In contrast to most of the phenethylamines, tryptamine freebases are solids. Which means that if you want to eat them, it really doesn't matter which form there in, because both solids are equally difficult to measure if you don't have a good weighing scale. If you want to smoke things, you definately want freebase. Snorting: dunno.
(my experience with freebase->HCl, & HCl->freebase: lossy. If you have to buy dpt, buy the freebase and store it in the fridge.)
