Is there any difference between getting like No2 or Nox2 (pinnacble ripoff) or just buying straight up arginine for this vasodialation and GH release I keep reading about?
probably one and the same with the exception of alphaketoglutaric acid which is a krebs cycle intermediate and therefore exerts osmolytic and lactic acid buffering effects.
i would think if alot extra arginine is taken, the results would be similar. try kilosports.com they have a kilo of arginine powder. That should make it cheap enough to take alot of arginine. Take the arginine and creatine and see what happens.
