"this is my first NO product ive used and i must say the results are great i look more vascular and can actually feel better circulation from using this product. ive been on it for 3 weeks now and it works. dotn expect this to suddenly make you ripped and grow tons of muscle, i use it as a supplement along with a solid workout routine and a very clean diet. it wont make you gain muscle over night but it does what it claims and you cant beat the price. take this stuff along with whey protein and creatine and you cant go wrong."

"If you’re looking for a NO product this is the one to buy!
Exactly the same ingredient as the higher cost "name brand" at half the cost.
In weight lifting blood flow is paramount for results and NSI NitrO2 gives me the pump and increased stamina needed for intense workouts."

Weird dreams..., May 14, 2008

"While using this product, I had weird/disturbing dreams almost every night. For the first three nights of taking the supplement, my dreams were so vivid that I was exhausted when I woke up! After a while, the dreams began to upset me too much, so I decided to stop taking the supplement (Soon after, my dreams had returned to normal).

Now although that seems crazy to tie the two together, I did some research via Google on similar products such as Nitrix and some people had reported the same issue.

As for the effectiveness of the product, I did notice it made me more "veiny" whenever I worked out or lifted anything. But it wasn't a huge difference, and certainly was not worth the sleepless nights.

So far I've done really well with NSI's CEE (Creatine Ethyl Ester). I feel I definitely have increased muscular endurance and development because of it."

Helped me improve my endurance, October 19, 2007
By August from Houston, TX

"I play soccer 3 times a week and needed a product that would help me break through some endurance barriers. I would say it took about 2 weeks before I really noticed a difference. I use this product in conjunction with the NSI ToCoQ10 and they seem to compliment each other really well. I follow the recommeded dosage (3 tablets) about 2 hours before a game. On other days I just take it after a meal. Works great. Highly recommend. No problems on the stomach."

"I have had Type 1 diabetes for 41 years-one of the most disastrous of many complications can be lower limb amputation, as well as leg and foot ulcers and infections. Have noticed improved circulation in my legs and feet since using NitrO2, and no more cold feet. Have also experienced a needed drop in blood pressure. NitrO2, used with Magnesium aspartate and Benfotiamine-all from NSI-have eliminated peripheral neuropathy symptoms!! All diabetics should use these products!"

"NitrO2 has officially replaced my Universal Animal Pump. The price, the results, the pump, are completely on a whole other level! The reason? NSI uses a high quality Arginine AKG with little to no overlap or filler.

With such a clean ingredient list, this supplement doesn't necessarily need to be taken 30-45 minutes prior to exercise. I take Nitr02 first thing in the morning on an empty stomach and in the evening, 2 hours after dinner.

The price is absolutely fair for the quality of the supplement and the effectiveness. Don't pay for advertising, don't pay for packaging, pay for quality."

"Comparing this product to Other NO2 products, You cannot even compare. This product works as well as and if not better than NO2 supplements in the price range of 50-60 dollars. Don't waste your money on advertising costs for big companies, Try this product and see for yourself."
