Assuming that it's an actual, decent dose of MDMA, you would be able to get threshold effects at best if you were to eat it. Insuffulation would give a speedy, amped feeling, one that I'm not exactly a fan of. And tbh, snorting pills hurts like shit, and the drips SUCK. The most "intense" feeling would come from plugging it (AKA, sticking it up your bum). The proper way to do that is to crush the pill and mix it into a solution using ~5mL (iirc) of water and then using an oral syringe (the same type you would use to administer a liquid medication to a baby) to shoot the solution into your rectum. The most effective way to do this is to lay on your stomach, apply, and then lay there for a couple of minutes to allow the solution to absorb.
