I've seen the ads as well. Being pushed a lot by GNC, probably because they got a good deal on a bulk order. As with most of the Nitric Oxide boosters, they are charging way too much for the results you can expect. If you read the supplement facts, it pretty much has the same ingredient breakdown as any other nitric supplement that you can pick up for less than half the price. Compare it to Six Star Muscles N.O. Overdrive or Dymatize's XPAND and you'll see that paying $70 isn't worth it when $20 will get you the same thing. And since supplements are hit or miss based on diet/exercise and simply how you body accepts them, $20 is a lot easier to throw away on something that may not work.
