is l-arginine also a muscle builder?

i think maybe it is...

supposedly, it helps release nitric oxide, which stimulates blood flow -- which, if you are lifting weights, you need blood to flow to your muscles both during the workout and in the crucial period AFTER you work out when your muscles repair themselves... if l-arginine can stimulate blood flow post-workout, it can help your muscles grow at a faster rate... but YOU still have to workout, YOU have to lift some weights, or the l-arginine's benefits will not help YOU...
