not tried it - but the guy has a good track record in mainstream research and held in good standing with his peers - his published peer reviewed papers are quite compelling and i think he has government grants to set up test labs and treatment clinics in USA, UK and a couple of countries in Europe
he basically demonstrates a common mechanism at work in chronic lyme, long covid and CFS - that explains why the symptoms are so similar - mainly errant white blood cells expressing antigens from pathogens for much longer than they should - driving vascular inflammation
he is mostly focussed on long covid- but explains that the people who come into his clinics with persistent fatigue dont typically know what they have - and via this testing be is able to tell what the root cause is -
he is finding around 20% have chronic lyme - another 10% have CFS and the remainder are long COVID
there was a project lyme video interviewing him also - which is a bit more focussed on lyme
