A member asked:

I want to know about l-arginine benefits and muscle gain. i'm doing hiit (high intensity intervals training) every day, focus t25 workout.

A doctor has provided 1 answer

See details: Studies are contradictory. Some suggest that L-arginine may increase levels of growth hormone while other studies have not found this to be the case. I would avoid this supplement and focus of your resistance training and a high protein diet.
