Any word on how well it works, or why anyone would want that instead of the traditional dosage?

The ads are all over male-dominated tv shows... hunting, sports, history, warfare, etc. They are making a big push to plant the image of Androgel 1.62 into the minds of older men seeking or using Androgel. Probably, this is to drive them to ask their doctor about this higher concentration pump. I just don't understand what the advantage is. I mean, "Less Gel"? Is that a real concern?
