If you put it in the freezer, does it turn from gooey to crystalline - and when taken out does it turn to goo again? I'm just curious, it would not even be a conclusive test for anything, whether regarding identity or purity.
It is a bit suspicious that it sounds like the description for DMT, but that would be pretty silly if he sent you that for free saying its dimethyl-B.F.E (I refuse to use the other term for now, lol)...
When it boils down to true research chemical studies there are a few things to think of, one is indeed to be extremely careful as was suggested. And really think about that for a minute too.
Check the psychedelic index, at the bottom there should be a link to a document Illuminati Boy wrote on how to approach bio assays like this.
Basically this is new territory and the best that could happen is you have a novel and wonderful experience, but you could also have very little effect - a horrible trip of trainwreck intensity or health concerns if you are unlucky. Of course men like Shulgin go through trial and error, but do so meticulously. And also, they have an understanding of biochemistry that might indicate metabolism problems. By that I mean the compound itself might not be immediately suspect, but it helps to know about how it will be broken down by the body - get as much info on it as you can.
No one here should tell you what you should or should not do, decide that for yourself. I'd like some tasty new info on a chem, but I also value what health you have now, even if I don't know you.
Maybe this could be laid out for the ADD boys, to see what potential problems they might anticipate.
