Hi! thanks for your idea on skin thickness and
Androgel absorption. It seems to me that if what you say is true, then the drug manufacturer would want their product applied to both thick and thin skin areas so that the hormone would continually be supplied, a sort of timed release mechanism. This is not the case according to the directions supplied with Androgel, though. So, I'm afraid I still don't understand what their concern is and the rationale for it.
