100% agree, i noticed a big difference as soon as i started incorporating fasted cardio even when bulking. Training days i eat more kcals/carbs, rest days i eat less kcals / and a little bit more fats then on training days. With HGH i found it’s all in the dosing, yes it helps to have some days off but it seems like there is a small line of a maximal effective dose before insulin sensitivity gets losed.

And also the small things add up... like apple cider vinegar, chromium, cinnamon. The more advanced you become the more pronounced the effects of it going to be.
