Did you try kisspeptin at all? If so what were your results? To me it seems like kisspeptin would be the way to go because it's been proven to raise lh and fsh plus they think it plays a part in libido, mood and even metabolism. I know there's not a lot of info on it right now but I did come across a study that gives the dose they used and the lh and fsh results from each dose.
I do think you're on the right track with this. I've always thought that trt shuts down some vital component that we need to feel normal but I always came at it from the angle of balls being shutdown therefore they aren't producing something that we need.
I'm thinking about trying just kisspeptin first at different doses and see what happens. I've still got a lot of reading to do before I decide to try it tho.
Another thought that I've had, if kisspeptin, gnrh or something similar is what we're missing then it seems like if we quit trt then you would think there would be a window, even a small one, where our T is high enough and we're also producing grnh and we would feel better even if just for a little while. MYbe, maybe not but I do find this interesting.
