believe it or not, that video i posted that was that markus guy interviewing sloane had no errors in it regarding ozone. once you get a good kit you can breath ozone bubbled through olive oil, drink ozonated water, apply ozonated olive oil on the affected area, tape down a bag on that area and ozonate the skin, and do insulfations anywhere there is moist tissue (except for the lungs).
please, put your feelings aside and watch that together several times.
the guy who did my direct injection is black market. he is no kind of doctor yet he cures cancer and gangrene and my systemic bacteria infection for sure.
even cheaper machines are available and may be just fine. cold corona only. and only use an oxygen tank. no concentrators. just pure gas. get a welding bottle. then get this pediatric oxygen regulator to control the flow properly.
