I don't understand why people keep claiming that arginine only works if used I.V.
Here is one of many showing the effect both I.V. and orally:
http://www.ncbi.nlm.nih.gov/pubmed/9833603
Of course the I.V. increase is greater than the oral, but the oral is still significant.
Now that isn't to say the nitrate isn't better, but I haven't seen a study yet that shows that the nitrate to nitrite to NO pathway is more effective or effecient than the arginine to NO pathway. Under normal biological conditions, arginine converts to NO through the NOS enzyme (which does not break down NO as some product sites still claim despite my emails cough cough lol).
Also, was that UCLA study published or do you at least have their findings? I'm not trying to be a **** or pick on you. Your product could very well be all it claims to be and more, but most of us on here like to see numbers behind claims. Otherwise I may just go to GNC and buy whatever protein Ronny or Cutler are blindly advertising for these days lol.
