It may have been premature initiating testosterone replacement.
I do not think a good physician would put a patient onto testosterone replacement after just two tests, especially given that the first was very suspicious. The second test you had being a retest in my opinion, the result being quite a normal testosterone level.
Another two tests at least, should have been performed to get a good picture of your natural testosterone levels and gonadotropins. Plus a number of other tests to determine if you had other issues which could be responsible for your symptoms. Are you self treating in part?
As I mentioned, the fact you had no libido or sexual difficulties should have made it even more prudent that further investigation was warranted before TRT was considered.
As I also mentioned, high levels of testosterone can appear to fix issues caused by other disease states in the body, for a time, until other issues develop. They have appeared to develop in your case as you describe, in your first post.
it should not be difficult at this stage to cease T replacement and let your body regain natural hormone production. A short run of hCG will bring your testes back from an semi atrophied state relatively quickly, this may hasten recovery, but may not be necessary given the short time you have been on TRT.
