Gee Mark is that really all you want to know? Actually most commercial outfits I know of are using it to at least some extent, including myself. My personal opinion is that we only really know two things about it for sure one is that it is a stimulant and is highly attractive to bees, the other is that it is pretty danged expensive. For those reasons we have just been using it late winter and early spring together with pollen supplements to try to get queens going a bit earlier for pollination purposes. The one downside to the stuff is that it can encourage robbing and should be fed with care when that is a concern. As far as all the other claims I think that they are largely unproven. I take with a grain of salt statements like: "I fed this to all my bees and now they are really good". I wish more people would just use it on part of their hives and try to do more of a controlled experiment.
