The video works on destroying the virus and helps your immune system develop antibodies for it.
So the audio does not aggravate or increase the viral load. If it did, then our friend @Gnosticmedic27 would have the same issue your friend is having.
If the video didn’t work for your friend, then perhaps the field could use more research to ensure that it eliminates in all bodies. If it doesn’t work for others as well, then we shall remove it and work on researching it further.
Also, on how to use it, @Gnosticmedic27 gave the directions well. Even if they weren’t followed though, should have garnered results.
