Great post. As mentioned, this is very similar to how many steroid users self-treat in their "post-recovery" cycle. (Sometimes it does not work for them and they lose their T production forever.)
Your commentary about the depression leading to secondary hypogonadism is very interesting. Who knows? You could be right there in some cases - the power of the mind is poorly understood at this point. Of course, I would add that it could be a chicken and egg thing. In other words, how do you know that you didn't get secondary hypogonadism - don't ask me how - and then that initiated your depression? I mean there are things such as a poorly developed hypothalamus that can lead to secondary hypogonadism. Who knows? Can an abundance of excitotoxins do the same thing?
But I actually hope I'm wrong. I hope your theory is right, because this is a case where I have long thought that doctor's practice was very lagging behind the research. For example, it is well-known that many stressors can whack the HPA and lead to secondary hypogonadism. Brain injury, infections, high inflammatory conditions, trauma, brain injury, etc. can all lead to secondary. And, although I don't think it is super well-documented in the literature, severe emotional stress has been known to do the same. I will try to find some examples hopefully of that.
But it is exciting imo that your doctor was willing to experiment with this. Imagine: years and years of HRT can perhaps be saved in many men by first attempting the above protocol. This could be a big savings in terms of time, money, side effects and so on if it bears out. Let us know if it "sticks"!
Note to anyone overweight: Obesity can induce secondary hypogonadism as well, but this does not apply to this young man.
