Like the independant lab testing label
Very few of these supplements come with the GMP testing label, so if the quality is truly what it says, then this is a great version of this critical supplement.  I can honesty say that over the past year of using various forms of L-Arginine along with some others, I've succeeded in tuning around my periodontal disease.  My dentist asked me how come my gums look so much better and I had to tell them they should look more closely at some of these supplements
