Try not to get too bogged down by what I call nutritional micro-management. Too often we worry about trying to increase or certain hormones and dont really realize that the % change would be so small that it wont really matter at all toward our progress. And sometimes it is even counterproductive in other avenues. Like TC pointed out, fasting will increase GH. But who cares?!? If you fast you will lose muscle anyway.
With that said, I agree with Steve that substrate manipulations will affect wt training hormones minimally. Endurance training is another issue altogether.
In response to your questions:
"Will the plain glutamine, powerdrive or MD6 raise my adrenalin and noradrenalin levels?"
Yes MD6 and PowerDrive may increase stimulatory hormones like epi and norepi. So would the ECA stack. This would help with strenght and power as well as facilitating the release of stored fats.
"If so, will these raise my insulin without a meal too?"
No they won't. These hormones act to increase blood glucose as well as glycogen use in the cell. Insulin has the opposite effects. So DURING training you dont want or need increased insulin. In fact if you inject insulin during a workout you could go hypoglycemic and die. And again, as Steve pointed out, exercise blunts insulin release as the activity of it's counter-regulatory hormone, glucagon, predominate. You dont want your cells greedily sucking up blood glucose indiscriminantly during a workout. His point is that you dont to eat a big meal and release all that insulin before training and walk into your workout with low blood glucose. That would surely lead to a crappy workout.
You are using muscle glycogen during wt training anyway. Remember that there is minimal fat burning during weight training no matter how you manipulate the hormones. So there is no "wasting glycogen" as you imply. And this has no impact on recovery.
In terms of practical suggestions, forget the epi and norepi thing. You'll get those increases anyway. Forget the insulin manipulation as long as you dont walk into the gym with low blood glucose you are ok. What you should do is eat 3-4 hrs before a workout. Take your MD6 or Powerdrive about 45 minutes before. Then have a snack (protein shake or bar) about 15 minutes before. Train your butt off and you could even sip on a carb drink during (as steve said to stabilize blood glucose and to prevent protein breakdown). Then do the same postworkout meal you are doing now. After you leave the gym is the time to worry about jacking up insulin (which you are probably doing well with the 150g of carbs).
Hope this helps.
