does anyone here take pure L arginine and get any positive results? I have read up some and get different stories. I read that taking 3 grams per day will increase human growth hormone in males and open blood vessels for a better pump. I have also read that no matter how much you take it does nothing without the proper delivery system or so the guy that created the original NO2 from MRI says. I was thinking about pickin up a bottle and take 3000 to 4000 mgs a day and see if I get any results.
