There may be a bit of truth here. There are dozens of doctors and pet doctors on youtube telling about the dangers of Sulfa based drugs. I should have listened.
Of course, the advanced “stick in the nose” test with nanoparticles and cleaned with Ethylene Oxide (a known carcinogen) is a no-brainer. Do no harm...

always best to research products and not listen to ‘youtube doctors’ because many times they will not tell about the side effects or dangers associated with certain diseases and certain meds- they either don’t know, or neglect to mention them- I’ve run into numerous claims made by youtube doctors that have been refuted by actual medical journals and trials- plus im always wary of products because of soem conditions i have that could be worsened by side effects, ie lots of drugs pass through kidneys and strain them- having stage 4 nearly kidney disease i have to be very carful about products and their claims by internet docs-
