Which tachyon product to buy?

Hi,

I am new to energy healing. I have been doing Quantum Touch, and have successfully relieved my collegue's headache and my daughter's neck pain. I have been reading up on tachyon and think that it will be a really useful tool to combine with Quantum Touch. However, I have seen different "tachyon" or "tachyonized" products on the web, eby, etc. Knowing nothing about the actually tachyonization process, how can I know which one is the most effective, permanent tachyon product? How can I tell if someone is selling real tachyonized product but not just plain old glass beads? Please, any advice will be appreciated. Thank you so much!
