D'OXYVA® (deoxyhemoglobin vasodilator) delivers consistent results measurable in seconds. Take our guarantee challenge and you may earn free products!

  • 1. Check your results (e.g., blood pressure, heart rate, blood glucose, skin perfusion pressure, perfusion index) at the point of care, via remote patient monitoring at home, or on the go by various reliable FDA-cleared non-invasive diagnostics.

  • 2. Send your verified results to us before, 30 minutes, and 60 minutes after taking a single D'OXYVA delivery of 5 minutes.

  • 3. We will refund your full D'OXYVA purchase price if you do not achieve any improvements (proof of purchase required, improvements measured from absolute baseline without taking D'OXYVA).

One good example is the Masimo® iSpO2®, an accurate tool for everyday measurements of the most relevant vital sign to D'OXYVA such as PI or perfusion index that indicates peripheral blood circulation. More information is available on their website.

Moor Instruments FDA-cleared Imaging Diagnostic Test with Portable Masimo iSpO2

Following is a simple validation of both Moor's highly accurate imaging diagnostics and Masimo's handheld consumer diagnostic device. We asked a 60-year old volunteer to place her right hand under Moor's imaging device and Masimo's finger clip on her middle finger on her left hand at the same time. We asked her to avoid eating or drinking three hours prior to this test and to sit and rest for 10 minutes before start.

A separate person had operated the Moor and the Masimo diagnostics. Then both had measured baseline vitals and established her parameters before delivery of a single 5-minute D'OXYVA application on her left thumb. Both Moor and Masimo diagnostics were measuring during and after 60 minutes of the single D'OXYVA application to measure any changes.

Diagnostic Equipment

The moorFLPI-2 blood flow imager uses the laser speckle contrast technique to deliver real-time, high-resolution blood flow images, providing outstanding performance in a wide range of pre-clinical and clinical research applications. See more at: Moor Instruments

The iSpO2 comes in six versions—small and large options for connectors for iOS devices and micro USB for Android devices. The iSpO2 Masimo Personal Health app coupled with your iSpO2 allows you to track and trend your blood saturation (SpO2), pulse (heart) rate (PR), and perfusion index (PI).

Both Moor and Masimo were reading the same results in tandem. Both have recorded significant improvements of blood flow volume. The maximum blood flow volume improvement was nearly four times baseline. For example, Masimo's perfusion index (PI) baseline was 1.4 and the peak reading was 5.7. Masimo measures blood oxygen saturation as well (SpO2) and that increased from 96% to 100% (maximum).

Confidentiality Notice

Circularity is only allowed to post summary results publicly mainly to comply with various government regulations. We have been receiving and recording groundbreaking benefits for severe medical conditions. We are allowed to share these results privately and confidentially due to regulatory compliance requirements because our products are the subject of various human clinical trials seeking clearance by the U.S. Food and Drug Administration (FDA) and other health authorities around the world. Please email us at and share your experience so we can inform people about the great benefits of using D'OXYVA regularly (individual results may vary).
