Well today I emptied a 25mg capsule of Best Naturals Micronized Dhea under my tongue and it dissolved in 5 minutes, lol. 70% cheaper than the Douglas Labs micronized sublingual. Looking at the ingredients, the Douglas Labs probably dissolves quickly because it lacks the coating that comes on the Swanson and Life Extension sublinguals mentioned in my first post. Not sure why you want a coating on a sublingual anyway - the amazon reviews of Swanson and Life Extension sublinguals contain many complaints about not dissolving.
Am just wanting to minimize e2 conversion here if possible. Poking around online it seems that transdermal and sublingual have the least e2 effects in anecdotal reports and theory, though I could find no studies that verify it.
