I have used Phlojel Ultra and made my own.  My homemade PLO was based on some recipe I found on Google scholar; it might require a subscription, if so just go to your local university library.  They were basically identical; the Phlojel texture was a bit nicer but functionally equivalent.

The aqueous layer is doom.  You need to pull down from the apolar solvent, or just incorporate the apolar solvent into the topical.  The all natural limonene Tek floating around is actually an ok starting point.  You can get a decent product with just a vacuum drying.  A gentle wash in a coffee filter and sublimation will take you the rest of the way - you'll get better crystal formation if there is a small amount of water to incorporate into the structure and the azole and amine groups are of opposite charge.  If you don't have a speed vac >) you could try placing dry ice and isopropyl alcohol in a styrofoam cooler, then placing your beaker with the apolar solvent and DMT in the ice bath VEEEERY SLOWLY while scraping around its inner surface with a glass rod very slowly until a precipitate forms on the tip.  This should be enough to nucleate a nice nugget of DMT while your solution is cooling, as long as you lower the temperature slowly.  This will work beautifully with some solvents, but poorly with others, though I would need to spend a bit of time with the Merck Index to tell you which it will be for your solvent of choice.
