://i.imgur.com/caumewk.png
You seem about
where I was when starting TRT. T was bumping in 300's and free at or below bottom of standard range. I went on androgel for a couple years, then switched to T-cyp injections. Stayed on that a year or two until seeing what I thought was some rising uPSA that might be related. All along, I was not feeling what I thought were acceptable results for all the trouble. I was also seeing my (self-tested) E2 running way high, sometimes twice the Labcorp high point of normal range. Could not get help from PCP, Uro or endocrinologist to get me on some Arimidex (anastrazole) or other AI inhibitor. The risk of being on TRT with a pos margin was just not worth it to me, though I generally do believe what Morgentaler theorizes. Anyway, to be safe, I just voluntarily stopped it all in 12/2018 and went on pretty intensive aerobics/weights to try to handle things myself. The results I posted above seem pretty positive. That's all without TRT and seems pretty good for a 72 yr old.
Suggest you monitor your estradiol yourself, even if your docs won't. The T from TRT won't help much if you are converting a lot of it to estrogen. This researcher Friedman has a theory that the estradiol is the problem with TRT and PCa, not the T itself:https://www.researchgate.net/publication/305122202_the_relationship_between_testosterone_estradiol_and_prostate_cancer
There is a lot of stuff on one of the other boards, mostly for advanced PCa patients, that goes on about
If your PCa advances, and I'm hoping it does not, you may find an additional home on that board.
You seem like a thoughtful researcher and capable of absorbing complex publications and data. But if you are going to pursue TRT and want research or medical help deciding whether or how much of it to do, and for how long, just be generally aware that definitive answers may not be forthcoming.
A fellow PCa survivor and I have been going round and round with this stuff the last two years. He (a doc himself) has even been up to Mayo for one of those multi-day visits, many tests/labs of all sorts, multidisciplinary team of experts to go over everything. Even so, between us, we have recently realized and admitted to ourselves that we are not going to get help with all of this (TRT, PCa, possible recurrences, etc.). We think there is just no one doc that can tie it all together, and the separate specialists are just out there in their own worlds. Maybe you will fare better, hope so, but you may need to make future decisions based on "gut feel" rather than assured medical advice.
The possibility that TRT could help with PCa is pretty exciting. I had this one bookmarked away:https://pubmed.ncbi.nlm.nih.gov/31498469/
