L-Arginine is the most useless ingredient on that list. I would much rather see Citrulline Malate (not the malic acid-bonded CM in this PWO) or L-Norvaline to deliver the "pumps" (not that the pump even matters, some people just like the feeling)
This is quite an interesting study (full text BTW), but this appears to examine only acute arginine consumption, rather than regular dosing. Do you know of any studies going into that? I ask because as recently as this past spring my doctor (who teaches at Harvard Med, so I'd like to think she knows what she's saying) was advising in favor of chronic arginine usage. My understanding from her, as well as documentation like the stuff I cited, was that it needs to be at a consistently high concentration in your system over time to have the desired effect. If that's something that's been tested and disproved, I'd be very keen to see the study, but my own search didn't turn anything like that up.
You do have a very solid point though, that this product, if used independently of other supplements, would by no means produce enough arginine load to have a real vasodilation impact, if such a thing does happen in the first place. (Given the amount I've seen over time in favor of that position, I'll still tentatively remain in that corner for now.)
(P.S. That study also tried to draw a direct relationship (or lack thereof) between arginine, NO, and muscle growth. I've never seen anything claiming anabolism could be directly attributed, so I found that odd. Even the study itself mentioned only one other paper had been produced that even touched on that idea, and that that was in a rabbit. All this in consideration, I think it may be the initial goals of their research may have been skewed in a slightly different direction.)
