First time I used Nitric and I definitely felt significant results during my workout. I will continue to use it.

Thanks for your feedback!

Using for 2 weeks, have not noticed any difference and it also raises the blood pressure.

in my country that kind of suplements are very expensive, and it is hard to get them from usa, however it is the best way to buy stuff from internet. it was my first order from iherb, your weight calculater was very helpful. im so happy to chose you. thank you very much. Selim Suludag

I am a 62 yr. old male. I participated in two 5K races this year. I used this product in training--could tell a very big difference between the days it was used as opposed to the days without. Used it on race days and won medals both times. Took it about 30 minutes before workouts (or races) and it gave a detectable fizzy sensation shortly after I would compare to a fuse being lit. By event time was decidedly more explosive than I usually am with endurance greatly enhanced as well. Did not notice any negative side effects--no stomach or blood pressure issues.

Thanks for your feedback!
