Adrenergic Effect on Muscle Growth


#1

I would really like some insight into this question: Does adrenaline/adrenergic stimulants block the inflammatory response to training and or block muscle growth? I know that they can cause vasodilation/vasoconstriction, and supress the immune system, and might also cause higher cortisol levels.

So if something causes vasoconstriction, but raises blood pressure is it going to allow or prevent the inflammatory response in a trained muscle? Is it going to cause tissue necrosis, increase cortisol or reduce the effect of the immune system at clearing out waste and dead cells.

In short, does using edrenergic stimulants (like Ephedra) hurt muscle growth.
