It is beginning to appear on store shelves everywhere. My sister learned about it at a Weight Watcher's meeting from someone who would buy it out of town. After asking local stores to stock it, it started showing up in our hometown. It's lower in fat and calories, easy to mix up, and tastes good. Much better than Better'n Peanut Butter substitute made from who knows what and tastes terrible. We made a low calore peanut butter pie from skinny.com using it. It was delicious. Good on toast!
I typed in PB2 but when I posted the secret it shows up as Pb2 in the title. I don't know why.
