Hi Ivana
i am trying to find out the same thing. in fact, after contacting .eu and .nl (BGLI) i have discovered that there are tensions between them and claims that the others' gcmaf may be inactive/duds. both claim studies of activity and backed by dr's. i would really appreciate hearing from anyone with positive experience, and obvious effectiveness from their gcmaf and where they ended up ordering from. PM me if thats the way its done.. thanks
