I use Ormus. Have used it for years. I use Energold, and suggest people find the one that works for them. Watch out for crappy fake stuff. The real deal is NOT cheap.

Psychic enhancer? Yes. It effects different people differently. My experiences have been good -- I can get into deep meditation faster, can read energies better, heightened sense of awareness. Some people have bad experiences -- such as seeing/sensing things they are not ready to handle, and do not know how to push away.

ETA: I was guided through my initial use by a master -- some of you might refer to the person as illuminati. He's really just a super intelligent, super intuned person.
