This would not work particularly well because the active needs to be dissolved in order to increase the thermodynamic activity that drives diffusion. What you could do is dissolve it in ethanol or propylene glycol. You could also use cyclodextrins (but if you use them, go the intranasal route -- this is as effective as topicals if you do it religiously (every 2 hours), but obviously that is a bit of a pain. With sublingual deliery, the surface area is very limited, so unless you are a woman, or just using it for pre-workout, you really would have to use them almost constantly.
As a poster mentioned in the other thread, topical is the way to go. We make one, but it would obviously be rather biased if I recommended it, so I would recommend AndroSpray -- it is an excellent product.
