This was my biggest concern starting TRT, and the reason for some of my concern now that I'm not feeling any different than I did pre-TRT. I understand that this may seem like self-doubt, etc that is indicative of low T levels in general, however I think some of this concern is reasonable.
In my case, I was far from feeling terrible pre-TRT. My primary concern was ED - this was a new thing, and I'm married and have a great relationship with my wife (basically safe to rule out anxiety/psychological factors). Also, decreased energy levels, far less enthusiasm in general for activities that I used to get pretty excited about, and occasional moodiness that were not characteristic. But I still managed to get to the gym a few days a week (although with less results) and generally live life. In summary, the feeling I had was that life was ok, but almost like someone had turned the volume down. Also of note - puberty was late for me, and I've always looked young for my age - my doc seemed to think that was also relevant.
My doc said he thought it was worth trying TRT and that if it did not work for me or that if I saw no benefit, I could simply stop and things would go back to normal eventually. Having read through countless threads on various forums, it seems that it does indeed take a lot of time (up to a year) to realize the benefits of TRT. However, my concern is that after a year plus with a shut down HPTA, will simply going back to normal be an option? And if the feeling I had the past 2 weeks is not the norm, and this third week feeling might be the norm, then is it all worth it?
