This is very interested thread also. I think @zzz123 is definitely on the right track. These are the main aspect that we should focus, also on my opinion. Gut and adrenals. But on top of those we should support the body from many different directions in order to archieve any progress.
My labs referring to the original subject:
(These are 8 months after crash) ->
GH: 0.28 ug/l [range 0-3]
IGF1: 54.3 nmol/l [range 11-35]
Prolactin: 287 mU/l [range 86-324]
TSH: 2.0 mU/l [range 0.27-4.2]
So I have highish prolactin but check my B6 and B12 labs ->
(These are 17 months after crash) ->
B6: 338 nmol/l [range 35-110]
B12: 255 pmol/l [range 180-700]
My advice is that before you supplement anything, get tested for the particular parameter.
For example it would be insane for me to supplement any kind of B6.
What comes to the growth hormone, I remembered looking this interesting video at some point ->
