The German company you refer to is a breakaway from David Wagner. They stole the concept and terminology, but were unable to copy the technology. and you are correct, tachyon is pre-frequency/vibration. It is source of vibration, containing the potential for all vibrations, whichever one required for balance.

The tachyonization process is a quantum physics breakthrough, restructuring materials at the submolecular level to become PERMANENT antennae. it's a 2-week process in a lab.

Everyone I have ever used tachyon with, has FELT it!!!! even those who are not sensitive. all feel it differently....some feel warmth, some coolness, tingles, movement, pain (as in detox), bliss, relaxation, altered state, etc. Some hardly feel anything but feel a change and interestingly come back for more.....knowing that "something felt different."

At this point, there is no instrumentation to test tachyon....we can only observe and record the changes. The proof is in the experience.

Blessings and peace....
