Any Pb2 eaters out there?

I just order from the pb2 and I really like it! Not quite as good as normal stuff, but close!! And there are no additives or preservatives and only 45 calls/ 2Tbs:) I can finally eat peanut butter again! Anyway, my question is when they say two tablespoons, is that of the powder or once you add the water? Not sure how much it matters but I wanted to be accurate.

Also have any tips of how to best use it? Thanks!
