Hi, I started PM yesterday 3/10/16. I bought Barlowe's PM from Amazon, it was a little cheaper than the barlowes.com. I read somewhere on this site last night that if your not sure if its real PM from Thailand, break open a capsule and taste it. So I did and its supposed to have no taste or a slight soy taste, and mine does have that soy taste. It also said if its bitter it isn't real, mines not bitter at all. A few days before I bought the PM, I bought a bottle BO, but after reading on this and a few other sites I decided to wait on the BO. I might consider using it at a later point, but not unless PM doesn't work much at all. Acacia Lynn
