Aside from the nonsense procedures, what's most glaringly obvious with these charlatans is the absence of methodology.
These people think you stick something in then walk way for for a year or two, yet selection criteria, donor/recipient segregation, de-spawning and post-op rehab never enter the picture. It sounds plausible between the inept, but to industry experts, no. These claims debunk themselves.
Using a dremel tool, silica gel and a chapstick is about as trying to pull wool over one's eyes as it gets. It's delusional and in this case, gaslighting and shaming that blew up in their face.
