I’ve never run high GH. 4 ius daily is around what I stick with, and I experience the best quality sleep while running. Having served in the Iraq that’s a pretty big deal for me, so the numb and tingling hands doesn’t bother me much as the pros obviously outweigh the cons.
The only time issues from numb hands presents itself is when masturbating, which obviously shouldn’t be a priority for a grown man. With that said, bad hands and arthritis run in my family, and my hands hurt from just scrolling and “typing” on PM for a little while on my phone. I guess I should try pop socket or something like it.
