A company out of Hawaii called Pacific Exotic Spora (PES) advertises this strain as a cubensis/azurescens hybrid.
They even went so far as to claim it came from the mushroom master Paul Stamets himself.
Stamets have not published any information about being able to hybridize a Psilocybe azurescens with a Psilocybe cubensis.
They are completely different species and this task would certainly be extremely difficult.
But until something is published, do not buy into it. This is nothing more then a very potent cubensis.
