Like he said.... it probably wasn't MDMA long story short. But with actual MDMA, I prefer to pop .3, and snort .1... then go from there. That probably translates to popping .15... and snorting .05 for the average tolerance.
The buzz from eating it is actually a bit better than snorting IMO. But to me, the combo of eating a bit and snorting a bit is better than one or the other.
