  2. Jenna K (store manager)

    Using it for 2 months now for my leg pain caused by varicose veins. Was instructed to follow twice a day application. So far, the bulging veins are less visible and I can barely feel any pain even after standing for hours!

    • doxyvaseoassist (store manager)

      Awesome, Jenna! We hope to hear from you again. Remember to keep your maintenance course on a weekly basis to enjoy the long-term benefits. All the best!

    Just started treatment will rate later

  5. Quennie (store manager)

    At first I thought it was doing nothing for me, then was told that I should follow twice a day application for at least 4 weeks, then I did. After 4 weeks, amazingly my pain went away. Then I was advised i can now do once a day like a maintenance then gradually to 3 times a week after a month.

  6. Marvin M, (store manager)

    Simply amazing technology! Used it for my ankle pain. I am runner until I fractured my leg. I thought it will take time to be back running again until I searched for an alternative pain and healing therapy and that is how I discovered D’OXYVA. It makes sense, the science behind it. I even asked my therapist if this would help me recover and he agreed that improving microcirculation helps with faster recovery, and in just 3 weeks, I’m back on track! Thank you to the team behind this amazing product!

  7. David H.DePathie (store manager)

    Best Platform to buy any health kit. I contacted them for my diabetic management kit. They ensured the delivery services and best quality product.

  8. Roger Jacobs (store manager)

    I became a client 2 years ago after seeing the amazing transformation in another one of his clients. After I started using the D’OXYVA, I felt a major improvement in my breathing because my sinus issues had cleared up. After about 6 months, I realized that my muscles felt better and I was gaining my muscle mass back. I have had a major reduction in pain and inflammation throughout my body. Now I feel physically stronger. I am still using D’OXYVA .I know that the D’OXYVA applications have helped my body to feel good and healthy again.

  12. Scot Clark (store manager)

    While I would rate your product exceptional but pricey, I did not order any. I received two e-mails confirming shipment. Which I did not place . (which never came) and now am being asked for a review…. still having problems with your internal systems I see.

  13. Jim J (store manager)

  14. Michael James (store manager)

  19. Antonio (store manager)

    ever since I used DOXYVA, I’ve been sleeping well and getting a really good quality of sleep! Which results in my good performance at work. Great product!

  20. JHONNY HERNANDEZ (store manager)

    Many people set unrealistic expectations of themselves in too short of a time-frame. Weight and muscle gain happen over months, years, and decades of work. Six weeks is a small amount of time to see major gains, but your muscles should feel a little firmer and maybe be noticing some shape or definition to the muscle you have. Thanks D’OXYVA, I see some change in 4 week.

  21. Robert Clark (store manager)

    D’OXYVA is like a friend, a mentor, a guide that alerts us and helps us in tracking our progress. It is a great way to motivate yourself.

    Malignant is dangerous, where blood pressure stays very high like 200/120, 230/140 and some time as less as 160/100. It’s generally difficult to treat. All end Organ damage will manifest within 5 years if bp is not controlled adequately. D’OXYVA counters primary hypertension by increasing the blood flow with fresh oxygen-rich blood.

  31. Sophia Smith (store manager)

    Fast delivery! I am using D’OXYVA for 6 months now to keep myself fit and healthy. It enhances blood circulation and improves immunity as well.

  35. Kate Wilson (store manager)

    I have introduced D’OXYVA to a number of my patients till date. I have received positive feedback from most of them who have used D’OXYVA. One 59-year old patient was in ICU,incubated and had developed bad sore which needed many debridement. His family discussed with me on his condition and upon my advice, agreed to try D’OXYVA, to be administered three times a day. The wound recovery was tremendous. The patient and his family are very happy with the recovery progress. I have also introduced D’OXYVA to other patients. This is exactly what I was looking for. It transforms my current best efforts into a permanent way.

  36. LUKE MARTIN (store manager)

    Everything is good with this platform. They have right product and best delivery services. Performed far better than my expectation.

  37. Justin Burton (store manager)

    Natural ways are always helpful and safe for the people with hypertension, but may not be easy to follow all and practice regularly. It may not be effective if bp is very high. Thanks to Mr. Steve who recommended me D’OXYVA.

  38. Friz Freleng (store manager)

    I am seeing an increase in muscle mass due to the D’OXYVA. People suffering from muscles pain,shoulder pain, etc. must be regular with certain exercises. D’OXYVA helped me to get off muscles pain. I love D’OXYVA.

  39. Jared (store manager)

    Web interface is fantastic and smooth working better than competitors. Their customer support is well organized. It saves time which is much precious. Nice job D’oxyva.

  40. Mitchell Wilson (store manager)

    A fitness tracker can change one’s life and help them to stay motivated and focused on their fitness goals. However, many people get bored with these fancy toys too quickly. D’OXYVA is an alternate of it.
