How do you use the 2-in-1 Nitric Oxide Test Strips?

Step-by-step instructions:

It’s quick and easy. Test first thing in the morning before you eat, drink, or brush your teeth.
Simply put the end marked “saliva here” on your tongue for 5 seconds, then fold the strip in half so the pads meet, and press the two ends together for 10 seconds.
Match the color on the test pads to the key printed on the tube for your results.
