It's pretty much offset any trensomnia.What do you mean by "deep rem"? Vivid dreams?
Afaik there is no such thing as "deep rem". GH does however induce particularly vivid dreams and increase the amount spent in REM along with NREM2 and sleep fragmentation.
High glucose however is really bad. From neuroinflammation, alzheimers dementia, parkinsons, to ... well, everything related to mitochondria dysfunction. I'd really take care of that if I was you.
I fall asleep quicker, the sleep feels deeper. The dreams are more vivid. Even if I do wake up in the middle of the night, I instantly just fall back asleep, wake up feeling more rested.
^^none of which I usually experience. It's definitely had a positive effect on sleep so far, for me atleast. That's the best way I can describe it
