I've just aquired some 5-iai, snorted a bit which didn't burn at all actually made my nose slightly numb, now just parachuted some because it wasn't doing anything, think I'm expecting instant fuckedness like meph but doesn't seem to be the case, hope it kicks in soon, feel a bit spacy and warm so far.
The stuff itself has virtually no odour whatsoever, there are huge lumps in it as well. tastes bitter as fuck, kind of like salt(hope it isn't that).
Just read on wiki that it is being sold as nrg-2 in some places, i hope to fuck this isn't the case!
