Would my client benefit from using CircO2 for supporting erectile function?

This will still be of benefit for now in helping you with acute administration prior to your desired activity. You have supplements you are taking to build within the capability to maintain high levels of nitric oxide production. That is a work in progress, because there are healing issues needing attention for your body to respond fully to what those supplements are designed to do. People think of supplements as adding back in what is missing, as though this could be like filling a cup with water. In actuality, there are multiple steps involved in the utilization by the body of such supplements, and sometimes the very biochemistry needed to fully utilize the supplement and have it engendered and express a desired physiologic change in capability, resilience, and productivity is being stunted by neglect or karmic interposition of negativity in some way to alter normal biochemical responses and pathways. So using this supplement is fine when it is simply a nutritional deficit alone. Although with underlying deeper causes for a deficit, the supplement will not be a magic key to switch back on something missing. But in concert with divine healing, this will support the divine healing efforts and in some cases will hasten return of a function because there will be a substitute for a deficient intake of key materials as well as the advantageous addition of a chemical signal supplied by the supplement for a part of a pathway, for example, needing to be reestablished and reinvigorated. And that will be all to the good because it will often be a kind of summoning, as a physical signal that will assist the divine in reawakening needed gene expression and keep a pathway on the rebound, so it is eventually fully functional and no longer needing a supplemental support.
