Does a small amount of insulin stop all GH? Or is it more complicated?
Like all hormones, the chronic is far more important than the acute.
I think he means your general GH and insulin levels are more important and effective over spiking one or the other.
I've noticed you have many questions about this topic as though GH is the holy grail. Insulin has a very anabolic role as well and, like GH, maximizing it's efficacy is important. While the whole high-GI vs low-GI is a separate debate, neither side is denying the fact that you need to have some insulin response to store glycogen and repair the muscle. GH is mainly elevated during the night hours and worrying about your GH levels during the day is a tad absurd. Worrying about your insulin levels and it's potential to store fat is far more important than having chronically elevated GH.
Hows this for an example - your testosterone levels immediately after a heavy quad/hams workout is significantly lower than before. Does that mean you shouldn't do heavy quad/ham workouts? No, because part of why its lower is that the testosterone in bloodstream is binding heavier to the AR and just isn't produced as fast as its being used, which is a good thing.
Insulin is also involved in muscle building. Is there info that suggests the theoretical increase in GH vs the reduction in insulin would yield a net benefit in the overall goal of gains from the gym?
What the vets here are trying to say is don't get hung up on the microscopic level at the expense of the big picture. You will just end up chasing your tail.
Train hard, eat enough whole food, and get enough rest. Let your body worry about the micro details.
I've become the most muscular person I know, and I got that way completely steroid and prohormone free, so I just whant to optimise my healthy, natural hormone levels. I just whant a little of the GH I earned through hard work to partition a little fat after I train.
