I get virtually no improvement with low levels, like under the 12 ml line, I do REALLY good over 50 ml, but is that too much? No one at the 800# on the pen knew what I was talking about. They don't make it, they are just the salesmen, and, apparently, I do not have security clearance to talk with the producers in Tennessee. So after waiting on hold with the salesman for 20 minutes, I was informed that it is a 70% and 30% mix, at which time I explained that yes I, too, can read the box. Doesn't anybody know how much of that white sediment should be there?
