I was curious as to what the proper dose is for L-Arginine. I bought some at the Vitamin Shoppe and 2 pills contain a total of 1250mg of L-Arginish and 750 mg of L-Ornithine. Is this a proper dose or should I up the ante? Also, do the members here supplementing with L-Arginine also use L-Ornithine? I know that body builders always stack the 2 together, they are supposed to work synergistically.
