^oy...so much wrong with that post.
DMT and DOB are two completely different chemicals. Two opposite sides of the psychedelic spectrum. DOB being a phenethylamine (2,5,4 dimethoxy amphetamine to be exact), and DMT being a tryptamine. DOB I find to be pretty bleh, where as DMT is really nice (which says a lot seeing as im more of a phenethylamine person rather than a tryptamine person)
Ketamine is nothing like a barb or a benzo though, its a dissociative. I suppose in smaller amounts it can feel like a benzo, or rather a few shots, but its a dissociative by nature and feels exactly like that. It comes as a liquid yes, and the process of dehydrating it is rather simple. There are many ways to do it, and I usually go with the steaming method as its the quickest way to dehydrate it without losing so much product. The best way to do it is by air drying it, but that takes a day or two. I usually dont get vials any more as id rather get large amounts of HCl than a few vials.
The synergy between DMT and ketamine is fantastic. I only did about 20mg of DMT and ~60mg ketamine to get a feel for the combo and I can tell that it would be great in higher doses. Getting the wobbly limb feelings while beginning to see very colorful outlines of objects was nice.
I suggest you read up on all of these chems both on Erowid, here on BL, and in TiHKAL and PiHKAL if you want to learn more about them. You definitely should learn more about them, my friend.
Now to go smoke another bowl and watch Dr. Steve Brule.
