Missing the point with Glutamine. First thing in the morning, your body is depleted, or should be, of muscle glycogen. When you eat carbs, glycogen levels start to replenish in liver and/or muscle. So, unless you take a high carb meal before bed, your glycogen levels should be low first thing in the am.
5 g. of Glutamine will not burn fat, Hulk. Will bump GH levels and spare your body from using muscle as energy, especially in a caloric deficit, like first thing in the morning. ECA's also had a muscle sparing effect, kinda like Clen, so use a thermo and glutamine first thing in the morning while glycogen levels are low, will let your body use bodyfat as fuel. Also a product like Xtend (BCAA blend) will be ok to drink on an empty stomach while doing morning cardio as well.
Doing cardio POST weights is also a good time, because of lowered glycogen levels. Those that do cardio before weights spend that time burning up glycogen instead of bodyfat. So, the aminos, glutamine, are not taken for fat loss but to prevent muscle loss. At least that is what I have had success with in past competition mode....
