Nitric Oxide Saliva Test Kit (Tube of 25 Test Strips)

The kit works just fine. The strips performed as expected. The larger kit allows me to test for a longer period of time to be sure my Nitric Oxide is at an acceptable level.

After using a few of these strips, they are not accurate, they go from one extreme to the other. I know because I have another test strip that is accurate and also to blood tests I get from time to time for my Nitric Oxide levels in my blood. Maybe is was just this particular bottle. Very disappointed and a waste of my money.

Strips tell you your oxygen levels--since I started taking nitric oxide in the morning, my O2 levels are in the normal zone and my energy level is very good. I was sleepy all the time before.

This product is helping me refine by healthcare choices. I'm determining if my supplements work or not! This is a great tool for anyone interested in keeping and achieving optimum health.

I USED THE STRIPS SEVERAL TIMES AND I NEVER GOT MUCH CHANGE IN THE COLOR. I EVEN USED IT AFTER INGESTING L-ARGININE AT DIFFERENT INTERVALS AND IT DIDN'T REGISTER ANY CHANGE, WASTE OF MONEY.

works as intended. But really not needed if you take N02 as directed you'll get where you need to be

Tested on 2 different people. Big difference. One with low reading has circulation problems. Believe it worked just great. Recommend it highly

These NO2 strips work very well, no problems with description, packaging or delivery.
