Great product

This is an interesting product that needs to be cycled and let me explain. I took the original NO2 Red, then the NO2 black bottle back in the 90ties when it came out . Great results but diminished with time. Once GNC bought the rights to Red/Black bottles NO2 , I felt like it was a useless product. Then I stumbled onto a product called Saturn by ( I think ISS labs) best ever NO2 product for vassal dialation but more importantly as a natural athlete, the best retentive pump ever . This allows for great motivation and continued incentive to train, especially when your natural . That product is long gone , trust me I checked . Then snap comes along , now at 65 , still training natural and hard . Snap seems to give you that great retentive pump ever, but it seems like it’s a 3 week retention on average then it disappears , not sure why. However I love it and I assume if you take 3 weeks on and one week off , you can get the same results. Going to try on this next round. Its takes about 3 days to get into the system but if your like me , and love to feel solid all day from training , this is the best product on the market. I am not sponsored by anyone , spent 38 years in CPG products and this is 100% honest review.I changed my review from 5 stars to 3 because when i dived into the label its like going back to 1980 lol . I cant even believe this lable is FDA 2025 Compliant. It’s not clear on how much each product represents inside the bottle by each ingredient. While it does not say “propriety blend” it certainly uses the old tactic as if it’s proprietary .Not happy with this style lable ! Also when the distributors pack these for Amazon they should not label over the nutritional panel, they can lable over the bottle seal , it will only add to the product security.LDM

The product really works. Makes me feel a little more energetic a little healthier and at my age it's crucial because you start losing the ability to produce what you use to when you were younger. Better blood flow is important

Works just as it should! Increase blood flow to the muscles. Great pump after a workout!

I bought this originally to help get my mom off her blood pressure meds. She is 76. She says this gives her the best energy boost. She feels like a million bucks. Her BP is now stable (note: this was not the only thing we are using ). She is off all pharmaceuticals for BP now and continues to take this since it makes her feel so good.
