It's incredible, I never stop realizing new feelings of low T levels (and also good T levels feelings), or simply reading people who can describe very well how they feel and is always like I feel.
Low T makes you a little tired and a little anxious, yes. But it also makes you more deliberate, gentler, a better father, a more faithful husband (in thought and in deeds).
When I've been at a healthy T level (through TRT), I have indeed been more enterprising and energetic, yes, but also less patient with everybody, and have always done impetuous things that I've regretted later. With TRT, I really am governed more by my hormones than I am when my T is low. You definitely lose the wisdom of the old when your on TRT.
I could notice that with low T I was more gallant with girlfriends (always thinking firstly about her, always taking care of her...). I though this was because I'm like this and I was proud of that, there aren't a lot of guys like this. But I learnt that the hormones are related to all the things. After that, with normal levels of T (on TRT) I could notice I was starting to be like the named "bad guys". I started being more desinterested in taking care of her, the only important thing was sex...My advise
is that you should take the option with which you feel better. You have to compare how you feel with and without TRT and consider all the pros and cons of each in your life.
When you choose, I would investige/test on you adding more meds to attack side effects.
If you choose TRT, first of all you should find the best dosage and application for you if your doc let you do it.
One question: I read above that you used testosterone at 12 years old for one year? Why??
For example, my case. I always though all the low T syptoms I was suffering were normal for me (since I was 16); brain fog, can't concentrate, massive thoughts at the same time, anxiety, tired, feeling like I can't do anything, somedays not even get out of bed, depression, and a lot more... All I thought was I'm depressed, I have no reason, but it must be that. I started suspecting I was low T levels when suddenly all the symptoms get worse, and I saw no progress on gym. Then I searched on internet, made some blood works and... that was my problem (and also Hashimotos). If I would have started TRT before probably now my life would be very different. Low T costed me years of high school wasted, can't study what I want, lose a few works, an important GF... but now I have other goals and the past has passed. The only thing that sometimes I think about is my wasted talent, but it's OK. Anyways, in my case I can't compare the feelings, being on TRT is like be a normal person. The sides don't bother me right now: less creativity (a lot of my creativity came from my brain fog), maybe the future hair loss, future no fertility, maybe a few more, but how I feel is priceless.
