Having that happen abruptly, imo its sign of something else.
Also, You're implying you were doing these tests through all the years.. why? No "normal" person does that, are you having other "preexisting conditions" as well?
I have seen drugs destroy people’s bodies and lives. Were there other factors? Yes. Did drug use amplified the other factors? Yes. Does it mean it’s same for everyone? No.
But, the sentiment remains. Putting a mood altering substance in your body can change it in profound ways; be careful.
Maybe, but if you are describing something that naturally happens as you get older, its a reasonable question.
There was a post on HN from a (otherwise seemingly smart) user who blamed cosmic ray(s) for heart condition his daughter developed. Even otherwise rational smart folks do tend to end up in weird mental bubbles/tunnels for lack of better words.
TRT has mostly reversed the damage but I will need to take this for the rest of my life. My levels were always upper 500s/low 600s (590 ng - 610 ng). Then recently, two years back or so, my total testosterone dropped to below 200 ng/dl, as low as 190 ng/dl. Estradiol was very high (triple digits) as was prolactin. My point in sharing all this is that your body WILL maintain homeostasis at any cost, even if it means grossly adjusting your hormone ratios.
Be cautious with anything you put in your body.
