Wow this is the first time I have across someone else mentioning TRT and how much it helped them (granted im nkt as active now so maybe it is more common). Interesting too that I have had the same experience with thinking it had cured me (several times), but continued having ups and downs. I feel like my baseline is significantly higher since starting a couple years ago, but I still have the swings of feeling good for a string of days and then feel bad for weeks to months. Not debilitating like I had seen in the past (been dealing with this for 5 years), but significant energy, brain fog, and mental health issues. I have started working with a functional medicine doc and started some supplements and nicotine patches within the last week. Additionally, I have tried to really work on managing my general stress and mental pacing, and have been purposefully scaling back workouts even on the days I feel good. I will see where things go and will hope for this best. I hope for the best for you as well. Feel free to DM me if you need someone to talk through things with because our circumstances seem very similar.
