I don't notice any difference! *
By Kevin K. (MINNEAPOLIS, MN) - 12/18/2022
I don't notice any effects from using Circ02. I have followed the directions exactly as printed on the box by taking one tablet twice daily with water. I am not sure just what exactly I am supposed to feel after taking this product, but I can say that I don't feel anything different.

I do not plan to re-purchase CircO2 at this time *
By Tim & Nancy B. () - 10/21/2022
I purchased this product to see if it would improve my blood pressure readings. There was only a slight difference in the readings, so not what I was hoping to see. Also, I have started to experience ED symptoms. Again, I am disappointed with the CircO2 for this reason. I shall keep researching this health problem to find a solution.

A word of caution ??  *
By Thomas H. (Lincoln City, OR) - 2/18/2022
The product could very well work excellent, but unfortunately, I have chronic Atrial fibulation & and I am on a blood thinner called Eloquist . So as soon as I started taking CircO2 after just 2 days , I started bleeding profusely & had to discontinue immediately. So I have 2 boxes of them now that I can not use . And I am pretty sure they won't give me my money back for all the unused product . So FYI. Buyers beware !
