when doing cardio first thing in the morning on an empty stomach , fuel has to come from somewhere ie muscle, glycogen and fat. Fasting increases GH levels which preserve muscle and burn fat. However a beta agonist such as ECA switches off GH release, and your body now as to use another system to break down fat so it raise cortisol which scavangers valuable muscle tissue, it must be said that the ECA increase noradrenaline release which has certain muscle preserving qualaties , but this is far outweighed by the cortisol release . A better thermogenic would be 40g of pure protein immediately before and after training, as this induces hypoglycemia and increases blood amino acid levels both of which increase GH secretion.
As per usual i expect someone who swears by ECA (which i agree burns fat but doesnt do a very good job at preserving muscle) to find fault with my argument, but i know from experience and research that i am spot on
