Slurry
By the fact that people are reading this, I assume most have a computer with a printer... Ink refill kits generally come with a 10ml syringe for the inks.
Instead, grind a pill up, pull out the plunger and pour the powdered pill into the barrel. Draw up a couple of millilitres of warm water, pull back a bit further, then shake. You should now have a slurry of MDMA pill which can be easily introduced to the colon by putting the tip into your rectum and pushing the plunger.
It comes on really quickly as by that point some of the drug is in solution (it needs to dissolve in order to pass through the intestinal wall), and doesn't involve getting a stinkfinger (it also feels a bit more comfortable).
I haven't used this method with MDMA, as I stopped using quite a few years ago, but I have used this method with countless other tablets of pharmaceutical drugs and plant extracts, most with an astonishing degree of success (most suprising effect was with methylphenidate - it's 4-5x the potency of the oral route for Ritalin).
Just remember not to use the syringe for anything else!
