I got to hang out with the man himself ( Eric ) last weekend at the Emerald Cup and asked him all sorts of questions. One was if holding Sustain Alpha under the tongue would help increase the absorption. In many words less than what he said, yes it will. So when I use my Liquavade Sustain Alpha, ill definatly be holding mine for one minute under my tongue. Btw, this is just my idea and im not suggesting anybody do it or condone it either.
