Thanks for the reply everyone!
The medication I am on is actually Suboxone. I was on oxycodone for years and it eventually became ineffective, so the suboxone was used and it's been working great for the past 6 months, besides the low T of course.
I'm hesitant to do any form of real test because it sounds like I'll be locked in to that treatment for life, but I'll eventually come off the opioid if my condition clears up and then I won't need a TRT. Is it true that real test is a life long commitment?
In the meantime I'll dose clomid 12.5mg EOD and drop the AI and test labs in 4 weeks. Is this a good approach? And if that doesn't work maybe consider test with hCG.
Hopefully someone else will comment on calibrating your AI with clomid (you may even want to start a new thread). I don't have any personal experience with them -- but using less clomid and AI is the approach that I would take.
In terms of TRT being a lifelong commitment -- my doctor says that natural levels will resume 2-4 weeks after stopping. Anecdotally, it definitely takes some guys longer. You will hear some people say that there is long term impairment, but it is hard to judge if this really happens (my doc says no, but maybe for some guys taking steroids). Fertility does take longer to recover (up to a year), and there seems to be long term impairment for about 1% of patients. Using HCG will help counteract this, as others have said. But I don't know if the effectiveness has ever been studied. I also wonder if taking HCG alone (ie, HCG monotherapy) is actually better for fertility than Test + HCG. In theory it should be, but I wonder if there is really a practical difference.
If you expect your cause for low T (opioid use) to end in the not-to-distant future, then it makes sense to give clomid another shot. It is the easiest therapy to come off of (at least for guys who don't have serious side effects).
I am glad to hear that suboxone has worked for you. May I ask, what type of pain do you have?
For my own pain, I plan to give Low Dose Naltrexone (LDN) another shot. I tried it before, and all it did was give me sleep problems. I am hoping that with TRT it would actually work, and with little or no effect on sleep. Also, there is a female fertility study showing that women who did not respond to clomid alone would ususally ovulate with clomid + LDN. This suggests the possibility that that LDN could improve the effectiveness of clomid in men. It's a real long shot, but might be worth consideration for some guys (and not necessarily the OP, I am digressing here...)
