I love this supplement *
By Steve M. (Canada ) - 5/16/2023
I take circO2 daily for increased energy and overall well-being. I gave a box to a friend to try. When he started his gas-powered lawn mower in the spring to see how well it ran, he decided to cut his front lawn. He felt so energetic doing this, that he decided to cut the back lawn too! He is 80 years old. I gave a box to another 80 year old friend who plays the fiddle at nursing homes to entertain elderly residents. He now plays extra songs to entertain people's requests. I highly recommend this product.

more alert *
By Gary B. (Sadler, TX) - 5/7/2023
I have more energy, but in a subtle way. No instant rush, just a steady increase. Can continue an activity without having to stop and rest.

Leg Cramps Gone *
By Viena Y. (Australia ) - 4/26/2023
I have had leg cramps for few years especially in bed. Have recently tried having Foot Massage Therapy which relieved it a bit but once I started taking Circ 02 I have noticed that I do not have the cramps and have now ceased having Foot Massage Therapy. Will continue to take Circ 02 . Thank You.

Circo2 *
By Noel J. (Australia ) - 4/22/2023
Since using this product my wife & I have noticed a definite increase in our energy levels. We are 79 & 76 so any additional energy is a real assert in our ongoing quest for sustained good health, We would have no hesitation in recommending this product as we have already done with friends trying it out now.

A product I have no doubt about. *
By Donna S. () - 4/20/2023
I have been taking this product for over a year. I have periodically gone a couple of weeks without taking Circ02 and see my heart rate and blood pressure creep up. I have a blood pressure issue, fortunately not too serious, and like to keep it this way; I attribute a big part of my pretty success to Cir02.

Improved Cycling *
By Ben B. (CHARLOTTE, NC) - 4/20/2023
I'm a 74 yr old cyclist. Over the past few years, I have been noticing a gradual decline in my ability to go longer distances at a reasonable pace. Of course, a certain amount of decline is 'expected' due to age. Then I tried CircO2, and began to notice a gradual improvement. Now my ability is once again more dependent on my training instead of my advancing age. At this age, I get a constant bombardment of products pitched; you would think that given enough money, I should be able to live forever in perfect health. It is just nice to find at least one product that seems to do what it says it will.
