I knew, or rather know, someone who because he couldn't afford GH, or even those GH releases that he didn't have much faith in any way, use to artificially get himself into a hypoglycemic state using Humulin R. The idea was to get his blood sugar so low that it will stimulate his GH production.
It did work in the sense that his IGF level did increased and I certainly saw it first hand when I had to take an insulin sensitivity test. I could see on the chart afterward that after they injected insulin and I started to go hypo, i.e., I was in the beginning stages of blacking out, my HGH would shoot up, and then they would then inject Dextrose to bring my blood sugar back up which caused the HGH production levels to go down.
Except for the risk of dying part, that does seem like an interesting strategy for a poor man's way of increasing GH levels.
