heeeeellppp please

Hello

New to this site and hoping I can get some help.

I live in the UK and things over here seem to be quite a bit different from the States. I have bought a Synergy WPS 400 ozone generator and having REAL problems with finding the UK equivalent of a CGA 540 Regulator. I cant import as the threads are different. In the UK our cylinder outlet is BS3 5/8, the problem im having is from what I have researched I can get welding oxygen with a purity of 99.7% but when it comes to the low flick style regulators where I need the different increment settings below 1LPM is when I begin to struggle as these don't seem to exist over here for some reason. and if they do they have a Pin index fitting which only medical grade oxygen cylinders have and cant get one of those with out a prescription. The UK seems to have BLOCKED any angle for ozone therapy seekers but I can go into any welding shop and walk out with in effect a small atomic bomb in the form of highly flammable oxygen cylinders for only £29,99.

AM I THE ONLY BRITISH PERSON TRYING TO DO OZONE THERAPY AT HOME???? I have spent over 20 hours in the last week along trying to figure this out. its almost like there's someone or something trying to stop me pursuing this but me being stubborn I will not give up unless it kills me which is stupid I know but I have spent to much money so far and to much time and I have to much determination its leading me to think of stupid ways to cut corners which no doubt will lead to injury or worse but I am becoming obsessed in figuring this out. unhealthy it is but I need to be able to use my dam ozone machine for what I purchased it for insufflation and ozonating water and olive oil.

IS THERE ANYONE IN THE UK THAT CAN HELP!!!!!!
