I suffered a major injury to my ankle requiring surgery. After getting the recommended dosage from Jennifer I was able to incorporate my treatments in line with what my doctor had me doing. A week after surgery I noticed the swelling was reduced significantly as well as noticeable healing of my incisions. I was able to decrease the dosage of my pain medication after only 4 days and ultimately was able to completely remove myself from the prescription pain medication after 7 days. My prescription was for 14 days. After each treatment I noticed a significant decrease in blood pressure as well as arise in my oxygen levels in my bloodstream. At the 2-week Mark I was able to start walking without the aid of my crutches. I honestly believe that the use of D'OXYVA significantly decreased my recovery time and allowed me to return to work 3 weeks sooner than my doctor anticipated. I would recommend this product to anyone dad wants to speed up recovery from injuries or surgery.

They were easy to get out of the box and put in and twist and take out and recycle. And they are to expensive.

I have been using the D'oxyva for years. The varicose veins on my legs doesn't show as much or at all. I don't have to stretch in the morning, it gives me more energy during the day. Love it!

I am from Malaysia and have been using D'Oxyva for about six months already. When I started using it I had sleep problem as sometimes I could not sleep well or even if I managed to sleep in the technical sense I felt lethargic in the day time. Since using D'Oxyva, my sleep has vastly improved and I feel more energetic in the day time and can concentrate on my work more than I could have managed all this time. My memory has also improved a lot. Thanks for D' Oxyva for bringing a better change to my health, stamina and productivity. I think everyone should use this product wherher for curing blood circulatory related disease or for enhancement of his bodily functions to improve productivity.

My heartfelt thank you to Circularity management for their support before and after my heart attack. I firmly believe the collateral capillaries that have formed on my heart, bypassing the damage, is a direct result of my using the Circularity system. I'm very happy to report an increase from 15% to an estimated 30% in the injection fraction number( I believe that is the correct name) that has occurred since I left the hospital. The generous gift of treatment cartridges has allowed me to increase my daily usage to 2-3 times per day and the cardiologist now says I may be a candidate for bypass surgery. I will keep the company informed of my progress. Again THANK YOU CIRCULARITY for making it possible for me to write this letter.

This is a revolutionary hand held device that delivers CO2 into the body in a molecular form. It increases oxygen levels to areas that need it. I was recommended by someone to be somewhat of a Guinea pig for my chronic illness (rheumatoid arthritis).

I was amazed at how the swelling and stiffness in my joints went away and I had more energy!

The best part is they market this product also for its beauty benefits. It can help with acne, wrinkles, spider veins, stretch marks and cellulite! Check out Circularity!

I have only positive things to say about the device. I feel more energetic and youthful. I also feel that I have more aerobic capacity when I am doing physical activities from bike riding and hiking to swimming. The device is very easy to use. It is non invasive and takes only a few minutes per treatment. Service has been great each time I have contacted the company. The D'OXYVA device is my secret weapon against aging!

I have found that after only two weeks of using the D'OXYVA system daily that my metabolism has increased and is helping me to lose weight. My sex drive has increased and I am sleeping better throughout the night.

As an Esthetician, I noticed certain scar tissues are healing and the cut that I have is healing really fast. I am very happy with it.

My vision seems to be a little clearer. I have been experiencing chemically induced asthma from noxious fumes from a Nail Salon next door. I noticed that when I am struggling to breath, I will do an application and my ability to breath is noticeably better. Also, I am sleeping better now.

I have problems with sleeping and it (D'OXYVA) really helps me to sleep. I started sleeping really quickly, it helps me a lot.

Normally I would lie low the day after the dermapen treatment and wouldn’t go out at all. However on Saturday, the day after my treatment, I woke to dramatically less redness than usual, less irritation and swelling. So much so that even my daughter remarked that I wasn’t very red. With a little bit of make up I even ventured out to the shops - something I would never normally do until the 2nd Day. I would say that my face looked , on day 1, what it would normally look like on day 3 after treatment.

My husband and I both love this product. One benefit we did not expect was how great our skin looks! My spider veins have all but disappeared and my husband loves how he feels. Recovery from running has improved.

Hi, Thanks for contacting me. First of all, I'm fully satisfied with Jennifer's way of explaining and answering my inquiries about this product. It was a smooth and trusted purchasing and shipping process. Thank you for ensuring that I have received the items safely. I haven't start using it yet.

It works well, proven by improvement of Perfusion Index (PI-Mosimo) on diabetic wounds of Grade Wagner-1 and Wagner-2 after a series of 5 times application. We compared between 15 patients without D'oxyva applied and another group of 15 patients treated with D'oxyva application. Continuing work still on the way in which TcPO2 is also measured, whereby we want to really prove that wound treatment improvement showed by application of D'oxyva. Thank you D'oxyva.

Tôi đã gặp vấn đề về giấc ngủ, bởi vì tôi luôn luôn làm việc vào giữa đêm cho thị trường chứng khoán. Tôi thường đi ngủ vào buổi sang sớm và thức dậy vào buổi chiều sau đó đi ngủ lại. Điều này là rất khó khăn cho chất lượng giấc ngủ của tôi, sau khi tôi sử dụng D'OXYVA tôi có thể thưởng thức chất lượng giấc ngủ của tôi một lần nữa.
