Quality product. Worth every penny
This supplement really works. You can feel the difference in about an hour. You will notice increased vascularity and better pumps when you work out. It also helped lower my BP and increased my erectile function. I recently bought some cheaper stuff and regret it.

Best nitric oxide supplement I have found
I used to get a N/O supplement from a health store that was geared as a pre workout booster. They discontinued it, but I had such a good reaction to taking it, that I tried a few others. None had any noticeable effect whatsoever until I found this one. This one noticeably improves lung function and lowers my blood pressure while giving me energy and stamina at 1/3 or less the price of the one from the supplement store. This will be the only one I buy from now on. Thanks for providing a good product for an also very good price.

Great Stuff, Also Works Great For us Older Men for sexual health
Well I'm over 50 so I'm not using this to work out .. the little blue pill is the same except this is increasing your ntric acid levels back to where they should be when you were younger so you function as you did younger .. oh and it's a great amino acid complex .. I'm a professional touring billiard player so I'm waking the table training about 7 hours a day and I can see the teardown in my shoulders ..

There are better alternatives.
I was hoping this would be a cheaper alternative to BSN's N.O. product. But it appears this one will fall short of that task. While it does take a while to work, it will work but only slightly. It didn't really boost my workouts but it did raise my vascularity levels. Overall, I would not buy this again but it may work better for you.
