Damn, thanks guys.
Follow up question: is it unheard of for someone to have an abnormally high natural tolerance to MDMA? For instance, after doing it multiple times at dosages between 100-250mg, respectively...with only effects being light-headedness, mild to moderate euphoria, and jaw clenching? There are definite change in cognitive state, but no light trails, feeling of "intimacy", or "life-changing" or "mind-blowing" euphoria (<---probably stronger words than needed, to some extent, but you get the point).
There is a possibility that every single dose from different sources could have been cut/diluted, but they were trusted and tasted exceptionally bitter.
inb4 testing kit (no doubt that MDxx was present...just questioning effects/dosage tolerance)
Hell...could just be expecting too much out of it, but the experience reports of others cause doubt.
