this stuff never did interest me. too much info can be found like the following from tom ventuno
Dear Tom,
I have recently stumbled onto a new product at GNC while looking to buy creatine again to hopefully help me show better results and thus help me stay more motivated. The new supplement that I found was NO2, Nitric Oxide. I bought a book that was written by the creator of the supplement, which extols all of the virtues of this new product. Knowing that people will say anything to sell product, and being a wary consumer, I was wondering if you know anything about this supplement, and could tell me if it is anything that I should be considering.
I haven't personally done any research on NO2 yet, although from what I've heard so far from trustworthy sources, there isn't much research to speak of. Naturally, I'm skeptical of NO2 as I am of nearly all these new "wonder supplements" that come down the pike with tons of hype.
Paul Cribb, the resident supplement expert from AST Sports Science, wrote an article about NO2 on the AST website last October: "NO2 supplements: Big claims, ZERO science - NO2 ways about it." (I got a chuckle out of that title).
Cribb Says he's not sure where this research on NO2 is coming from, but he thinks it's from "Alice in Wonderland." Cribb concludes by saying, "Money spent on these supplements is money flushed down the toilet."
Will Brink, another supplement expert and author of Diet Supplements Revealed (whose opinion I greatly respect because Will is an independent source and he's a STICKLER for the facts and for unbiased research), did not even give NO2 a listing in his brand new book, Muscle Building Nutrition.
In Will's forum, someone asked about the NO2 book written by the inventor of NO2 (which made all kinds of wild claims for the product). Will answered, "When the inventor of a product writes a book on the product, would you consider it an unbiased source of info?"
Will continued, "There's no real data regarding increases in Lean Body Mass (LBM.)" Then he concluded, "Follow your diet and training for a solid 6 months to a year, THEN worry about the greatest wiz-bang supplement. People seem to be always looking for the next great thing, vs. getting down to business."
I couldn't have said it better myself. You can check out the AST research article here:
