Just consider Galeleo's trials and tribulations while trying to prove the earth revolved around the sun and Columbus' problems proving the world was round. As most of you already know, the body and particularly, the brain, run on an electro-chemical basis. It means that every thought, word and action has an electro-magnetic frequency. Since we are testing frequencies, the foods and supplements we usually test are actually being tested as a frequency. Thus there is nothing magical about it.
Surrogate testing proves it's hocus-pocus at best or fake at the worst.
In fact, if someone is electrocuted, the second person will get a higher charge than the first. Therefore, if a thought or substance weakens one person's frequency or even goes so far as to short-circuit it, then the others in that electrical circuit will respond accordingly. Thus the mystery of surrogate testing is laid to rest. You can't depend on the results-they change too frequently. If the response seems wrong, like testing strong for sugar or saccharine, then a couple of simple checks can provide a solution and then accuracy can be restored.
