With the help of muscle tests, you can see if your nervous system works and you can even challenge yourself to see how you react to different substances and situations. To ensure the quality of the tests, you should put away your mobile phone, glasses, keys, money, necklace and what you want to test, about 2m away so that your body is "clean" and does not have to compensate for anything. Then stand up or lie down on a bench or a large table.
The simplest and best test we have found so far, to be able to ensure that you use good products, buy the right mobile phone, get a good massage oil and eat food that your body can handle, is a muscle test, where you yourself, together with someone else, can see how you react to external stimuli.
