Personally I don't believe it's worth the price, I made my nitric oxide stack nice and simple and it's working great for me. I'll post my thread on it and you can take a look.
No I didn't feel any results from it. What I feel the most results from is L-Citrulline Malate, it really makes a difference for me. Some men do not like the malate because of the sour taste, but I really like the taste of it too.
