I just sent away for my free sample. I've been searching the web for the active ingredients of "energel" but with no luck. Is this simply a mixture of "Icy Hot" (i.e. menthol, camphor, etc.) with caffeine or something totally new? The transdermal delivery system seems to be the DEGH claim to fame. No doubt this has many potential markets and could be a big money maker across a lot of industries. I figure I'll try this stuff out on the cat for 10 days to see what happens before testing it on myself.
