I have. On one of my friends. I forget which one he got, but I think it was Pfizer. I used a tiny neodymium magnet, and I THINK it’s legit. I say that because it was muggy and humidity is bad down here, so maybe it’s a skin moisture thing? Either way, we tested it for several minutes. He could quickly move his arm in any direction without the magnet falling, to the point where it looked more like the skin was stretching for his movements, and it lost magnetism maybe? Not sure. But as I rolled the magnet across his skin, the magnet APPEARED to have a positive/negative feel to it as it got to the spot where he said he was injected. I brought out a stronger magnet to test him, and I don’t know if he was paranoid after seeing this magnet stick to him time and time again, but he said he could feel his skin pulling with the larger magnet and that it hurt him, so we ended that experiment. No BS. I’m still kind of on the fence about it, because I tested like 5 other people, and nothing happened. Why did it just work with him?
