Not a drug, but a device. First, go to YouTube and look up two series of videos posted by Mike702Dax, The Bob Beck Protocol, and The Bob Beck Protocol, How to Use It.
Then purchase the device from Sota Instruments in Canada. Feel free to email me before you buy - I may be able to help.
There are lots of other videos about this, but these are the best. There are other places to buy the device, but Sota is a great company with a reliable product, which is what you want if someone's life may rely on it.
