Ive done it, it's pretty popular here in New Zealand- a hell of a lot of people exclusively IV MDMA powder, its almost got to the point that needle users buy powder while everyone else buys caps/pills. People have also started banging mephedrone and methylone too. Personally I find it all a bit concerning, it's introducing a lot of people well outside of the 'traditional' IV drug user circles.
The main thing that I'd say is that it becomes much closer to smoking/shooting meth than to simply swallowing some MD. It's fairly short lived, 4-6 hours, but it's got one mean rush...I mean it is much more loved up than straight methamp, but the rush is pretty incapacitating. You do feel great, but your heart is pounding out of your chest, you're sweating like a fucking pig and need a good sit down.
People tend to shoot around 60-120mg, it depends a lot on how experienced you are with stimulants (not so much 'empathegens', I mean straightforward hert pumping stimulants), what sort of tolerance you have, the quality of the powder & simply how big you are. An average sized man with a good amount of experience with MD and a bit of experience with meth can comfortably start with ~80g.
